What is the output of the below Java program with an Interface?interface Car { int basePrice = 1000;}public class InterfaceTest2 implements Car { void changePrice() { basePrice = 2000; System.out.print(basePrice); } public static void main(String[] args) { new InterfaceTest2().changePrice(); }}Options1000Compiler errorNone of these2000

What will be the output of the following Java program?interface calculate { void cal(int item);}class display implements calculate { int x; public void cal(int item) { x = item * item; }}class interfaces { public static void main(String args[]) { display arr = new display(); arr.x = 0; arr.cal(2); System.out.print(arr.x); }}Options04Compiler Error2

what is interface?Explain its significance in Java

Predict the outputclass Car implements Insurance{        public int calcPremium(int i)    {        return i = i * i;    }}interface Insurance{    int calcPremium(int i);}public class MainClass {    public static void main(String[] args)    {        Insurance b = new Car();        System.out.println(b.calcPremium(2));    }}Select one:a.The output will be 4b.Compile time error because you must create interface before implementing it.c.Compile time error because you cannot create an object of type interface Insuranced.Run time Error
