In Java, the do-while loop is used to execute statements again and again. This loopexecutes at least oncebecause the loop is executed before the condition is checked. It means loopcondition evaluates after executing 至少执行一次,因为该循环是在检查条件之前执行的。 这意味着在执行循环体后评估循环...
condition:循环的条件,只有当条件为真时才会继续执行循环。 下面是一个使用do-while循环判断用户输入是否为正整数的示例代码: importjava.util.Scanner;intnum;do{System.out.print("请输入一个正整数:");Scannerscanner=newScanner(System.in);num=scanner.nextInt();}while(num<=0);System.out.println("输入的...
If the condition proves to be false, the instructions in the code block will not be executed. while (condition) { //Instructions be executed } Example A basic example of the Java while loop. Other supporting code was removed to improve readability and keep the code short. int x = 0; ...
The while loop in Java is a control flow statement that allows code to be executed repeatedly based on a given boolean condition. The loop continues to execute as long as the specified condition evaluates to true. It is particularly useful when the number of iterations is not known beforehand...
The while loop loops through a block of code as long as a specified condition is true: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 ...
The while loop in Java continually executes a block of statements until a particular condition evaluates to true, else the loop terminates.
terminationexpression provides the condition when evaluates tofalse, the loop terminates. incrementexpression is invoked after each iteration; it is perfectly acceptable for this expression to increment or decrement a counter variable. statementsare instructions executed in each iteration of the loop. We ...
The second basic type of loop in Java that I will discuss is the "while loop". A while loop is actually just a conditional that repeats itself as long as the condition stays true. It looks a lot like an if statement. Here take a look: ...
在Java中,"Stop try块自动迭代到下一个循环"这个问题描述的是在使用try-catch语句块时,当try块中的代码发生异常时,程序会自动跳转到catch块进行异常处理,然后继续执行下一个循环。 具体来说,当在for循环中使用try-catch语句块时,如果try块中的代码发生异常,程序会立即跳转到catch块进行异常处理,然后继...
least once, even though condition expression returns false. Otherwise, it’s always better to use a while loop. Java while loop looks cleaner than a do-while loop. That’s all for java do while loop. You should also look intojava for loopandjava continue statement. Reference:Oracle ...
