算法练习 （之八）
1.使用Set存储数据；
package pers.benjamin.example;
import java.util.Random;
import java.util.Scanner;
import java.util.TreeSet;
public class AlgorithmExample8 {
public static void main(String[] args) {
// TODO Auto-generated method stub
Scanner input = new Scanner(System.in);
Random random = new Random();
while (input.hasNext()) {
int num = input.nextInt();
TreeSet
set = new TreeSet
();
for (int i = 0; i < num; i++) {
int current = random.nextInt(1000);
set.add(current);
}
for (Integer i : set) {
System.out.println(i);
}
}
}
}
