A for loop is also called a definite loop

• True

• False

The for loop provides a complicated way to iterate over a range of values.

• True

• False

Which statement will produce the output: 2, 4, 6, 8, 10?

• for (int i = 0; i < 10; i += 2) {

  System.out.print(i + " ");

  }

• for (int i = 1; i < 10; i += 2) {

  System.out.print(i + " ");

  }

• for (int i = 0; i < 8; i += 2) {

  System.out.print(i + " ");

  }

• for (int i = 2; i <= 10; i += 2) {

  System.out.print(i + " ");

  }

Given:

for(int i = 0; i > 10; i++){ }

What type of variable is i?

• Global

• Static

• Member

• Local

Which two operators cannot be used as the conditional expression in a for loop?

• <

• !<

• !>

• ==

• !=

Which is not a looping statement in Java?

• for

• do-while

• switch

• while

Which of the two are pre-test loops?

• for

• while

• do-while

• forEach

What is the output?

• 1 5 25 125

• No output.

• 1 5 25 125 175

• 5 25 125

A pre-test loop evaluates the condition prior to execution of the loop.

• True

• False

Which statement is NOT true about do-while loops?

• The number of times a do-while loop is executed is dependent upon the value of the counter variable.

• Statements in the loop are executed once until the condition becomes false.

• Statements in the loop are executed repeatedly until the condition becomes false.

• Statements in the loop are executed once initially, and then the condition is evaluated.
