Simple Example for Inheritance

SuperClass.java:

package com.core.Inheritance;

public class SuperClass {
int num1;
int num2;
void SetValue(int no1, int no2){
num1 = no1;
num2 = no2;
}
}

SubClass.java:

package com.core.Inheritance;

public class SubClass extends SuperClass{

void multi(){

System.out.println("SubClass nulti val is : "+(num1 * num2)); //accessing member of superclass from subclass

}

}

Inheritance.java:

package com.core.Inheritance;

public class Inheritance {

public static void main(String[] args) {

SubClass subClass = new SubClass();

subClass.multi(); 

subClass.SetValue(3, 4);//calling superclass method throgh subclass object

subClass.multi();

}

}

OutPut:

SubClass nulti val is : 0

SubClass nulti val is : 12
