Question

Write a program that uses a 2-D array to store the highest and lowest temperatures for each month of the year. The program should output the average high, average low, and highest and lowest temperatures of the year. Your program must consist of the following methods with their appropriate parameters:

import java.util.*;

public static void main(String[] args){

int infoArray[][]=getData();

int avgArray[][]=average(infoArray);

System.out.println("Data set - Highs: 87,99,100,102,101,97,97,93,99,94,98,92.");

System.out.println("Average High: "+avgArray[0][0]);

System.out.println("Average Low: "+avgArray[1][0]);

System.out.println("Highest Temperature: "+tempArray[0][0]);

}

public static int[][] average(int x[][]){

int avgH = 0;

int avgL = 0;

//loop to find avg high

for(int i=0;i<x[0].length;i++){

}

//loop to find avg low

for(int h=0;h<x[1].length;h++){

}

avgL=avgL/x[1].length;

int avgData[][] = {{avgH},{avgL}};

return avgData;

}

public static int[][] temps(int x[][]){

//high temp

int ht = 0;

int lt = 100;

for(int t=0;t<x[0].length;t++){

if(x[0][t]>ht){

//low temp
