Java does not support Multiple Inheritance but you can show it by implementing multiple interface.

interface IntefaceA {
      void method1();
}
interface InterfaceB{
      void method2();
}
interface Interface extends IntefaceA,InterfaceB {
  void method3();
}
class InterfaceExample implements Interface {
  public void method1() {
    System.out.println("Method1.....");
  }
  public void method2() {
    System.out.println("Method2.....");
  }
  public void method3() {
    System.out.println("Method3.....");
  }
  public static void main(String arg[]) {
    InterfaceExample ex = new InterfaceExample();
    ex.method1();
    ex.method2();
    ex.method3();
  }
}
