Question

用java编写一个程序，比较任意三个数，按从小到大的顺序输出，一定要用构造方法。

Answer 1

import java.util.Arrays;
import java.util.Scanner;

public class DataCompare {

public static void main(String[] args) {

int[] ary = new int[3];

Scanner scanner = new Scanner(System.in);

for(int i = 0; i < ary.length; i++){
System.out.print("Please input a digit(Seq: " + (i+1) + "): ");
ary[i] = scanner.nextInt();
}

Arrays.sort(ary);

System.out.print("After sorted by ASC, the numbers are: ");
for(int i = 0; i < ary.length; i++){
System.out.println(ary[i] + "\t");
}

}

}
--------------------------testing
Please input a digit(Seq: 1): 13
Please input a digit(Seq: 2): 25
Please input a digit(Seq: 3): 9
After sorted by ASC, the numbers are: 9
13
25
