Java For LoopWhen you know exactly how many times you want to loop through a block of code, use the for loop instead of a while loop:SyntaxGet your own Java Server for (statement 1; statement 2; statement 3) { // code block to be executed }...
Thefor-loopstatement in Java provides a compact way to iterate over the arrays or collection types using a counter variable that is incremented or decremented after each iteration. Programmers often refer to it as thetraditional “for loop”because of the way it repeatedly loops until a particular...

// infinite loop for( ; ; ) { // statement(s) } 用for循环遍历数组(array)的例子: 在这里,我们使用for循环遍历和显示数组里面的每个元素。 classForLoopExample3 { publicstaticvoidmain(String args[]){ intarr[]={2,11,45,9}; //i starts with 0 as array index starts with 0 too for(inti...
这最终会导致死循环条件。因此可见,增量/递减操作的结果必须是能确保在某个时间点上,循环条件的返回值为false,这样程序才可以跳出这个for循环。 下面是另一个for循环的死循环的例子: 1 2 3 4 // infinite loop for( ; ; ) { // statement(s)
do{ //loop-statement}while(expression);II、执行流程 不管三七二十一,先做一次循环体;然后判定表达式的结果 如果结果时true则再执行循环体一次 ,继续判定 直到循环条件(表达式)的结果时false,则终止整个do-while循环 III、注意事项 知道循环终止条件,但是不确定循环次数;do-while的使用场景比较少,适用于循...
The basicforloop was extended in Java 5 to make iteration over arrays and other collections more convenient. This newerforstatement is called theenhanced fororfor-each(because it is called this in other programming languages). I've also heard it called thefor-inloop. ...
这是无限for循环的另一个例子: // 无限循环 for ( ; ; ) { // statement(s) } 1. 2. 3. 4. for循环示例迭代数组 这里我们使用for循环迭代并显示数组元素。 class ForLoopExample3 { public static void main(String args[]){ int arr[]={2,11,45,9}; ...
public class BreakStatement { public static void main(String[] args) { for (int i = 1; i <= 10; i++) { if (i == 5) { break;} System.out.println("Hello, World! " + i);} } } 4.2 continue continue 用于跳过当前循环的剩余部分,直接进入下一次循环。public class ContinueStatement...
title 实现“Java for循环加2” section 创建for循环 ForLoop.start section 对变量加2 AddTwo.process section 打印输出结果 PrintStatement.execute 结尾 通过以上步骤,你可以很容易地实现“Java for循环加2”的功能了。记得在学习过程中多实践,才能更好地掌握知识。希望本文对你有所帮助,加油!
