Question

Write a method that reverses the sequence of elements in an array. For example, if you call the method with the array 1, 4, 9, 16, 9, 7, 4, 9, 11, then the array is changed to 11, 9, 4, 7, 9, 16, 9, 4, 1. Use one or more loops in your solution (do not use the Array Reverse method).

Answer 1

Answer:

The method written in Java is as follows:

   public static void ArrayReverse(int myarray[]){

       for(int index = myarray.length-1; index>=0;index--)

           System.out.print(myarray[index]+" ");

}

Explanation:

This line defines the method

   public static void ArrayReverse(int myarray[]){

This line iterates through the array from highest to least index

       for(int index = myarray.length-1; index>=0;index--)

This prints the array elements in reverse

           System.out.print(myarray[index]+" ");

}

To call the method from the main, use the following:

ArrayReverse(myarr);

However, myarr must be declared and populated as an integer array before the method is called
