Program Plan Intro

Program plan:

SwapFirstSecond.java

• Create a class named “SwapFirstSecond”.
  • Create a function named “swapFirstHalfSecondHalf()” for swapping the first and second half elements of same array.
    • Declare an integer type variable and assign “first=0”.
    • Declare an integer type variable and assign “second” is equal to “arr.length/2”.
    • Create a temporary variable “temp” for swapping the values in an array.
    • Using “while” loop check whether “first” is less than “arr.length/2”.
      • If the condition is true, follow the below swapping process.
        • The value of “arr[first]” is stored in the temporary variable “tmp”.
        • Then the value of “arr[second]” is stored in the variable “arr[first]”.
        • Finally value of “temp” is stored in the variable “arr[second]”.
  • Create a main function.
    • Declare and initialize the array values.
    • Call the function “swapFirstHalfSecondHalf()”and pass the argument “myValues” to the function for swapping first and second half of an array
    • Using “for” loop, print the new array values.
    • Print and display the newly swapped array values.
