Create a Java class with 3 methods derived from an interface such as basic example below. Have your methods perform some sort of function. Try to have your methods use an argument (example int intNum). Have one method throw an exception. interface Infit public void method10: } interface Inf2 extends Inf1 { public void method20: > public class Demo implements Inf24 Even though this class is only implementing the * interface Inf2, it has to implement all the methods * of Inft as well because the interface inf2 extends inf1 */ public void method104 System.out.println('method1% > public void method 20 System.out.println("method2"> } public static void main(String args() Inf2 obj - new Demo(): obj.method20: }
