arrays - Remove values of an entire row java -

i have string array has 10 rows , 4 columns holds contact information. if user wants remove contact, maintain 10 rows , 4 columns - without using lists in fashion - how done? instance:

contacts[0][0] = fname; //charlie         contacts[0][1] = lname; //brown         contacts[0][2] = pnum; //(309)555-1212         contacts[0][3] = age1; //10         contacts[1][0] = fname1; //sally         contacts[1][1] = lname; //brown         contacts[1][2] = pnum; //(309)555-1212         contacts[1][3] = age3; //8 

now user wants remove charlie brown contacts, , move other rows fill in empty space, maintaining total of 10 rows , 4 columns.

the lastest attempt is:

private void removecontact(string[][] contacts)     {            scanner input = new scanner(system.in);         string lname;         string fname;         int findex;         int lindex;         system.out.println("what first name of contact remove?");         fname = input.nextline();         system.out.println("what last name of contact remove?");         lname = input.nextline();         boolean found = false;          (int = 0; < contacts.length; i++)          {             (int j = 0; j < 4; j++)             {                                if (contacts[i][0].equalsignorecase(fname) && contacts[i][1].equalsignorecase(lname))                 {                     found = true;                     break;                 }                 else                  {                     system.out.println("that contact not found.");                     return;                 }             }             if (found)              {                 contacts[i][0] = null;                 contacts[i][1] = null;                 contacts[i][2] = null;                 contacts[i][3] = null;                 return;             }                                            }     } 

this works great if want remove charlie brown, other row...it doesn't work

you have code for-loop shift elements if want use arrays.

to achieve this:

int ind; //the index you'd remove. for(int = ind + 1; < array.length; i++){     array[i - 1] = array[i]; } //set last value nulls or something. 

consider arraylist: https://docs.oracle.com/javase/7/docs/api/java/util/arraylist.html it'll shifting you.

also, might want make people objects , make array (or arraylist) 1 of people. way won't have keep track of attributes of contacts arbitrary numbers , can have more readable , re-usable code.
