The following example demonstrates how to output arrays of different types (integer, double and character) by overloading the printArray method of the MainClass class:

/*

 MainClass.java
 */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 = { &#39;H&#39;, &#39;E&#39;, &#39;L&#39;, &#39;L&#39;, &#39;O&#39; };
      System.out.println("输出整型数组:");
      printArray(integerArray);
      System.out.println("\n输出双精度型数组:");
      printArray(doubleArray);
      System.out.println("\n输出字符型数组:");
      printArray(characterArray);
   }}

The output result of the above code is:

输出整型数组:
1 
2 
3 
4 
5 
6 
输出双精度型数组:
1.1 
2.2 
3.3 
4.4 
5.5 
6.6 
7.7 
输出字符型数组:
H 
E 
L 
L 
O
