在Java中,常见的循环语句有for循环、while循环和do-while循环。 until循环语句 在Java中,并没有until循环语句,而是使用while循环来实现相同的功能。until循环是指在条件为真之前一直执行代码块,而while循环是在条件为真时执行代码块。因此,我们可以使用while循环来实现until循环的效果。 实现步骤 下面是实现until循环的...
package com.journaldev.javadowhileloop; public class DoWhileTrueJava { public static void main(String[] args) throws InterruptedException { do { System.out.println("Start Processing inside do while loop"); // look for a file at specific directory // if found, then process it, such as inser...

This loop continues until the condition-expression evaluates to false. Like in a for loop and a while loop, a break statement may be used to exit a do-while loop. 2. Java Do-while Example The following program demonstrates the basic usage of a do-while loop. The program prints the numb...
In this tutorial, we’ll cover the four types of loops in Java: the for loop, enhanced for loop (for-each), while loop and do-while loop. We’ll also cover loop control flow concepts with nested loops, labeled loops, break statement, continue statement, return statement and local ...
Here, you are going to learn about while and do...while loops. Java while loop Java while loop is used to run a specific code until a certain condition is met. The syntax of the while loop is: while (testExpression) { // body of loop } Here, A while loop evaluates the text...
do-while循环总是先执行循环体,然后再计算条件表达式。如果表达式为真,则循环继续。否则,循环结束。对所有的Java循环都一样,条件condition必须是一个布尔表达式。 下面是一个重写的“tick”程序,用来演示do-while循环。它的输出与先前程序的输出相同。 // Demonstrate the do-while loop. ...
Python 中的“For-loop” | | --- | --- | --- | | //让我们初始化一个变量 int I = 3;而(i > 0) {System.out.println("三个 hello ");-我;} | //这是一个迷人的循环for(int I = 0;我<3;i++){控制台。WriteLine(“你好!”);} | #这是一个有趣的循环对于范围(10)内的i:打...
While loop Example 2 count = 5; while(count < 5){//condn is false. So, code in while is not executed. System.out.print(count); count++; }//Nothing is printed to output Do While Loop The difference between a while and a do while is that the code in do while is executed at ...
如果执行如下汇编代码,则表示%dl寄存器中存储的\_do\_not\_unlock\_if_synchronized的值为0,需要执行释放锁的操作。 // 将之前字节码指令执行的结果存储到表达式栈顶, // 由于return不需要返回执行结果,所以不需要设置返回值等信息, // 最终在这里没有生成任何push指令 ...
