Java中的循环有两种主要形式：while{} 和 do{}while，它们的主要区别如下：while{} 循环：工作原理：先判断条件表达式是否为真，如果条件为真，则执行循环体内的代码块；如果条件为假，则跳过循环体，继续执行循环之后的代码。特点：条件满足时才执行循环体，因此可能一次都不执行。do{}while 循环：工作...
The while loop first checks the condition, and then decides what to do. 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 ...
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 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 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...
Java是一种常用的编程语言,它被广泛应用于各种软件开发领域。下面是关于使用多个条件语句、while循环、for循环和if语句的问题的答案: 1. 多个条件语句:多个条件语句是指在程序中需要根据不...
