Given the following, 1. interface Base { 2. boolean m1 (); 3. byte m2(short s); 4. } Which code fragments will compile? (Choose all that apply.)

interface Base2 implements Base { }

abstract class Class2 extends Base { public boolean ml() { return true; } }

abstract class Class2 implements Base { }

abstract class Class2. implements Base { public boolean m1() { return (true); } }

class Class2 implements Base { boolean m1( ) { return false; } byte m2(short s) { return 42; } }
