The switch statement allows us to execute a block of code among many alternatives.
#Do while loop switch case java how to#
Right now I dont know how to prompt user to input code again to continue the loop, but I have typed in a few lines to prompt the code and it works as intended, but Im sure this is not the most efficient way of doing it?Īnd Im planning to break the loop once user entered the last input/entered an invalid codeĬase 'F' : ("Total Foundation student = ") So I've tried using the for loop method, thanks to Andreas for giving an example :), and it worked! TotalCash = foundationCash + diplomaCash + bachelorCash + masterCash + phdCash //here i want to calculate all the input entered You could also display the name of the month. } while (levelCode < 5) //i dont know what to put here in order to loop the switch case The switch statement evaluates its expression, then executes all statements that follow the matching case label. Here is what I have worked on, there are also notes. Is there a simple way to have the switch statement continually loop until the user gives the appropriate input That is, if the user replies with a value that is not defined by the code, it will run the default case and the code ends. I am fairly a beginner and have only learn java for a few weeks, any suggestion is very appreciated. Then I want to sum all the cash received by each student level. In this tutorial we will discuss do-while loop in java. In a do-while loop, the body of the loop is executed at least one time, whereas in a while loop, the loop may never execute if the loop condition is false.
We can use break statement with label to get out of nested loops or. Java while loop is used to run a specific code until a certain condition is met.I'm currently working on the code that will prompt student level type in code (switch case), and to determine the amount of cash for each type of student will receive. break statement in java can be used to get out of the loop such as for loop, while loop and do-while loop. However, it checks its condition at the bottom of the loop, not the top. Here, you are going to learn about while and do.while loops. Continue statement inside a Do While loop causes the program control to skip the statements below it and go to the beginning of the loop. The Java do while loop, like the while loop, has a condition which terminates it. In the previous tutorial, you learned about Java for loop. It's just a simple example you can achieve much more with loops.
For example, if you want to show a message 100 times, then you can use a loop. In computer programming, loops are used to repeat a block of code. A break can occur inside an if statement, but only if the if statement is nested inside a loop or inside a switch statement.
