In this tutorial how to Perform Class Inheritance in Core Java\u00a0 is shown.<\/p>\n
Code:<\/p>\n
InheritanceDemo.java<\/p>\n
class A
\n{
\nprivate int a,b;<\/p>\n
A()
\n{
\na=b=1;
\n}<\/p>\n
A(int a,int b)
\n{
\nthis.a=a;
\nthis.b=b;
\n}<\/p>\n
void display()
\n{
\nSystem.out.println(“A: “+a);
\nSystem.out.println(“B: “+b);
\n}<\/p>\n
}<\/p>\n
class B extends A
\n{
\nprivate int c;<\/p>\n
B()
\n{
\nsuper();
\nc=1;
\n}<\/p>\n
B(int c,int a,int b)
\n{
\nsuper(a,b);
\nthis.c=c;
\n}<\/p>\n
void displayb()
\n{
\ndisplay();
\nSystem.out.println(“C: “+c);
\n}
\n}<\/p>\n
public class InheritanceDemo
\n{
\npublic static void main(String[] args)
\n{
\nB b2=new B();
\nb2.displayb();
\nB b1=new B(6,7,8);
\nb1.displayb();
\n}
\n}<\/p>\n
