Hi,
<h5><code>
public class test {
static int x;
static int y;
static final int z=0xaa;
int s=0;

public static void main(String args[]){
System.out.println(x);
System.out.println(y);
System.out.println(z);
new test().hello();
//hello();
}
void hello(){
System.out.println(s);
}
}
</code></h5>
When i tried to run this program it is working good,but when i tried to run the program by uncommenting the line //hello() i'm getting the error
test.java:14: non-static method hello() cannot be referenced from a static context
hello();
^
1 error
Though i can roughly understand the error,I' couldn't able to compeltely understand the error context with JLS reference if available..

Hi ,
The method hello() is a instance method. So you can't reference hello() from static method (main).
Refer JLS 8.4.3.2 static methods

hi,
Staic variables can be accessed by both static and nonstaic methods but Non-Staic variables can be accessed by only nonstaic methods while static methods can call only other static methods and nonstatic method can call only other nonstatic mathods.
Am i right?
