Answer / sonu

No never we cannot override the static methods becouse overriding is done only run time and static methods get memory at compile time and static things not the part of object.

static class Class1 {
    public static int Method1(){
          return 0;
    }
}
static class Class2 extends Class1 {
    public static int Method1(){
          return 1;
    }




}
public static class Main {
    public static void main(String[] args){
            
          Class1.Method1();
          Class2.Method1();
    }
}

Remember that static methods can't be overridden! This doesn't mean they
can't be redefined in a subclass, but redefining and overriding aren't the same thing.
Let's take a look at an example of a redefined (remember, not overridden), static
method:


class Animal
{
static void doStuff()
{
System.out.print("a ");
}
}
class Dog extends Animal
{
static void doStuff()
{
// it's a redefinition,
// not an override
System.out.print("d ");
}

public static void main(String [] args)
{
Animal [] a = {new Animal(), new Dog(), new Animal()};
for(int x = 0; x < a.length; x++)
a[x].doStuff();
// invoke the static method
}
}

/*
Running this code produces the output:
a a a
*/

Here redefining means that you declare a static method with the same signature as the supper class'. So the same method in super class is redefined in the subclass. As you already know that the static methods can't be overridden so this is what you can do if you want the static method to behave differently in the subclass. But remember you can't have the polymorphism since no overridden happens.

Answer / durga

We can't override static methods,becoz static methods are loaded at class loading time,so it is class level.but we overload static methods.

Say you want to store the information about a number of pets in an array. Typical information that you could store for each pet (where relevant) would be • Breed of animal • Animal's name • Its birth date • Its sex • Whether it has been sterilised or not • When it is due for its next inoculation • When it last had its wings clipped For each type of pet (eg. dog, cat or bird) you would typically define a class to hold the relevant data. Note: You do not need to implement these classes. Just answer the following questions. 3.1.1 What would be the advantage of creating a superclass (eg. Pet) and declaring an array of Pet objects over simply using an array of Objects, storing each of the instances of the different pet classes (eg. Dog, Cat or Bird) in it? 3.1.2 Would you define Pet as a class or as an interface? Why? (2) (2)

If I will write String s=new String("XYZ"); String s1=new String("XYZ"); if(s.equals(s1)){ sop("True"); } else{ sop("False"); } This program will give me "True". But When I am creating my own class suppose class Employee{ public Employee(String name); } Employee e= new Employee("XYZ"); Employee e1 = neew Employee("XYZ"); if(e.equals(e1)){ sop("True"); } else{ sop("False"); } Then it will give the output as "False". Can I know what is happening internally?
