Question

java please

Given the following temperature data (no need to worry about which it & months, let's just deal with the numeric values in one 2D array) int[] temps = {{91,62,73 }, {76, 77,88 }, {65,72,55 }, {96,97, 100 }, { 0, 0,0}}; computeTemperatures (temps); display Average Temps(temps); Write the complete JAVA program to compute the average for each month and stores the average for each column/month in the 5th ROW.

Answer 1

Here Iam providing the code and the output for the given problem.

Code:-

public class Main{ public static void main(String [] args) { int temps[][ - {{91,62,73} , {76,77,88} {65,72,55} ,{96,97,100}, {0,0,0} }; /main function //declaration of given 2d array computeTemperatures (temps ) ; //calling the function static void computeTemperatures ( int temps[][]){ int i,j,sum = 0; //below for Loops calculate the average temperatures by column - wise for (i-0; i< 3; i++){ e; sum for(j-0; j<4; j++) sum+temps[j][i]; sum temps[4][i]- sum/4; displayAverageTemps (temps ) ; //calling the display function static void displayAverageTemps ( int temps[][]){ int i,j; System.out.println("This is the final temps 2d array :"); for(i-0;i<5;i++){ for(j-@;j<3;j+++){ System.out.print (temps [i] [j ]+" "); } System.out.print (" \n" ) ; //printing the final 2d array after computing the average temperatures System.out.println("These are the average temperatures"); for (i - 0; i < 3 ;i++){ System.out.print (temps [4] [i] +" "); //printing the average temperatures | }

Code in text format:-

public class Main{
   public static void main(String[] args) { //main function
       int temps[][] = {{91,62,73} ,
       {76,77,88} ,{65,72,55} ,{96,97,100},{0,0,0} }; //declaration of given 2d array
      
       computeTemperatures(temps); //calling the function
   }
  
   static void computeTemperatures(int temps[][]){
   int i,j,sum = 0;
   //below for loops calculate the average temperatures by column-wise
   for(i=0; i< 3; i++){
   sum = 0;
   for(j=0; j<4; j++)
   sum = sum+temps[j][i];
   temps[4][i] = sum/4;
   }
  
   displayAverageTemps(temps); //calling the display function
   }
  
   static void displayAverageTemps(int temps[][]){
   int i,j;
   System.out.println("This is the final temps 2d array :");
   for(i=0;i<5;i++){
   for(j=0;j<3;j++){
   System.out.print(temps[i][j]+" "); //printing the final 2d array after computing the average temperatures
   }
   System.out.print("\n");
   }
   System.out.println("These are the average temperatures");
   for(i = 0; i < 3 ;i++){
   System.out.print(temps[4][i] +" "); //printing the average temperatures
   }
      
   }
}

Output:-

This is the final temps 2d array : 91 62 73 76 77 88 65 72 55 96 97 100 82 77 79 These are the average temperatures 82 77 79
