java中从10-100中产生5个不重复的随机数

你要努力啊!这种程序还要来问.这个代码你参考一下吧!多看jdk文档,里面的很多东西包装的很好的.
import java.util.HashSet;

public class Test {
public static void main(String args[]) {
HashSet<Integer> hs = new HashSet<Integer>();
while (true) {
int a = (int)(Math.random() * 100);
if(a >= 10 && a <= 100) {
hs.add(a);
}
if (hs.size() == 5) {
break;
}
}
System.out.println(hs);
}
}
