i have installed fedora 8 -i386 version on my lap..
can neone tell me how to run hello.java program in fedora8

suppose i have made a program

class hello
{
public static void main(String args[])
{
System.out.println("hello world");
}
}


now wat shall i do to run it...

1. Compile it
javac hello.java

2. Run it
java hello.class

Running scripts from the command line is good because if they crash any errors they spit out will be displayed in the terminal for you to read over.

Edited cause' the question was answered above.

Add public specifier to else your class becomes private.

my program got compiled successfully but when i typed java hello.class
i got the following error..
java hello.class
Exception in thread "main" java.lang.NoClassDefFoundError: hello/class
