i have array of contact objects has max of 50 contacts, have less, array initialized size of 50. need method remove contact , shift after up. have seems work @ times, not every time.

   public contact remove(string lstnm)   {        int contactindex = findcontactindex(lstnm); // gets index of contact needs removed   contact contacttoberemoved;    if(contactindex == -1) // if contact not in array   {       contacttoberemoved = null;   }   else   {       contacttoberemoved = contact_list[contactindex]; // assigns contact going removed       for(int = contactindex; < numcontacts; i++) // contact removed last contact in list       {           contact_list[i] = contact_list[i + 1]; // shift of contacts after 1 removed down       }       numcontacts -= 1; // 1 contact removed total number of contacts   }   return contacttoberemoved; 

}

arrays fixed size cannot resize them. arraylist on other hand auto resize each time add element.

so if have array of 5 can put 5 items in it, no more no less. 1 thing can set objects in array null or 0.

edit: regards comment, sort array. easy bubble sort algorithm in java.
