In this tutorial how to create a Interface and implement in Core Java\u00a0 is shown.<\/p>\n
Code:<\/p>\n
Interface.java<\/p>\n
interface Test
\n{
\nabstract public void disp();
\n}<\/p>\n
class A
\n{
\nint a=100;
\n}<\/p>\n
class Dummy extends A implements Test
\n{
\npublic void disp()
\n{
\nSystem.out.println(“Inside Interface”);
\n}
\n}<\/p>\n
class TestInterface
\n{
\npublic static void main(String args[])
\n{
\nDummy d=new Dummy();
\nd.disp();
\nSystem.out.println(“A: “+d.a);
\n}
