Question

Java ---

Write a method to summarise daily tempratures. The details are given as follow.

- The method will receive an array of doubles. Each number in the array represents the temperature of a day.

- If there are less than 10 temperatures recorded, the method will not perform any calculation. Instead, it will print a message "Insufficient data".

- If there are 10 or more temperature recorded, the method will calculate:

-- the average temperature

-- the highest temperature

-- the number of cool days in which the temperatures are 20 or below

-- the number of warm days in which the temperatures are 21 to 30 (inclusive)

-- the number of hot days in which the temperatures are 31 and above.

- Upon completion, the method will print the following:

-- the number of cool days

-- the number of warm days

-- the number of hot days

-- the average temperature

-- the highest temperature

You may assume the array is not empty. You can make use of the following code snippet to write your answer:

public static void getSummary (double [ ] temperatures)

{

//write your code here

}

Answer 1

// I write entire program to check its working...

// you can only copy the function u need...

// it is written according to ur need ...

public class temp{
   public static void main(String args[]){
       double arr[] = {1,2,3,4,5,6,7,8,9,13};
       getSummary(arr);
  
   }
   public static void getSummary (double[] temperatures){
      
       int length = temperatures.length;
       if(length < 10){
           System.out.println("Insufficient data");return ;
       }
       double t,highest = temperatures[0]; // assume first one is highest initially;
       int avg = 0;
       int cool_days = 0,hot_days = 0,warm_days = 0,index; // initial values are 0's
       for(index = 0;index < length ;index ++){
           t = temperatures[index];
           avg += t ;
           if(t > highest) highest = t ;
           if(t <= 20) cool_days ++;
           else if(t <= 30)warm_days ++;
           else hot_days ++;  
       }
       System.out.println(" the number of cool days = "+cool_days+" \n the number of warm days = "+warm_days + " \n the number of hot days = "+hot_days +" \n the average temperature = "+avg/(float)length + "\n the highest temperature = "+highest);

   }
