Give:

What value should replacekkin line x to cause jj = 5 to be output?

• A. -1
• B. 1
• C. 5
• D. 8
• E. 11

Answer: E

Explanation: We need to get jj to 5. It is initially set to 0. So we need to go through the for loop 5 times. The for loops ends when ii > 6 and ii decreases for every loop. So we need to initially set ii to 11. We set kk to 11.

NEW QUESTION 3
Given:
public class MyClass {
public static void main(String[] args) {
while (int ii = 0; ii < 2) {
ii++;
System.out.println("ii = " + ii);
}
}
}
What is the result?

• A. ii = 1 ii = 2
• B. Compilation fails
• C. The program prints nothing
• D. The program goes into an infinite loop with no output
• E. The program goes to an infinite loop outputting: ii =1ii = 1

Answer: B

Explanation: The while statement is incorrect. It has the syntax of a for statement.
The while statement continually executes a block of statements while a particular condition is true. Its syntax can be expressed as:
while (expression) { statement(s)
}
The while statement evaluates expression, which must return a boolean value. If the expression evaluates to true, the while statement executes the statement(s) in the while block. The while statement continues testing the expression and executing its block until the expression evaluates to false.

Given the code fragment:
/1. ArrayList<Integer> list = new ArrayList<>(1);
/2. list.add(1001);
/3. list.add(1002);
/4. System.out.println(list.get(list.size())); What is the result?

Answer: C

Explanation: The code compiles fine.
At runtime an IndexOutOfBoundsException is thrown when the second list item is added.

NEW QUESTION 10
Given the following code:

What will make this code compile and run?

• A. Change line 2 to the following: Publicint price
• B. Change line 4 to the following: int price = new simple ();
• C. Change line 4 to the following: Float price = new simple ();
• D. Change line 5 to the following: Price = 4f;
• E. Change line 5 to the following: price.price = 4;
• F. Change line 5to the following: Price = (float) 4:
• G. Change line 5 to the following: Price = (Simple) 4;
• H. The code compiles and runs properly; no changes are necessary

Answer: E

Explanation: price.price =4; is correct, not price=4;
The attribute price of the instance must be set, not the instance itself.

NEW QUESTION 11
Given:

This class is poorly encapsulated. You need to change the circle class to compute and return the area instead.
What three modifications are necessary to ensurethat the class is being properly encapsulated?

• A. Change the access modifier of the setradius () method to private
• B. Change the getArea () method public double getArea () { return area; }
• C. When the radius is set in the Circle constructor and the setRadius () method, recomputed the area and store it into the area field
• D. Change the getRadius () method: public double getRadius () {area = Math.PI * radius * radius; return radius;}

Answer: BCD

NEW QUESTION 13
Given:

Which two are possible outputs?

• A. Option A
• B. Option B
• C. Option C
• D. Option D

Answer: AD

Explanation: The first println statement, System.out.println("Before if clause");, will always run.
If Math.Random() > 0.5 then there is an exception. The exception message is displayed and the program terminates.
If Math.Random() > 0.5 is false, then the second println statement runs as well.

NEW QUESTION 18
Given the code fragment:
Int [] [] array = {{0}, {0, 1}, {0, 2, 4}, {0, 3, 6, 9}, {0, 4, 8, 12, 16}};
Systemout.printIn(array [4] [1]);
System.out.printIn (array) [1] [4]); What is the result?

• A. 4Null
• B. Null 4
• C. An IllegalArgumentException is thrown at run time
• D. 4An ArrayIndexOutOfBoundException is thrown at run time

Answer: D

Explanation: The first println statement, System.out.println(array [4][1]);, works fine. It selects the element/array with index 4, {0, 4, 8, 12, 16},and from this array it selects the element with index 1, 4. Output: 4
The second println statement, System.out.println(array) [1][4]);, fails. It selects the array/element with index 1, {0, 1}, and from this array it try to select the element with index
4. This causes an exception.
Output: 4
Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: 4
