Question
Write a JAVA program with an array that is initialized with test data. Use any primitive data type of your choice. The program should also have the following methods:
• getTotal. This method should accept a one-dimensional array as its argument and return the total of the values in the array.
• GetAverage. This method should accept a one-dimensional array as its argument and return the average of the values in the array.
• GetHighest. This method should accept a one-dimensional array as its argument and return the highest of the values in the array.
• GetLowest. This method should accept a one-dimensional array as its argument and return the lowest of the values in the array.
Demonstrate each of the methods in the program using the data from the following four one-dimensional arrays.
// Some arrays of various types. int[] iarray = { 2, 1, 9, 7, 3 }; float[] farray = { 3.5F, 4.6F, 1.7F, 8.9F, 2.1F }; double[] darray = { 98.7, 89.2, 55.1, 77.6, 99.9 }; long[] larray = {100, 500, 200, 300, 400 };
Example input and output
Processing the int array.
Total : 22
Average : 4
Highest value : 9
Lowest value : 1
Processing the float array.
Total : 20.800001
Average : 4.1600003
Highest value : 8.9
Lowest value : 1.7
Processing the double array.
Total : 420.5
Average : 84.1
Highest value : 99.9
Lowest value : 55.1
Processing the long array.
Total : 1500
Average : 300
Highest value : 500
Lowest value : 100

return lowest;
