java - Deleting an item from an array using arraycopy -


i having problems deleting item array using arraycopy. have 2 methods find (which locates index of item deleted) , delete (which deletion). doesn't delete anything. thank in advance.

 public void find(comparable value2){     scanner sc = new scanner(system.in);     comparable value = value2;      if (empty() == true){         system.out.println("the array empty");      }     else{     int bsvalue = arrays.binarysearch(sa,value);     system.out.println("the index is: " + bsvalue);     delete(bsvalue);     }     }   public void delete(int bs){      int location = bs;         comparable[] temparray = new comparable[sa.length -1];      system.arraycopy(sa, 0, temparray, 0, location);      if (sa.length != location){          system.arraycopy(sa, location +1 , temparray, location, sa.length - location - 1);      }       }

you allocate temparray, copy data it, , abandon reference. result, original array (sa) stays was.

presumably meant make sa point new array:

sa = temparray;

Why does Ruby on Rails generate add a blank line to the end of a file? -
