Hi, we can overried the static method as well as we can
overload them. The exam which you have given is wrongly
interpreted. Never try to access the static method with the
instance variable, it can create confusion.

In the Foo, Bar example if you do like this
Foo f = new Bar();
and call f.(some staic method). It will always call the
static method of Foo (but not of Bar). Check the java docs.
So just modify the code like this

class Foo {
public static void classMethod() {
System.out.println("classMethod() in Foo");
}

public void instanceMethod() {
System.out.println("instanceMethod() in Foo");
}
}

class Bar extends Foo {
public static void classMethod() {
System.out.println("classMethod() in Bar");
}

public void instanceMethod() {
System.out.println("instanceMethod() in Bar");
}
}

class Test {
public static void main(String[] args) {
class Foo {
public static void classMethod() {
System.out.println("classMethod() in Foo");
}

public void instanceMethod() {
System.out.println("instanceMethod() in Foo");
}
}

class Bar extends Foo {
public static void classMethod() {
System.out.println("classMethod() in Bar");
}

public void instanceMethod() {
System.out.println("instanceMethod() in Bar");
}
}

class Test {
public static void main(String[] args) {
Foo f = new Foo();
f.instanceMethod();
Foo.classMethod();

Foo b = new Bar();
b.instanceMethod();
Bar.classMethod();
}
}

If you run this, the output is
instanceMethod() in Foo
classMethod() in Foo
instanceMethod() in Bar
classMethod() in Bar
