输入多行，先输入随机整数的个数，再输入相应个数的整数
返回多行，处理后的结果
11 10 20 40 32 67 40 20 89 300 400 15
10 15 20 32 40 67 89 300 400
分别使用HashSet与TreeSet实现
import java.util.ArrayList;
import java.util.Collections;
import java.util.HashSet;
import java.util.Iterator;
import java.util.Scanner;
public class M2 {
public static void main(String[] args) {
Scanner scanner=new Scanner(System.in);
while (scanner.hasNext()) {
HashSet<Integer> aList=new HashSet<Integer>();
int i=scanner.nextInt();
for (int j=0; j< i; j++) {
aList.add(scanner.nextInt());
}
Iterator iterator=aList.iterator();
ArrayList<Integer> n =new ArrayList<Integer>();
for (int j = 0; j < aList.size(); j++) {
n.add((Integer) iterator.next());
}
Collections.sort(n);
for (int m = 0; m < aList.size(); m++) {
System.out.println(n.get(m));
}
}
}
}
while(sc.hasNext())不只一个输入
import java.util.Scanner;
import java.util.TreeSet;
public class M3 {
public static void main(String[] args) {
Scanner scanner=new Scanner(System.in);
while (scanner.hasNext()) {
TreeSet<Integer> aList=new TreeSet<Integer>();
int i=scanner.nextInt();
for (int j=0; j< i; j++) {
aList.add(scanner.nextInt());
}
for (Integer m : aList) {
System.out.println(m);
}
}
}
}
