Hi Here is the Example for Method Overloading:

class A{
  public void fun1(int x){
    System.out.println("The value of class A is : " + x);
  }
  public void fun1(int x,int y){
    System.out.println("The value of class B is : " + x + "
and " + y);
  }
}
public class polyone{
  public static void main(String[] args){
    A obj=new A();
// Here compiler decides that fun1(int)
is to be called and "int" will be printed.
    obj.fun1(2);   
// Here compiler decides that fun1(int,int)
is to be called and "int and int" will be printed. 
      obj.fun1(2,3);       
  }
}


And Method Overriding:

class A{
  public void fun1(int x){
     System.out.println("int in Class A is : "+ x);
  }
}

class B extends A{
  public void fun1(int x){
     System.out.println("int in Class B is : "+ x);
  }
}

public class polytwo{
  public static void main(String[] args){
     A obj;
     
     obj= new A(); // line 1
     obj.fun1(2);  // line 2 (prints "int in Class A is :
2")
     
     obj=new B();  // line 3
     obj.fun1(5);  // line 4 (prints ""int in Class B is :
5")


I think these are very very basic program example for
Method Overloading and Overriding...
