Anonymous Inner Class

[podonga poron]

class test1 {
public void method1() {}
}

class test2 {
test1 p = new test1() {
public void method1() {}
public void method2() {} //where method2 goes ??
};
}

class access {
void access(){
test1 t = new test1();
t.method1(); //perfect i can access to method1
//but HOW can i access to anonymous method2 ??
}
}

Can't be done (except by using reflection.) The only methods you can access normally are those accessible through the type of the reference variable.

ok, so the method2() is lost in the heap with no reference ?

what is reflection ?

thanks !

No, a method is not a separate object, so it's not that; it's just that there's no Java syntax to refer to that method.

"Reflection" is a kind of magic way to create objects and call methods based only on Strings containing their names; it's implemented in the java.lang.reflect package. It's not used much in normal programming, but it's used a lot by IDEs, Web containers, JavaBean containers, etc.
