java - 排序三个命令行整数

Question

你好，我正在尝试编写一个代码，从命令行获取三个整数并将它们排序为最小值、中间值和最大值。我无法弄清楚中间编程。它不会总是正确地对它们进行排序。你能帮我吗？

public class SortInteger{

public static int max3(int a, int b, int c) {
       int max = a;
       if (b > max) max = b;
       if (c > max) max = c;
       return max;
    }

public static int min3(int a, int b, int c) {
       int min = a;
       if (b < min) min = b;
       if (c < min) min = c;
       return min;}

public static int sort(int a, int b, int c){
    int sort = a;
        if (sort > b && sort < c) sort = a;
        else sort = b;
        if (sort > a && sort < c) sort = b;
        else sort =c;
        if (sort > c && sort < a) sort = c;
        else sort =b;
        if (sort > c && sort < b) sort = c;
        else sort = b;
        if (sort > a && sort < b) sort = c;
        else sort = c;
        return sort;
        }


public static void main(String[] args){
    int a= Integer.parseInt(args [0]);
    int b=Integer.parseInt(args[1]);
    int c=Integer.parseInt(args[2]);
    StdOut.println("Min is " + min3(a, b, c));
    StdOut.println("Mid is " + sort(a, b, c));
    StdOut.println("Max is " +  max3(a, b, c));


}

尝试:

public static int mid(int a, int b, int c){
  return a + b + c - max(a,b,c) - min(a,b,c);
}

同样对于 min 和 max 只需使用 Math:

public static int min(int a, int b, int c){
  return Math.min(Math.min(a,b),c);//Replace with Math.max for max.
}
