Question

I have intalled JDK 6 Update 2 with NetBeans 5.5.1. netbean is shown on the screen and can be opened to use. I dont know how to open JDK6. I know it exists in the program files as the "Java" file. I got into "jdk1.6.0_02" in the "Java" file and I saw alot of files and documents. Please tell me how to just open JDK and use it. Sincerely

Answer 1

JDK is collections of Java libraries in JAR files. You cannot open JDK perse but you can see the content of jar file by executing: jar tf something.jar. You can extract the jar file which give you many class files. If you want to study the Java code itself, you need to download the source code.

Anyway, for standard development, you don't need to open JDK. Netbeans uses JDK automatically when it compiles your code.
