Java Iteration

The while() loop statement is one of the ways to do iteration in programming. In a while() loop, where should the loop condition be placed?

• At the beginning of the loop body
  

• At the end of the loop body

• After the loop body

• Before the loop body

The do-while() loop statement is another way also to do iteration in programming. In a do-while() loop, where should the loop condition be placed?

• At the beginning of the loop body

• At the end of the loop body

• After the loop body

• Before the loop body

How does the do-while() loop different from the while() loop?

• The do-while() loop is not supported in Java

• The do-while() loop is executes at least once

• The while() loop must have a condition to start executing

• The do-while() loop has a different syntax

Another way to do iteration in programming is by using a for() loop statement which is best to use when the number of iterations is known. When using a traditional for() loop, what is the order of execution of the loop sections?

• Condition; Initialization; Increment/decrement

• Condition; Increment/decrement; Initialization

• Initialization; Condition; Increment/decrement

• Initialization; Increment/decrement; Condition;

The continue statement is used to change the sequence of execution of code in Java. What does the continue statement do in a loop?

• Exits the loop entirely

• Skips the current iteration and moves to the next one

• Repeats the current iteration

• Stops the loop from further execution

The break statement is also used to change the sequence of execution of code in Java. What does the break statement do in a loop?

• Exits the loop entirely

• Skips the current iteration and moves to the next one

• Repeats the current iteration

• Stops the loop from further execution

What loop statement is the best suitable to use for creating a program that continuously asks the user to enter a character until the character entered is 'x' or 'X'?

• while() loop

• do-while() loop

• for() loop

• Either while(), do-while(), or for() loop

What loop statement is the best suitable to use for creating a program that displays "Hello World" a hundred times?

• while() loop

• do-while() loop

• for() loop

• Either while(), do-while(), or for() loop

What loop statement can be used for creating a program that diplays the digit of the number 63742 in reverse order?

• while() loop

• do-while() loop

• for() loop

• Either while(), do-while(), or for() loop
