Question 2. Question : (TCOs 1–8) What is the printout of the following code?

double x = 5.5;

int y = (int)x;

System.out.println("x is " + x + " and y is " + y);

x is 5.5 and y is 5.0

x is 5.5 and y is 5

x is 5 and y is 6

x is 6 and y is 6

x is 6.0 and y is 6.0

Question 3. Question : (TCOs 1–8) What is the value of (double)(5/2)?

10

Illegal expression

Question 5. Question : (TCOs 1–8) What is y after the following switch statement is executed?

x = 3;

switch (x + 3) {

Question 6. Question : (TCOs 1–8) Analyze the following statement.

double sum = 0;

for (double d = 0; d<10;) {

d += 0.1;

sum += sum + d;

}

The program compiles and runs fine.

The program runs in an infinite loop because d<10 would always be true.

The program has a compile error because the control variable in the for loop cannot be of the double type.

The program has a compile error because the adjustment is missing in the for

loop.

Question 7. Question : (TCOs 1–8) What is the value in count after the following loop is executed?

int count = 0;

do {

System.out.println("Welcome to Java");

between 'a' and 'z'.

between 'b' and 'y'.

Question 9. Question : (Tricky) What is the output of the following code?

public class Test {

public static void main(String[ ] args) {

int[ ] x = {120, 200, 016};

for (int i = 0; i < x.length; i++)

System.out.print(x[i] + " ");

}

}

120 200 16

120 200 20

120 200 14

016 is a compile error. It should be written as 16.

Question 10. Question : Analyze the following code.

public class Test {

public static void main(String[ ] args) {

int[ ] x = new int[5];

int i;

for (i = 0; i < x.length; i++)

x[i] = i;

System.out.println(x[i]);

}

}

The program displays 4.

The program displays 0 1 2 3 4.

The program has a runtime error because the last statement in the main method causes ArrayIndexOutOfBoundsException.

The program has a compile error because i is not defined in the last statement in the main method.
