ArrayMethodDemo

Program plan:

ArrayMethodDemo.java

• Create a class named “ArrayMethodDemo”. Inside the class,
  • Define the “main ()” method.
    • Create and define the array.
    • Declare and define the required variable and methods.
  • Define the method “display ()”
    • Display the numbers present in the array.
  • Define the method “displayReverse ()”
    • Display the numbers present in the array in the reverse order.
  • Define the method “displaySum ()”
    • Define the required variables.
    • Use loop to iterate and compute the sum of the array elements.
    • Display the sum.
  • Define the method “displayLessThan ()”
    • Loop that iterates for the array elements present.
    • Use condition to validate the values of the array and limit.
    • Display the numbers less than the limit value
  • Define the method “displayHigherThanAverage ()”
    • Declare and define the required variables.
    • Loop that iterates to compute sum of the array elements.
    • Compute the average.
    • Display the average.
    • Loop that iterates for the array elements present.
    • Use condition to validate the values of the array and average.
    • Display the numbers greater than average.
