You can loop through the array elements with the for loop, and use the length property to specify how many times the loop should run.The following example outputs all elements in the cars array:ExampleGet your own Java Server String[] cars = {"Volvo", "BMW", "Ford", "Mazda"}; for ...
package com.nichagil.test.forloop; import java.util.ArrayList; import java.util.List; public class ForTester { public static void main(String[] args) { List<String> list = new ArrayList<String>(); list.add("a"); for (String s : list) { list.remove(s); System.out.println(s); }...

1、使用for循环进行遍历,直接上代码吧: /** * 遍历JSONArray */privatestaticvoidLoopJSONArray(){//颜色数组字符串StringcolorStr="[{'name':'刘德华','age':28,'sex':'男'},"+"{'name':'张学友','age':29,'sex':'男'}]";//转化为数组JSONArrayjsonArr=JSONArray.fromObject(colorStr);for(int...
publicstaticbooleanLoop(String[] arr, String targetValue) {for(String s: arr){if(s.equals(targetValue))returntrue; }returnfalse; } 方法4:Arrays.binarySearch() ,只能用于有序数组,当数组存储数据很多时推荐此方法。 可以通过计算 long time=System.nanoTime() 计算一下时间复杂度。
In Java, we can also loop through each element of the array. For example, Example: Using For Loop java class Main { public static void main(String[] args) { int[] age = {1, 3, 5, 7}; System.out.println("Using for Loop:"); for(int i = 0; i < age.length; i++) { ...
Similar to the single-dimensional array, we can also copy the 2-dimensional array using the for loop. For example, import java.util.Arrays; class Main { public static void main(String[] args) { int[][] source = { {1, 2, 3, 4}, {5, 6}, {0, 2, 42, -4, 5} }; int[][...

You can loop through the array elements with theforloop. The following example outputs all elements in thecarsarray: Example // Create an array of strings string cars[5] = {"Volvo","BMW","Ford","Mazda","Tesla"}; // Loop through strings ...
