Develop a Java program for sorting an integer array, floating-point array and character array. Use Generic method for the implementation. Finally print the sorted array. Note: consider the size of the array to be 5.

Here is a Java program that uses a generic method to sort an integer array, a floating-point array, and a character array.

import java.util.Arrays;

public class Main {
    public static void main(String[] args) {
        Integer[] intArray = {2, 4, 3, 1, 5};
        Double[] doubleArray = {1.1, 3.3, 2.2, 5.5, 4.4};
        Character[] charArray = {'b', 'a', 'e', 'd', 'c'};

        System.out.println("Original arrays:");
        printArray(intArray);
        printArray(doubleArray);
        printArray(charArray);

        sortArray(intArray);
        sortArray(doubleArray);
        sortArray(charArray);

        System.out.println("Sorted arrays:");
        printArray(intArray);
        printArray(doubleArray);
        printArray(charArray);
    }

    public static <T extends Comparable<T>> void sortArray(T[] array) {
        Arrays.sort(array);
    }

    public static <T> void printArray(T[] array) {
        for (T element : array) {
            System.out.print(element + " ");
        }
        System.out.println();
    }
}

This program first defines three arrays: an Integer array, a Double array, and a Character array. It then prints the original arrays, sorts them using the sortArray method, and prints the sorted arrays.

The sortArray method is a generic method that takes an array of any type that extends Comparable. It uses the Arrays.sort method to sort the array.

The printArray method is also a generic method that takes an array of any type. It iterates over the array and prints each element, followed by a space. After printing all elements, it prints a newline.
