FINAL EXAM

In Java, which loop construct is used to execute a block of code repeatedly as long as a condition is true?

• for loop
• while loop
• do-while loop
• switch loop

What is the minimum number of iterations in a do-while loop?

• 0
• 1
• 2
• It depends on the condition.

How do you terminate a loop prematurely in Java?

• Using the "break" statement.
• Using the "end" statement.
• Using the "terminate" keyword.
• By setting the loop condition to false.

What is the purpose of the "continue" statement in Java looping?

• To terminate the loop.
• To skip the remaining code in the loop and proceed to the next iteration.
• To restart the loop from the beginning.
• To execute the loop infinitely.

In Java, which loop construct is best suited for iterating over arrays or collections?

• for loop
• while loop
• do-while loop
• enhanced for loop (for-each loop)

What will be the output of the following code snippet? int x = 1; while (x <= 5) { System.out.print(x + " "); x++; }

• 1 2 3 4 5
• 5 4 3 2 1
• 1 1 1 1 1
• 2 3 4 5

Which loop construct in Java ensures that the loop body is executed at least once?

• for loop
• while loop
• do-while loop
• enhanced for loop

What is the purpose of the "for-each" loop (enhanced for loop) in Java?

• To execute the loop for a fixed number of times.
• To loop through a collection or array without using an index.
• To iterate over characters in a string.
• To create a nested loop.

What is an infinite loop in Java?

• A loop that executes exactly once.
• A loop that has no loop variable.
• A loop that executes forever without terminating.
• A loop that contains only the "continue" statement.

In Java, how do you create a nested loop?

• By using multiple loop variables in a single loop construct.
• By placing one loop inside the body of another loop.
• By using the "goto" statement.
• By setting the loop condition to a boolean value.
