/*Output:

Runtime error ......

10 9 6 5

5 6

When printing on different lines there is blank spaces in between.

When printing on same line output:10109651256.

length of splitted array is 14.

What are these spaces blanks or NULL?

Why aren't they printing on the same line?//

Additionally to the duplicate mark, write your regex as `"[(,{})]+"`, otherwise you will have plenty of empty `Strings` when it splits at `,{` or `}),(` for example. – SomeJavaGuy Mar 12 '16 at 11:01
First of all thanks for your reply – sfbjabf Mar 12 '16 at 11:08
Sir, there is still a empty String at 1st position (Oth index) of strArray. – sfbjabf Mar 12 '16 at 11:09
remove the trailing split delimiter with `s = s.replaceFirst("[(,{})]+", "");`, before you are splitting the `String` – SomeJavaGuy Mar 12 '16 at 11:10
