What is true about DO statement?
What is true about do statement? Explanation: Do statement checks the condition at the end of the loop. Hence, code gets executed at least once. … Explanation: Break is used with a switch statement to shift control out of switch.
Which are selection statements?
The selection statement means the statements are executed depends – upon a condition. … This statement is also called a decision statement or selection statement because it helps in making decisions about which set of statements are to be executed.
Which of these are selection statements?

Which is the true of a do loop?
The do while loop checks the condition at the end of the loop. This means that the statements inside the loop body will be executed at least once even if the condition is never true. The do while loop is an exit controlled loop, where even if the test condition is false, the loop body will be executed at least once.
Do statements Java?
The Java do-while loop is used to iterate a part of the program repeatedly, until the specified condition is true. If the number of iteration is not fixed and you must have to execute the loop at least once, it is recommended to use a do-while loop. Java do-while loop is called an exit control loop.
What are control statements in Java?
A control statement in java is a statement that determines whether the other statements will be executed or not. It controls the flow of a program. An ‘if’ statement in java determines the sequence of execution between a set of two statements.
Which of the following statement is a loop statement?

What is while loop statement?
A while loop is a control flow statement that allows code to be executed repeatedly based on a given Boolean condition. The while loop can be thought of as a repeating if statement.
DO loop is an iterative statement because it?
Do… Loop is an iterative statement because it: … runs the same block of statements repeatedly.
What is loop in Java?
Introduction. The Java for loop is a control flow statement that iterates a part of the programs multiple times. The Java while loop is a control flow statement that executes a part of the programs repeatedly on the basis of given boolean condition.
What are the 3 types of loops?
Visual Basic has three main types of loops: for..next loops, do loops and while loops.
Which of the following is an conditional statement?
Conditional statements help you to make a decision based on certain conditions. These conditions are specified by a set of conditional statements having boolean expressions which are evaluated to a boolean value true or false.
What is conditional statement in Java?
A conditional statement consists of a condition and a task. … When the condition is true, the application performs the task. The condition portion of a conditional statement is also called an expression.
What are the jump statements in Java?
Java has three types of jumping statements they are break, continue, and return. These statements transfer execution control to another part of the program.
Which loop statements does Java support?
Java provides three repetition statements/looping statements that enable programmers to control the flow of execution by repetitively performing a set of statements as long as the continuation condition remains true. These three looping statements are called for, while, and do…while statements.
