如何在Java中随机播放列表
首先，创建一个Integer数组-
Integer[] strArray = new Integer[] { 10, 20, 30, 40, 50, 60, 70, 80, 90, 100 };现在，将其转换为列表-
List<Integer>list = Arrays.asList(strArray);
使用Collections随机播放，如下所示-
Collections.shuffle(list);
示例
import java.util.Arrays;
import java.util.Collections;
import java.util.List;
public class Demo {
public static void main(String args[]) {
Integer[] strArray = new Integer[] { 10, 20, 30, 40, 50, 60, 70, 80, 90, 100 };
List<Integer>list = Arrays.asList(strArray);
System.out.println("List = "+list);
Collections.shuffle(list);
System.out.println("Shuffled List = "+list);
}
}输出结果
List = [10, 20, 30, 40, 50, 60, 70, 80, 90, 100] Shuffled List = [100, 90, 40, 70, 20, 10, 80, 30, 60, 50]
