inner classses

[b bajwa]

How i can invoke inner class method. the code are the following
Code:
public class OuterOne
{
static private int x;
static public class InnerOne
{
private int y;
public void innerMethod()
{
int z=6;
System.out.println("enclosing z is "+z);
System.out.println("enclosing x is "+x);
System.out.println("y is "+y);

}
}
public void OuterMethod()
{
System.out.println("x is "+x);
}
public void makeInner()
{
InnerOne anInner= new InnerOne();
anInner.innerMethod();
}
public static void main(String args[])
{
OuterOne o=new OuterOne();
InnerOne i= new InnerOne();
//how i can invoke InnerMethod of the static
// inner class
i.InnerMethod(); // not working
o.InnerMethod(); //Not working
}
}

Hi b,
You are having case sensitivity problems. The first choice would work if you had the case of I correct:
Method created: innerMethod
Method called: InnerMethod
See a problem here. Change your first "not working" call to:
i.innerMethod();
and all is well.
Regards,
Manfred.

you are instantiating the outer class by saying new OuterOne() & you are trying to call the inner class method from the outerclass object & thats why you are are not able to get it working..Here is what you have to do:
OuterOne.InnerOne inn = new OuterOne.newInnerOne(); //Inner class
inn.innerMethod(); // call inner class method
Remember that you always have to create an object of the outer class before you create an object of the inner class.
Let me know if you need more info...
Hope my explanation helped

Inner class is static, so you dont need an instance of the outer class, all you need is a instance of inner class i.e
new InnerOne().innerMethod();
OR
InnerOne i= new InnerOne();
i.innerMethod();
OR
OuterOne.InnerOne io = new OuterOne.InnerOne();
io.innerMethod();
