![In JAVA
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.
(These methods must all have the appropriate parameters.)
