按升序输出数字（if - else）java

Question

告诉我缺少什么？两个值排序正确，但平均值不正确:(

package com.Star;

public class Main {

    public static void main(String[] args) {

        int a = 89;
        int b = 96;
        int c = 88;

        if (a < b & a < c)
            System.out.println(a + " " + b + " " + c);

        if (b < c & b < a)
            System.out.println(b + " " + c + " " + a);

        if (c < a & c < b)
            System.out.println(c + " " + b + " " + a);

    }
}

这不是正确的方法，但如果将 & 替换为 &&，您可以获得部分正确的代码，因为您必须检查 3 个元素的 6 种排列 (nPr)。使用数组并应用排序方法。

 public static void main(String[] args) {

        int a = 89;
        int b = 96;
        int c = 88;

        if (a < b && b < c)
            System.out.println(a + " " + b + " " + c);
        else if (a < c && c < b)
            System.out.println(a + " " + c + " " + b);
        else if (b < a && a < c)
            System.out.println(b + " " + a + " " + c);
        else if (b < c && c < a)
            System.out.println(b + " " + c + " " + a);
        else if (c < a && a < b)
            System.out.println(c + " " + a + " " + b);
        else if (c < b && b < a)
            System.out.println(c + " " + b + " " + a);

        }
