Swapping data in Arrays using Temp variables – Java

What it does: 

A program that swaps data which has been predefined into an array. It uses temp variables to do so. It changes the data at position 0 with the data at position 3. Prints out at the end so the change can be seen.

Code:

public class SwapingDataArrays
{
 public static void main(String[] args)
 {
 String [] names= {"Mary", "Kaye", "Eyup", "Santos"};
 String [] gender = {"Female", "Male", "Male", "Male"};
 int [] age = {12,9,10,24};

//Declaring temp arrays
 String tempName, tempGender;
 int tempAge;


 // assigning temp variables to arrays
 tempName = names[0];

tempGender = gender[0];

tempAge = age[0];


 // Swaping over the data
 names [0] = names[3];

gender[0] = gender[3];

age[0] = age[3];


 //Setting the array to temp variable
 names[3] = tempName;

gender[3] = tempGender;

age[3] = tempAge;

//Print out
 System.out.println(names[0] + " " +names[3]);
 System.out.println(gender[0] + " " +gender[3]);
 System.out.println(age[0] + " " +age[3]);
 }//main
}//class
