Use Overloaded Methods to Print Array of Different Types in Java

In method overloading, the class can have multiple methods with the same name but the parameter list of the methods should not be the same.

Overloaded methods can be used to print an array of different types in Java by making sure that the parameter list of the methods contains different types of arrays that can be printed by the method.

A program that demonstrates this is given as follows −

Example

 Live Demo

public class Demo {
   public static void arrPrint(Integer[] arr) {
      System.out.print("\nThe Integer array is: ");
      for (Integer i : arr)
         System.out.print(i + " ");
   }
   public static void arrPrint(Character[] arr) {
      System.out.print("\nThe Character array is: ");
      for (Character i : arr)
         System.out.print(i + " ");
   }
   public static void arrPrint(String[] arr) {
      System.out.print("\nThe String array is: ");
      for (String i : arr)
         System.out.print(i + " ");
   }
   public static void arrPrint(Double[] arr) {
      System.out.print("\nThe Double array is: ");
      for (Double i : arr)
         System.out.print(i + " ");
   }
   public static void main(String args[]) {
      Integer[] iarr = { 8, 1, 5, 3, 9 };
      Character[] carr = { 'A', 'B', 'C', 'D', 'E' };
      String[] sarr = { "Jane", "Amy", "John", "Tim", "Sara" };
      Double[] darr = { 7.3, 5.9, 2.5, 3.7, 1.4 };
      arrPrint(iarr);
      arrPrint(carr);
      arrPrint(sarr);
      arrPrint(darr);
   }
}

Output

The Integer array is: 8 1 5 3 9
The Character array is: A B C D E
The String array is: Jane Amy John Tim Sara
The Double array is: 7.3 5.9 2.5 3.7 1.4
