Post the error message here..


String is a class . it should be capital.

public static void main(String[] args)

when i'd compile by javac HelloWorldApp.java the error becomes :

error: cannot read: HelloWorldApp.java 1Error

well, that just means the compiler either can't find the source file or you've got the file permissions set for it to be not readable for the compiler.

If you are compiling from command prompt , make sure that you are in the same directory where your source file is present.

you right sir but,
right now,I've copy and paste that file into bin folder of jdk.
then i've copy the path of bin folder and wrote in comand prompt :

cd path of bin folder

then hit 'enter' its done and after that when i try to compile again same Error becomes again.
one thing when i ignore that error and do the next step wrote java HelloWorldApp.java and hit the 'enter' as a result my coded notepad file names HElloWApp.java opens.
i think i should try to listen the basic lecture again.
