Static in Java

[Jay Shukla]

Hey i have read Somewhere...

"The rule is, a static method of a classs can't access a nonstatic(instance) method or varaible of its own"

Does it mean that that staic mathod can access nonstatic(instance) method or variable of other...

One more Doubt:

i can declare nonstatic variable in static method an I right?

[Chandra Bhatt]

hi Jay,

Statement is correct. Static method can't access non static member
variables, because inside static method there is no "this" reference

Did you try that?

method or variable of other...

Other means, is that practically tried by you.

Hi Chandra , Yes, i have tried. And it succcessfully worked.

 
package tst;
 
/**
 *
 * @author Jay Shukla
 */
class A{
    int i = 10;
}
 
public class B {
 
    /**
     * @param args the command line arguments
     */
    public static void main(String[] args) {
        // TODO code application logic here
        A a = new A();
        System.out.println("Value of i in other class : " + a.i);
                
        
    }
 
}
 

Above code gave me an o/p :
Value of i in other class : 10
 
Thanks a lot!!!

And you can't create static or "non-static" (probably better called "instance") variables in a static method; you can only create local variables.
