printing array reference variable on console

Question

what does the output means... if we print 'intarray' we get some hash code... & same is with 'floatarray' but if we print 'chararray' we doesn't get anything what does the folowing data means?????

class Test
{
    public static void main(String []aeg)
    {
        int []intarray = new int[5];
        char []chararray = new char[5];
        float []floatarray = new float[5];
        System.out.println(intarray);
        System.out.println(chararray);
        System.out.println(floatarray);
    }
 }

Output starts here

after printing on the console we get following output....

      F:\Mehnat\my sc\By me\ArrayList\2\2>javac Test.java
      F:\Mehnat\my sc\By me\ArrayList\2\2>java Test
      [I@546da8eb

      [F@6b6d079a

Output ends here

Printing an array of characters tries to print the array's content as a string (one character at a time). Your new array is filled with null characters which aren't printed. Try to fill it with something and check again:

chararray[0] = 'H';
chararray[1] = 'e';
chararray[2] = 'l';
chararray[3] = 'l';
chararray[4] = 'o';
System.out.println(chararray);
