Answer to Question #21947 in Java | JSP | JSF for bebo

Question

Write a program that uses a two-dimensional 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:

a) Method getData: This method reads and stores the data in the two-dimensional array.
b) Method averageHigh: This method calculates and returns the average high temperature of the year.
c) Method averageLow: This method calculates and returns the average low temperature of the year.
d) Method indexHighTemp: This method returns the index of the highest temperature in the array.
e) Method indexLowTemp: This method returns the index of the lowest temperature in the array.


(Note: These methods must all have the appropriate parameters)

Answer 1

public class Temperature {
// Variables

int arr[][];

// Methods
void getData(int arr[][]) {
& this.arr = arr;
}

int indexHighTemp() {
& int high = arr[1][0];
& for (int i = 1; i < 12; i++) {
if (arr[1][i] > high) {
high = arr[1][i];
}
& }
& return high;
}

int indexLowTemp() {
& int low = arr[0][0];
& for (int i = 1; i < 12; i++) {
if (arr[0][i] < low) {
low = arr[0][i];
}
& }
& return low;
}

double averageHigh() {
& double avHigh = arr[1][0];
& for (int i = 1; i < 12; i++) {
avHigh += arr[1][i];
& }
& return avHigh/12;
}

double averageLow() {
& int avLow = arr[0][0];
& for (int i = 1; i < 12; i++) {
avLow += arr[0][i];
& }
& return avLow/12;
}
}
