Write the definition of a method reverse, whose parameter is an array of integers. the method reverses the elements of the array. the method does not return a value.
if you pass an array of integers arr1 containing the values 2, 4, 6, 8, 10 to reverse, and print out the array after that, the output will be
10, 8, 6, 4, 2

Following are the code in the Java Programming Language.

//declare a function

public void reverse(int arr1[]) {

   int x;  //set integer type variable

   //set integer type variable which stores array length

   int num = arr1.length;  

   //set for loop for reversing an array

   for (int j = 0; j < arr1.length / 2; j++) {

       x = arr1[j];

       arr1[j] = arr1[num - j - 1];

       arr1[num - j - 1] = x;

   }

}
