D. same as value 1
#
5. The following code displays ___________.
6
double temperature = 50;
if (temperature >= 100)
System.out.println(“too hot”);
else if (temperature <= 40)
System.out.println(“too cold”);

#
6. The “less than or equal to” comparison operator in Java is __________.
A. <<
B. =<

#
7. Analyze the following code fragments that assign a boolean value to the variable even.

even = true;
else
even = false;
Code 2:
even = (number % 2 == 0) ? true: false;
Code 3:
even = number % 2 == 0;

#
14. Analyze the following code.
public class Test {
public static void main(String[] args) {
System.out.println(max(1, 2));
}
9
public static double max(int num1, double num2) {
System.out.println(“max(int, double) is invoked”);
if (num1 > num2)
return num1;
else
return num2;
}
public static double max(double num1, int num2) {
System.out.println(“max(double, int) is invoked”);
if (num1 > num2)
return num1;
else
return num2;
}
}
A. The program runs and prints 2 followed by “max(double, int)” is invoked.
B. The program cannot compile because the compiler cannot determine which max
method should be invoked.
C. The program runs and prints “max(int, double) is invoked” followed by 2.
D. The program runs and prints 2 followed by “max(int, double)” is invoked.
E. The program cannot compile because you cannot have the print statement in a non-
void method.
#
15. Analyze the following code:
public class Test {
public static void main(String[] args) {

return n;
}
public static long xMethod(long n, long l) {
System.out.println(“long, long”);
return n;
}
}
10

list1[0] = 0; list1[1] = 1; list2[2] = 2;
for (int i = 0; i < list2.length; i++)
System.out.print(list2[i] + ” “);
}
}
a. 1 2 3
b. 1 1 1
c. 0 1 2
