classForLoopExample3 { publicstaticvoidmain(String args[]){ intarr[]={2,11,45,9}; //i starts with 0 as array index starts with 0 too for(inti=0; i<arr.length; i++){ System.out.println(arr[i]); } } } 输出: 1 2 3 4
// 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...

下面是一个完整的示例,演示了如何声明一个长度为5的String数组,并使用for循环为数组赋值: publicclassStringArrayExample{publicstaticvoidmain(String[]args){String[]strArray=newString[5];for(inti=0;i<strArray.length;i++){strArray[i]="String"+i;}// 打印数组中的元素for(Stringstr:strArray){System....
Test.java 文件代码: publicclassTest{publicstaticvoidmain(String[]args){intx=10;while(x<20){System.out.print("value of x :"+x);x++;System.out.print("\n");}}} 以上实例编译运行结果如下: value of x:10value of x:11value of x:12value of x:13value of x:14value of x:15value of...
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) { ...

2. Java For-loop Example In the following program, we are iterating over an array ofintvalues. The array contains 5 elements so the loop will iterate 5 times, once for each value in the array. int[]array=newint[]{0,1,2,3,4};for(inti=0;i<array.length;i++){System.out.format(...
