这问题确实不难,多看看书上的
import java.util.Arrays;
import java.util.Scanner;
public class Test {
public static void main(String[] args) {
int i = 3;
int[] list = new int[3];
System.out.println("please Please enter three numbers:");
for (int j = 0; j < i; j++) {
Scanner sc = new Scanner(System.in);
String t = sc.next();
list[j] = Integer.parseInt(t);
}
Arrays.sort(list);
System.out.println("The numbers in sorted order are：");
for (int k :list) {
System.out.println(k);
}
}
}
