Question 1 1 pts What would be the correct line of code needed to declare a JLabel called StartLabel that displays the message "Starting program"? JLabel StartLabel = new JLabel("Starting program") StartLabel = new JLabel("Starting program") O JLabel l = new JLabel("Starting program") O JLabel StartLabel - JLabel() Question 2 1 pts The method defined on line ____ overloads the method defined on line ---- /* 1 */ interface Myinterface { /* 2 */ int number() /* 3*/ } /* 4 */ abstract class Abs { /* 5 */ static int foo = 12 /* 6*/ int number() { return 5} /* 7 */ abstract int acel) /* 8*/ } /* 9*/ final class Sub extends MainClass { /* 10 */ Sub(int bar) { foo = bar /* 11 */ int number() { return 10 } /* 12 */ int acel) { return 13} /* 13 */ int dubble(int i) { return 2* i} /* 14/} /* 15 */ public class MainClass extends Abs implements MyInterface { /* 16*/ public int number() { return 11 } /* 17 */ public static void main(String args[]) { /* 18 / MainClass 51 = new MainClass() /* 19 */ MainClass s2 = new Sub(16) /* 20 */ System.out.println() /*21*/) /* 22 */ int twice(int x) { return 2 * x} /* 23*/ int ace() { return 1} /* 24 */ String dubble(String s) { return s +s} /* 25/) O 18, 19 O 24. 13 13, 24 O None of the above Question 3 1 pts What effect does the keyword "final" on line nine have? /* 1 */ interface Myinterface { /* 2 */ int number() /* 3*/ } /* 4*/ abstract class Abs { /* 5 */ static int foo = 12 /* 6*/ int number() { return 5} /*7*/ abstract int ace() /* 8*/ } /* 9*/ final class Sub extends MainClass { /* 10 */ Sub(int bar) { foo = bar} /* 11 */ int number() { return 10 } /* 12 / int ace() { return 13 } /* 13 */ int dubble(int i) { return 2* i} /* 14/} /* 15 */ public class MainClass extends Abs implements MyInterface { /* 16*/ public int number() { return 11 } /* 17 */ public static void main(String args[]) { /* 18/ MainClass s1 = new MainClass() /* 19 */ MainClass s2 = new Sub(16) /* 20 */ System.out.println() /* 21/} /* 22 */ int twice(int x) { return 2*x} /* 23*/ int acel) { return 1} /* 24 */ String dubble(String s) { return s + s} /* 25 */ } The class can be extended O The class cannot be extended The class cannot be static The class cannot be abstract
