Adobe Flash i Java dva su preuzimanja koja je većina nas instalirala na svoja Windows računala jer nam daju bogatije iskustvo interneta i pregledavanja. Već smo vidjeli kako upravljati postavkama Adobe Flasha . Danas ćemo naučiti o Java postavkama^{(Java Settings)} u Windows 10/8/7 .

Što je Java

Java je programski jezik^{(Java is a programming language)} i računalna platforma koja pokreće najsuvremenije programe uključujući uslužne programe, igre i poslovne aplikacije. Omogućuje vam igranje online igrica, razgovor s ljudima diljem svijeta, gledanje slika u 3D-u i još mnogo toga.

Java upravljačka ploča

Java softver ili Java Runtime Environment također se naziva Java Runtime , Runtime Environment , Runtime , JRE , Java Virtual Machine , itd. Njime se može upravljati s Java Control Panel- a . Za pristup Java Control Panel , otvorite Control Panel i kliknite na Java . Ovdje ćete moći dobiti informacije o broju verzije i pogledati^(View) datoteke.

Uklonite privremene Java datoteke

Prilikom pregledavanja interneta, kad god vaš preglednik koristi Javu^(Java) , Java datoteke se pohranjuju u posebne mape za brže izvršavanje kasnije.

Da biste vidjeli lokaciju mape i ostale pojedinosti, kliknite na gumb Postavke^(Settings) .

Prema zadanim postavkama, ove privremene java datoteke pohranjene su u

C:\Users\Username\AppData\LocalLow\Sun\Java\Deployment\cache

mapu u JAR formatu. Možete postaviti razinu kompresije za ove JAR datoteke, pa čak i količinu koju treba izdvojiti za pohranjivanje tih datoteka.

Da biste izbrisali ove privremene Java JAR datoteke, kliknite na Izbriši datoteke^{(Delete Files)} . Sada možete odabrati koje datoteke želite izbrisati i kliknite na OK.

Očistite Java predmemoriju pomoću naredbenog retka

Za brisanje Java predmemorije pomoću naredbenog retka, otvorite prozore naredbenog retka, upišite sljedeće i pritisnite Enter:

javaws -uninstall

Java ažuriranje

Skloni smo zanemariti ažuriranje naše Jave. ^{(We tend to ignore updating our Java.)} No vrlo je važno da uvijek pazimo da koristite najnoviju verziju Jave^(Java) budući da se ranjivosti u Javi^(Java) često iskorištavaju kako bi kompromitirali vaše računalo. Najnovija verzija Java sadrži važna poboljšanja za poboljšanje sigurnosti, performansi i stabilnosti Java aplikacija koje se pokreću na vašem računalu. Kad god^(Whenever) se otkriju sigurnosne rupe, one se zakrpe i stoga je neophodno osigurati da imate instaliranu najnoviju verziju java jer uključuje ispravke ranjivosti.

Postavke ažuriranja Jave^(Java) možete konfigurirati klikom na karticu Ažuriranje^(Update) .

Provjerite je li označena opcija Provjeri ažuriranja automatski^{(Check for Updates Automatically)} . Klikom na gumb Napredno^(Advanced) omogućit će vam postavljanje učestalosti provjera ažuriranja.

Usput, primijetio sam da je prošlo dosta vremena otkako sam ažurirao Javu^(Java) . Stoga sam kliknuo na Ažuriraj sada^{(Update Now)} da bih započeo proces ažuriranja. Time se pokreće proces juscheck.exe koji će provjeriti je li ažuriranje dostupno i o tome vas obavijestiti.

Klikom na Instaliraj^(Install) pokrenut će se proces ažuriranja. Kada se završi, kliknite na Zatvori^(Close) .

Ostale Java postavke

Kartica Java vam omogućuje pregled i upravljanje verzijama Java Runtimea^{(Java Runtime)} i postavkama za Java aplikacije i applete.

Kartica Sigurnost^(Security) omogućuje vam pregled vrste certifikata za identifikaciju.

Kartica Napredno^(Advanced) omogućuje konfiguriranje drugih postavki.

Deinstalirajte stare Java verzije

Održavanje starih i nepodržanih verzija Jave^(Java) na vašem sustavu predstavlja ozbiljan sigurnosni rizik.

Older versions of SunJava (up to JRE 6 update 7) indeed did remain when updates were installed and need to be removed as the older versions of SunJava are highly vulnerable to Winfixer/Vundo. It took from 2005 until the update late last year to JRE 6 update 10 for SunMicrosystems to Sun Microsystems to get the autoupdater of SunJava to uninstall previous (vulnerable) versions of the program. Updates from JRE 6 Update 10 forward are in a self-contained “jre6” folder that is overwritten if a new JRE is installed. Even when using the most up-to-date version of SunJava, if older, vulnerable, version(s) are still on your computer, it is vulnerable to infection. Unfortunately, simply using Add/Remove programs to uninstall the old versions is not completely affective.

