An if statement in the middle of the while loop checks for the exit condition. If the exit condition is true, the code calls "break" which exits the while loop immediately: // suppose we have a variable "frog"
The while loop has a similar counterpartcalled the do while loop. Syntax Below is the general code for creating a while loop. 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 execu...

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 ...
Hello again... next code I stuck and can’t find out what’s wrong is import java.util.Scanner; public class Main { public static void main(String[] args) {
for(int x=1;x<=10;x++) { System.out.println("HelloWorld"); } } } Code: 请在控制台输出数据1-10 class ForDemo2 { public static void main(String[] args) { //原始做法 System.out.println(1); System.out.println(2); System.out.println(3); ...
Besides the while-loop for Java presented here and the do-while-loop also taken up, there is also the for-loop. This resembles the Java while-loop at first sight, since it too repeats a code until the defined termination condition becomes “false”. Unlike the while-loop, however, the ...
STATEMENT -> DO STATEMENT WHILE LP TEST RP SEMI 1. 2. 其中,WHILE , DO 对应的就是while 和 do 两个关键字, TEST对应while后面的循环条件。根据语法表达式,我们可以构造对应的语法执行树,在codeTreeBuilder.java中,添加如下代码: public ICodeNode buildCodeTree(int production, String text) { ...
