SyntaxGet your own Java Server while (condition) { // code block to be executed } In the example below, the code in the loop will run, over and over again, as long as a variable (i) is less than 5:Example int i
Abreakstatement is used to exit the loop in awhile-loopstatement. It is helpful in terminating the loop if a certain condition evaluates during the execution of the loop body. inti=1;while(true)// Cannot exit the loop from here{if(i<=5){System.out.println(i);i++;}else{break;// E...

The Java while loop has two components, a condition and a statements. The statement may be a single statement or a block of statements, and the condition defines the condition that controls the loop. The condition may be any valid Boolean expression. The loop repeats while the given condition...

If you have read the previous chapter, about the for loop, you will discover that a while loop is much the same as a for loop, with statement 1 and statement 3 omitted. The loop in this example uses aforloop to collect the car names from the cars array: ...
刚开始进行while循环的地方while(pt=true){ 这里，如楼上所说，应该是pt==true ，而且楼主的代码获取输入的double的时候为什么不用scan.nextDouble()而是要用scan.nextInt()呢 =

Java Loop With loops, you get to leverage the power in the computer. Working with computers, you quickly learn that they lack any sort of insight to solve problems on their own. On the other hand, the computer is happy to execute the code we specify a million times over, which is its...
