Thread: Learning Java ~ What are the best choices of tools ?

Wait for one day I am installing windows to solve this issue. Can't understand as path is showing bin in the path.

hey luke, sorry i forgot to update here, nandini's method is working fine. now both javac and java command are working from cmd.

thanks for your help.

meanwhile what is wrong in this code ?

public class MyFirstApp
{
public static void main ()
{
System.out.println("I rule ");
System.out.println("the world.");
}
}

Saved as MyFirstApp.java.

NO problems in compiling , but in execution i get this error.

F:\Documents and Settings\Administrator\Desktop>java MyFirstApp
Exception in thread "main" java.lang.NoSuchMethodError: main

F:\Documents and Settings\Administrator\Desktop>java MyFirstApp.class
Exception in thread "main" java.lang.NoClassDefFoundError: MyFirstApp/class
Caused by: java.lang.ClassNotFoundException: MyFirstApp.class

Could not find the main class: MyFirstApp.class. Program will exit.

Write main statement as

public static void main (String[] args)

So program is:-

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




PS: Then I am not going to install windows.

thanks again, finally i got one program working
