Note that all expressions in thefor-loopare optional. In case, we do not provide theterminationexpression, we must terminate the loop inside the statements else it can result in aninfinite loop. 2. Java For-loop Example In the following program, we are iterating over an array ofintvalues....
从Java5起,在Java中有了for-each循环,可以用来循环遍历collection和array。For each循环允许你在无需保持传统for循环中的索引,或在使用iterator /ListIterator时无需调用while循环中的hasNext()方法就能遍历collection。Java中,for-each循环简化了任何Collection或array的遍历过程,但并不是每个Java程序员都了解本文将要描述...

for-each循环用于在java中遍历数组或集合。它比简单的for循环更容易使用,因为不需要递增值和使用下标符号。 语法: for(Typevar:array){//code to be executed} Java 示例: publicclassForEachExample{publicstaticvoidmain(String[] args){intarr[] = {12,23,44,56,78};for(inti : arr) { ...
Statement 3 increases a value (i++) each time the code block in the loop has been executed.Another ExampleThis example will only print even values between 0 and 10:Example for (int i = 0; i <= 10; i = i + 2) { System.out.println(i); } Try it Yourself » ...

Forparallel streams, useforEachOrdered()if the order of the elements matters during the iteration. The forEach() method does not guarantee the element ordering to provide the advantages of parallelism. In this example, we are printing all the even numbers from a stream of numbers. ...
public class DoWhileLoopExample { public static void main(String[] args) { int count = 0; do { System.out.println("Count is: " + count); count++; } while (count < 5); } } 4. 增强 for 循环(用于遍历数组或集合) 增强for 循环(也称为 for-each 循环)用于遍历数组或集合中的元素。
