Is Java really necessary

Hi,

Can anyone tell me what is the purpose of having Java. I uninstalled mine at the suggestion of a friend. I can browse the Internet and do not notice any change. I would just like to be certain that it is not needed for normal user. On the other hand, what benefits are there in having it installed.

Any input will be appreciated.

Hi TonyT,

Thank you so much for your reply. I do have another question. If I wanted to create a web page would I, then, need Java? TIA.

 

It's not necessary to have Java, but as TonyT mentioned, some applications call for it. You could install the latest version, and set your browser or security software to prompt you if a java application is launched.

You can test a machine's Java version here.

Java Script?

Continuing along the same lines.... what is the purpose of java script? How does it relate to Java? Is "it" necessary for everyday usage? I've heard that java script can carry potential security problems and have wondered about the necessity of having it "turned on" in my browser. TIA

 

Hi, James.

Both Java and Javascript have had security vulnerabilities addressed in the past. You could try browsing with both of them turned off and see how they affect your browsing experience.

I leave Javascript enabled on my computer (for convenience) because at least some of my favorite sites make use of Javascript. I turn Java on only when I plan to use a site that requires Java (such as Secunia's Software Inspector). After using a site that requires Java, I immediately turn Java off and exit out of my browser.

• HTML Goodies (Joe Burns): Java vs. JavaScript
• developer.com (Joe Burns): Java vs. JavaScript: So... what is the difference between Java and JavaScript anyway?

If you want to study further, then you might want to view links provided by Googling differences between java and javascript.


EDIT: If you find Java does not work at Johanna's link to a Java version tester site or Secunia Software Inspector after enabling Java in your browser, you might need to configure your firewall to allow Java applets to be executed from those sites.

 

Thanks TonyT - Sorry I took so long to get back here, but I had a Trojan scare
that kept me pretty busy.
