Java Control Flow Statements Quiz

What is the purpose of control statements in Java?

• To perform mathematical calculations

• To create objects

• To declare variables

• To control the flow of execution in a program

Which control statement is used to execute a block of code only if a certain condition is true?

• switch-case

• for loop

• if-else

• do-while loop

Which loop is guaranteed to execute at least once?

• while loop

• do-while loop

• if-else loop

Which statement is used to terminate the current iteration of a loop and continue with the next iteration?

• break

• return

• continue

• exit

Which control statement is used to execute different code blocks based on the value of an expression?

• switch-case

• if-else

• for loop

• while loop

What is the purpose of the "default" case in a switch statement?

• It specifies the default value of the expression.

• It is used to compare the value of the expression.

What is the purpose of the "return" statement in a method?

• To declare a variable

• if-else

• switch-case

• for loop

• do-while loop

In a switch-case statement, what happens if there is no "break" statement after a case block?

• The program will not compile.

• Runtime error.

• The next case block will be executed regardless of the condition.

• The program will enter in an infinite loop.

Which loop is suitable when you want to execute the loop body at least once?

• for loop