Predlažemo da isprobate JavaRa . Nakon što sam danas ažurirao Javu^(Java) na najnoviju verziju, pokrenuo sam JavaRa i koristio je za uklanjanje starijih verzija Jave .^(Java)

Otkrio je dvije starije verzije na mom računalu, koje sam potom uklonio.

BILJEŠKA. ^(NOTE.)Moj MVP kolega i TWCF Mod Corrine dodaje: JavaRa nije ažurirana kako bi podržala uklanjanje JRE 7 i čini se da ima problema s JRE 6u32 . Premješteno je na SingularLabs.com . Osim toga, Paul McLain više ne podržava JavaRa , ali Freð ðe Vries još uvijek podržava.

Java Download

Javu^(Java) za Windows možete preuzeti i instalirati ručno s Java.com ovdje^(here) .

Nadam se da ste naučili nešto novo ovdje u ovom postu. Ako imate još nešto za dodati, učinite to u odjeljku za komentare.^{(Hope you have learned something new here in this post. If you have anything more to add, please do so in the comments section.)}

Manage Java Settings in Windows 11/10

Adobe Flash and Java are two downloads most of us have installed on our Windows computers, as they giνe us a rіcher internet and browsing experience. We have already seen how to manage Adobe Flash Settings. Today we will learn about Java Settings іn Windows 10/8/7.

What is Java

Java is a programming language and computing platform, which powers state-of-the-art programs including utilities, games, and business applications. It allows you to play online games, chat with people around the world, view images in 3D, and more.

Java Control Panel

Java software or the Java Runtime Environment is also referred to as the Java Runtime, Runtime Environment, Runtime, JRE, Java Virtual Machine, etc. It can be managed from the Java Control Panel. To access the Java Control Panel, open Control Panel and click on Java. Here you will be able to get information on the version number and also View the files.

Remove temporary Java files

When browsing the internet, whenever your browser uses Java, the Java files are stored in special folders for quicker execution later on.

To see the location of the folder and other details, click on the Settings button.

By default, these temporary java files are stored in the

C:\Users\Username\AppData\LocalLow\Sun\Java\Deployment\cache

folder in the JAR format. You can set the compression level for these JAR files and even set the amount to be set aside for storing these files.

To delete these temporary Java JAR files, click on Delete Files. Now you can select which files you wish to delete and click on OK.

Clear Java cache using command line

To clear Java cache using the command line, open a command prompt windows, type the following and press Enter:

javaws -uninstall

Java Update

We tend to ignore updating our Java. But it is very important that we always make sure that you are using the latest version of Java since vulnerabilities in Java are often exploited to compromise your computer. The latest Java version contains important enhancements to improve the security, performance, and stability of the Java applications that run on your machine. Whenever security holes are detected, they are patched, and it is therefore imperative that you ensure that you have the latest version of java installed as it includes vulnerability fixes.

You can configure the Java update settings by clicking on the Update tab.

Make sure that the Check for Updates Automatically is checked.  Clicking on the Advanced button will let you set the frequency of the update checks.

By the way, I noticed that it was a long time since I had updated Java. So I clicked on Update Now to start the update process. This starts the juscheck.exe process, which will check if an update is available and accordingly inform you.

Clicking on Install will start the update process. Once it is completed, click on Close.

Other Java settings

The Java tab lets you view and manage the Java Runtime versions and settings for Java applications and applets.

The Security tab lets you view the type of certificates to identify yourself.

The Advanced tab lets you configure other settings.

Uninstall Old Java versions

Keeping old and unsupported versions of Java on your system presents a serious security risk.

Older versions of SunJava (up to JRE 6 update 7) indeed did remain when updates were installed and need to be removed as the older versions of SunJava are highly vulnerable to Winfixer/Vundo. It took from 2005 until the update late last year to JRE 6 update 10 for SunMicrosystems to Sun Microsystems to get the autoupdater of SunJava to uninstall previous (vulnerable) versions of the program. Updates from JRE 6 Update 10 forward are in a self-contained “jre6” folder that is overwritten if a new JRE is installed. Even when using the most up-to-date version of SunJava, if older, vulnerable, version(s) are still on your computer, it is vulnerable to infection. Unfortunately, simply using Add/Remove programs to uninstall the old versions is not completely affective.

We suggest you try JavaRa. After updating Java to its latest version today, I ran JavaRa and used it to remove older Java versions.

It detected two older versions on my computer, which I then removed.

NOTE. My MVP colleague and TWCF Mod Corrine adds: JavaRa hasn’t been updated to support the removal of JRE 7 and seems to have trouble past JRE 6u32. It has moved to SingularLabs.com. In addition, Paul McLain no longer supports JavaRa, but Freð ðe Vries still does.

Java Download

You can download and install Java for Windows manually from Java.com here.
