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：工作原理：
Test.java 文件代码: publicclassTest{publicstaticvoidmain(String[]args){int[]numbers={10,20,30,40,50};for(intx:numbers){System.out.print(x);System.out.print(",");}System.out.print("\n");String[]names={"James","Larry","Tom","Lacy"};for(Stringname:names){System.out.print(name);...
The difference between while and do-while in Java In addition to the while-loop in Java, there is also the do-while-loop. This not only has a similar name, but also works almost exactly like the while-loop. The main difference is that the head-controlled while-loop checks the terminat...
Java:使用while-loop更改行的顺序 Java中使用while循环可以改变行的顺序。while循环是一种迭代结构,它会重复执行一段代码块,直到指定的条件不再满足为止。 在使用while循环改变行的顺序时,可以通过定义一个计数器变量来控制循环的次数。通过递增或递减计数器的值,可以改变行的顺序。 以下是一个示例代码: 代码语言:txt...

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...

The while loop in Java continually executes a block of statements until a particular condition evaluates to true, else the loop terminates.
do { statement(s) } while (expression); The difference between do-while and while is that do-while evaluates its expression at the bottom of the loop instead of the top. Therefore, the statements within the do block are always executed at least once, as shown in the following DoWhileDem...
This prints 2 on the screen and the value of i is increased to 3. This process goes on until i becomes 6. Then, the test expression i <= 5 will be false and the loop terminates. do...while loop The do..while loop is similar to the while loop with one important difference. The...
