Given:
1 . public class IfTest (
2 . public static void main(string[]args) {
3 . int x = 3;
4 . int y = 1;
5 . if (x = y)
6 . system.out.printIn("Not equal");
7 . else
8 . system.out.printIn("Equal");
9 .}
1 0. )
What is the result?

• A.The output in "Not Equal"
• B.The output is "Equal"
• C.The program executes but does not print a message.
• D.An error at line 5 causes compilation to fall.

Exhibit:
1 . class super {
2 .public int getLength(){return 4;}
3 .}
4 .
5 . public class Sub extends Super {
6 .public long getLength() {return 5;}
7 .
8 . public static void main (String[]args){
9 .super sooper = new Super ();
1 0. Sub sub = new Sub();
1 1. System.out.printIn(
1 2.sooper.getLength()+ "," + sub.getLength()};
1 3.}
1 4. }
What is the output?

• A.4, 5
• B.4, 4
• C.5, 4
• D.5, 5
• E.The code will not compile.

Exhibit:
1 . public class X {
2 . public static void main (String[]args){
3 . int [] a = new int [1]
4 . modify(a);
5 . System.out.printIn(a[0]);
6 .}
7 .
8 . public static void modify (int[] a){
9 .a[0] ++;
1 0.}
1 1. }
What is the result?

• A.The program runs and prints "1"
• B.The program runs but aborts with an exception.
• C.An error "possible undefined variable" at line 9 causes compilation to fail.
• D.The program runs and prints "0"
• E.An error "possible undefined variable" at line 4 causes compilation to fail.

Given:
8 . int index = 1;
9 . boolean[] test = new Boolean[3];
1 0. boolean foo= test [index];
What is the result?

• A.Foo has the value of 0.
• B.Foo has the value of true.
• C.Foo has the value of null.
• D.The code will not compile.
• E.Foo has the value of false.
• F.An exception is thrown.

Which code determines the int value foo closest to, but not greater than, a double value bar?

• A.Int foo = (int) Math.min(bar);
• B.Int foo = (int) Math.round(bar);
• C.Int foo = (int) Math.floor(bar);
• D.Int foo = (int) Math.max(bar);
• E.Int foo = (int) Math.ceil(bar);
• F.Int foo = (int) Math.abs(bar);
