如何打印三角形的数量然后打印它的最小周长？

问题描述：

import java.util.Scanner; 
    public class project { 
    public static void main(String[]args){ 
    Scanner input = new Scanner(System.in); 

// to scan the values 

    int N ; 

// numbers of lines 

    double side1,side2,side3; ` 




    double minimum = 1000; 

// to keep the minimum value 

     double sum = 0; 

// to keep calculated values 

      int which_one = 0 ; 

    System.out.println("How many triangles do you have?"); 
    N = input.nextInt();   

// how many lines 

    System.out.println("Please, insert lengths of the " 
      + "sides of these triangles (3 real numbers per line):"); 

      for (int i = 0; i < N ; i++){ 

// loop for taking the value from the user 


    side1 = input.nextDouble();   // input of side1 
    side2 = input.nextDouble();   // input of side2 
    side3 = input.nextDouble();   // input of side3 
    sum = side1 + side2 + side3; 


    if (sum < minimum) minimum = sum; 
     which_one = N+1; 

      } 

     System.out.printf("Triangle no."+ which_one 
       + " has the minimum perimeter which is %.1f%n "+minimum);   
} 
}

这里有问题吗？你的代码是否工作？你要求我们做什么？ –

欢迎来到Stack Overflow！看起来你正在寻求作业帮助。虽然我们本身没有任何问题，但请观察这些[应做和不应该]（http://meta.stackoverflow.com/questions/334822/how-do-i-ask-and-answer-homework-questions/338845＃338845），并相应地编辑您的问题。 –

答

您的错误在这一行。我已经修正它到它应该是什么：

System.out.printf("Triangle no." + which_one + 
    " has the minimum perimeter which is %.1f\n " , minimum);

我minimum与之前更换了+“”让minimum被作为格式说明%.1f值提供。
