Problem Description:

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

Solution:

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);
   }
}

Result:

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
