Question

Write a JAVA program that prompts a user to enter data for an array. 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.  

EXAMPLE OUTPUT

Enter Integers: (Enter -999 to stop)

Enter Integer: 2

  Enter Integer: 3

Enter Integer: 4

Enter Integer: 5

Enter Integer: -999


Processing the int array.

Total : 14

Average : 4

Highest value : 5

Lowest value : 2

               break;
           }
           a[l]=r;
           l++;
