How to use method overloading for printing different types of array in Java

How to use method overloading for printing different types of array?

This example displays the way of using overloaded method for printing types of array (integer, double and character).

public class MainClass {
   public static void printArray(Integer[] inputArray) {
      for (Integer element : inputArray){
         System.out.printf("%s ", element);
         System.out.println();
      }
   }
   public static void printArray(Double[] inputArray) {
      for (Double element : inputArray){
         System.out.printf("%s ", element);
         System.out.println();
      }
   }
   public static void printArray(Character[] inputArray) {
      for (Character element : inputArray){
         System.out.printf("%s ", element);
         System.out.println();
      }
   }
   public static void main(String args[]) {
      Integer[] integerArray = { 1, 2, 3, 4, 5, 6 };
      Double[] doubleArray = { 1.1, 2.2, 3.3, 4.4, 5.5, 6.6, 7.7 };
      Character[] characterArray = { 'H', 'E', 'L', 'L', 'O' };
      
      System.out.println("Array integerArray contains:");
      printArray(integerArray);
      
      System.out.println("\nArray doubleArray contains:");
      printArray(doubleArray);
      
      System.out.println("\nArray characterArray contains:");
      printArray(characterArray);
   }
}

The above code sample will produce the following result.

Array integerArray contains:
1 
2 
3 
4 
5 
6 

Array doubleArray contains:
1.1 
2.2 
3.3 
4.4 
5.5 
6.6 
7.7 

Array characterArray contains:
H 
E 
L 
L 
O
