5. What is the printout of the following switch statement?
char ch = 'a';
switch (ch) {
case 'a':
case 'A':
System.out.print(ch); break;
case 'b':
case 'B':
System.out.print(ch); break;
case 'c':
case 'C':
System.out.print(ch); break;
case 'd':
case 'D':
System.out.print(ch);
}
a. ab
b. a
c. aa
d. abc
e. abcd
6. What is x after evaluating
x = (2 > 3) ? 2 : 3;
a. 5
b. 2
c. 3
d. 4
7. Analyze the following code.
int x = 0;
if (x > 0);
{
System.out.println("x");
}
a. The value of variable x is always printed.
b. The symbol x is always printed twice.
c. The symbol x is always printed.
d. Nothing is printed because x > 0 is false.
8. To declare a constant MAX_LENGTH inside a method with value 99.98, you write
a. final double MAX_LENGTH = 99.98;
b. double MAX_LENGTH = 99.98;
c. final MAX_LENGTH = 99.98;
d. final float MAX_LENGTH = 99.98;

The printout of the switch statement will be b. "a". The value after the : is assigned to x, which is c. 3. D. Nothing is printed because x > 0 is false. a. final double MAX_LENGTH = 99.98;.

5. The printout of the switch statement will be "a". The variable ch is set to 'a', and there is a case statement for both 'a' and 'A'. Since there is no explicit break statement after the case 'a', the program will continue executing the next case, which is 'A'. The print statement System.out.print(ch); will be executed, resulting in the output a. "a".

6. The value of x after evaluating x = (2 > 3) ? 2 : 3; will be 3. In the ternary operator (2 > 3) ? 2 : 3, the condition (2 > 3) evaluates to false, so the value after the : is assigned to x, which is C. 3.

7. D. Nothing is printed because x > 0 is false. The code if (x > 0); contains a semicolon immediately after the closing parenthesis of the if statement. This creates an empty statement that does nothing. The subsequent block {System.out.println("x");} is not part of the if statement and will be executed regardless of the condition. Therefore, "x" will not be printed.

8. To declare a constant MAX_LENGTH inside a method with value 99.98, the correct syntax is: a. final double MAX_LENGTH = 99.98;. The keyword final is used to declare a constant variable, and the data type double is specified to indicate the type of the constant.
