JAVAHOME=c:\>Program Files (x86)\java\jdk1.7.0_11\bin
PATH=%PATH%;%JAVAHOME%
cd <directory where="" your="" java="" source="" is="" stored="">
javac MyFirstApp.java
java MyFirstApp
</directory>

Alternatively get a copy of Netbeans or eclipse and run from within the IDE.

Solution 1

You should invoke the javac command from the folder MyFirstApp.java is. See the example at the documentation page[^].

[Update]
I fixed two errors in your code.

Your class should be declared public.
args type is String (instead of Strings).

The following code compiles and executes fine:

Java

import java.io.*;

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

You shouldn't invoke javac from MyFirstApp.java. Instead you should invoke javac from MyFirstApp.java folder: If MyFirstApp.java is in "C:\Documents\MyPrograms" then you should issue:
cd C:\Documents\MyPrograms
javac MyFirstApp.java

import java.io.*;
class hai
{
public static void main(Strings args[])
{
System.out.println("hai ");
}
}
showing error as
public static void main(String args[])
symbol:Strings
location:class hai
while running
