Single Base_class | | Single Derived_ class //Single Inheritance in Java class examp1 { public int a=10,b=20,c; public void add() { c=a+b; } } class examp2 extends examp1 { public void display() { System.out.println("a="+a); System.out.println("b="+b); System.out.println("c="+c); } } class example { public static void main(String args[]) { examp2 obj=new examp2(); obj.add(); obj.display(); } }
