static in a method

[Krishna Tota]

Hi,

public class Test{
public int aMethod()
{
static int i=0;
i++;
return i;
}
pblic static void main(String a[])
{
Test t=new Test();
t.aMethod();
int j=t.aMethod();
System.out.println(j);
}
}
What is the rong with this code.
please explain in brief.
Thanks.

Java does not support static variables inside methods like C and C++ do. Instead, you should make the variable a class or instance variable:

public class Test
{
    // or non-static if you want to register it for instances only
    static int i = 0;
 
    public int aMethod()
    {
        i++;
        return i;
    }
 
    pblic static void main(String a[])
    {
        Test t = new Test();
        t.aMethod();
        int j = t.aMethod();
        System.out.println(j);
    }
}

You can not mark local variable as static

Method-local variables( those declared inside a method) can't have the modifiers public, private, protected, transient, syncronized, abstruct, strictfp, static. They can only have the modifier final.
