class d {
int a[] = new int[5];
int i = 1;
void increase(int a[]) {
a[i] = 2;
}
public static void main(String args[]) {
d f = new d();
f.increase(a);
System.out.println(a[2]);
}
}
this code is giving error that a is not static. I don't understand why it is giving the error

when u r accessing a instance variable from the a static method ( main is a static method ) the instance variable must also b static. so u r method invocation would work only if u say
f.increase(f.a);
else u have to declare a local array of integers in main and then pass it to the method say
public static void main(String[] args)
{
int a[] = new int[5];
f.increase(a);
} -- this will not give you
the error that a is not static

hi Shabbir,
problem with your code is that u r trying to access instance variable a in main without a object of class d.
your main should be like this==>
public static void main(String args[]) {
d f = new d();
f.increase(f.a);
System.out.println(f.a[2]);
}
I hope this helps you.
