Hello

Can the length of primitive data types like byte[], be dynamically
reduces in java. For ex in the following code

class test
{

public static void add()
 {

   file://create a 20 byte array
   byte []mname=new byte[20];

    String s="madhur";

   file://initialize all the fields
    for(int i=0;i<20;++i)
    {
     mname[i]=3;
    }

   file://convert a string to byte[]
    mname=s.getBytes();

/* rest of the fields with 0*/

    for(int i=s.length()-1;i<20;++i)
    {
      try
      {

       mname[i]=0;
      }
      catch(Exception e)
      {
       System.out.println("Exception at:" + i);
      }
    }
   }

   public static void main(String args[])
   {
    add();
   }
}

In the above procedure, when I am filling the mname array with 0, it
produces
the *ArrayIndexOutOfBoundsException* starting from location 6.

Why does this exception occurs since I have specified the array size to be
20 and even initialized the all the fields.
