三數比大小

輸入三個數，將三個由大到小做排序

import java.util.Scanner;
 
public class Demo {
 
    public static void main(String[] args) {
 
        Scanner sc = new Scanner(System.in);
 
        int a = sc.nextInt();
        int b = sc.nextInt();
        int c = sc.nextInt();
 
        System.out.println();
 
        if (a >= b) {
            if (b >= c) {
                System.out.printf("%d  >=  %d  >=  %d", a, b, c);
            } else if (a >= c) {
                System.out.printf("%d  >=  %d  >=  %d", a, c, b);
            } else {
                System.out.printf("%d  >=  %d  >=  %d", c, a, b);
            }
        } else {
            if (a >= c) {
                System.out.printf("%d  >=  %d  >=  %d", b, a, c);
            } else if (b >= c) {
                System.out.printf("%d  >=  %d  >=  %d", b, c, a);
            } else {
                System.out.printf("%d  >=  %d  >=  %d", c, b, a);
            }
        }
 
    }
}

另外一種解法：

import java.util.Scanner;
 
public class Demo {
 
    public static void main(String[] args) {
 
        Scanner sc = new Scanner(System.in);
 
        int a = sc.nextInt();
        int b = sc.nextInt();
        int c = sc.nextInt();
 
        System.out.println();
 
        int max = a;
        int min = a;
 
        if (b > max) {
            max = b;
        }
        if (c > max) {
            max = c;
        }
 
        if (b < min) {
            min = b;
        }
        if (c < min) {
            min = c;
        }
 
        System.out.printf("%d  >=  %d  >=  %d", max, a + b + c - max - min, min);
 
    }
}
