Answer 4

you can override static method (but only) with other static method

class Test{
public static void main(String[] args) {
var b = new ClassB();
b.doSomething();
} }
class ClassA {
static void doSomething() {
System.out.println("in Class A");
} }
class ClassB extends ClassA {
static void doSomething() {
System.out.println("in Class B");
} }

//output: in Class B

Answer 5

//another example. Static variable keeps the same value for all instances of class

class Stat {
static int num;
}
class Main {
public static void main(String[] args) {
Stat.num = 1;
Stat.num++; //num=2

var A = new Stat();
A.num++; //num=3

var B = new Stat();
B.num++; //num=4

System.out.println(B.num); //output: 4
}
}
