用java语言获取1--N的不重复随机数 - JAVA

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

public class H {
public static void main(String args[]) {
int N = 10;
List list = new ArrayList();
for (int i = 0; i < N; i++) {
list.add(i + 1);
}
int count = N;
int items[] = new int[N];

for (int i = 0; i < N; i++) {
//
int randomInt = new Random().nextInt(count);
items[i] = list.get(randomInt);
list.remove(randomInt);
count--;
System.out.println(items[i]);
}
}
