Program Plan Intro

Generic linear search

Program Plan:

• Define the class named “Exercise19_04”.
  • Define the generic method named “linearSearch()” which passes array list and key as arguments.
    • Using “for” loop, check the list values equal to key value.
      • If the condition is true, return position of the key value.
      • Otherwise, return “-1” to calling function.
  • Define the main method.
    • Declare and initialize an array “arr[]” in type of integer.
    • Call the generic method “linearSearch()” with array and key elements. Print the resultant positions on screen.
