I know that following similar thing is possible:-
- to delete a character from an array(by replacing with bblank space)
-
Deleting an index!?! Arrays are stored in contiguous memory locations, how can you delete an index from somewhere in between that range?CinCout– CinCout2015-02-23 04:01:19 +00:00Commented Feb 23, 2015 at 4:01

In java array is of fixed lengths, you cant delete index of aa arrayBirlla– Birlla2015-02-23 04:02:31 +00:00Commented Feb 23, 2015 at 4:02

you should look into ArrayList instead. you could assign null to the index like array[index]=null i suppose. your questions ambiguous.j2emanue– j2emanue2015-02-23 04:02:48 +00:00Commented Feb 23, 2015 at 4:02

1Not sure if it accomplishes what you're asking, but you could create a new array, the size being 1 smaller, and add the values you wish to the new array.Dando18– Dando182015-02-23 04:13:07 +00:00Commented Feb 23, 2015 at 4:13

I don't think he really wants to delete the index, just replace it by blank space.m0skit0– m0skit02015-02-23 04:13:32 +00:00Commented Feb 23, 2015 at 4:13

You cannot delete an index from an array. This is because arrays have a fixed length that cannot be changed. If you want a list which you can delete elements, check out the ArrayList class. Here is the documentation: http://docs.oracle.com/javase/7/docs/api/java/util/ArrayList.html

Not just Java, you just cannot delete an array's index in any language whatsoever!
Just assign the blank space to the position of the character you want to replace - it's not a real deletion, an array in Java is of fixed length (it can't be resized):
array[index] = ' ';
