java比较三个数大小，并输出最大值与最小值

public static void main(String[] args) {
        System.out.println(max(1,2,3));
        System.out.println(max(10,5,9));
        System.out.println(max(55,6,1));
    }

    public static int max(int i, int j, int k) {
        int max = i;
        if (j > max) {
            max = j;
        }
        if (k > max) {
            max = k;
        }
        return max;
    }

2、比较最小值

public static void main(String[] args) {
        System.out.println(min(5,4,3));
        System.out.println(min(6,8,9));
    }

    public static int min(int i, int j, int k) {
        int min = i;
        if (j < min) {
            min = j;
        }
        if (k < min) {
            min = k;
        }
        return min;
    }

3、合并为一个整式

  public static void main(String[] args) {
        System.out.println(min(5,4,3));
        System.out.println(min(6,8,9));
        System.out.println(max(1,2,3));
        System.out.println(max(10,5,9));
        System.out.println(max(55,6,1));
    }
    public static int max(int i, int j, int k) {
        int max = i;
        if (j > max) {
            max = j;
        }
        if (k > max) {
            max = k;
        }
        return max;
    }
    public static int min(int i, int j, int k) {
        int min = i;
        if (j < min) {
            min = j;
        }
        if (k < min) {
            min = k;
        }
        return min;
    }

4、三元符式比较最大值
