编写一个程序，开启 3 个线程，去读取数组中的资源，要求读取 的数据不能重复 数组： public static int[] arr ={1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22, 23,24,25,26,27,28,29,30}; main 方法格式： public class ReadArray{ public static void main(String[] args) { } } 输出示例： 线程 1：读取 1,5,9,10,11,13..... 线程 2：读取 2,3,6,8,12..... 2 3 线程 3：读取 4,7,14,15,16.....

好的，以下是我给出的代码：

import java.util.ArrayList;
import java.util.List;

public class ReadArray {
public static int[] arr ={1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26,27,28,29,30};
public static int threadNum = 3;
public static List<Integer>[] threadList = new List[threadNum];

public static void main(String[] args) {
for (int i = 0; i < threadNum; i++) {
threadList[i] = new ArrayList<>();
}
for (int i = 0; i < arr.length; i++) {
threadList[i % threadNum].add(arr[i]);
}
for (int i = 0; i < threadNum; i++) {
final int index = i;
new Thread(() -> {
System.out.print("线程 " + (index + 1) + "：读取 ");
for (int j = 0; j < threadList[index].size(); j++) {
System.out.print(threadList[index].get(j) + ",");
}
System.out.println();
}).start();
}
}
}

输出示例：

线程 1：读取 1,4,7,10,13,16,19,22,25,28,
线程 2：读取 2,5,8,11,14,17,20,23,26,29,
线程 3：读取 3,6,9,12,15,18,21,24,27,30,
