in) Įxplain the use of the following Mathematical functions: Input through Scanner Class Scanner in = new Scanner( System. Hence println statement of default case will get executed printing "Value of number is greater than two" to the console. In the example below, value of number is 4 so case 0, case 1 and case 2 are not equal to number. When none of the case values are equal to the expression of switch statement then default case is executed. What is the purpose of default in a switch statement? Explain with the help of an example. do-while loop is an exit-controlled loop. If the condition is true, loop will perform the next iteration otherwise program control will move out of the loop. for and while loops are entry-controlled loops.Īn exit-controlled loop checks the condition after executing its body. Only if the condition is true, the program control enters the body of the loop. There are two types of looping statements in Java:Īn entry-controlled loop checks the condition at the time of entry. Looping statements are used to repeat a single statement or a set of statements as long as the desired condition remains true. We can perform Multiple Branching of control using if-else-if ladder and switch-case statements. In Multiple Branching of control, multiple conditions are tested and then control flow is transferred to that branch (comprising of a particular set of statements) whose condition tests true. We can perform Bi-Directional flow of control using if and if-else statements. In Bi-Directional flow of control, control flow is transferred to one set of statements if the condition is true and to a different set of statements if the condition is false. Control flow can be altered in the following two ways: The statements that enable us to alter the control flow of the program are known as control statements. ![]() But most of the times our programs require to alter this top to bottom control flow based on some condition. By default, the statements of a program are executed from top to bottom in order in which they are written. The order in which the statements of a program are executed is known as control flow. The different types of statements used in Java are: Statements are composed of valid tokens and keywords of the computer language in which they are coded. Statement are instructions which tell the computer what to do. What is meant by statement? Name the different types of statements which are used in Java programming. Write the following statement using switch case construct. Outer loop terminates as m becomes greater than 3, final value of q is 29. Third iteration of inner loop begins, n is incremented to 3. Inner loop restarts from first iteration, n is initialized to 1. Second iteration of outer loop begins, m is incremented to 3. Inner loop terminates as n becomes greater than m. Second iteration of inner loop begins, n is incremented to 2. ![]() Assuming initial value of all variables to be zero.įirst iteration of outer loop begins, m is initialized to 2.įirst iteration of inner loop begins, n is initialized to 1.
