I am unable to solve this.

You can read about StringBuilder too

Hey Daniel, I doubt you're still on this problem...at least i hope you're not but I would recommend using StringBuffer and deleting the first character each time. This way you're not creating new string objects each time you loop.

Use substring method of String class and iterate over the String indexes

You can read about String methods in official documentation of Oracle.

I am not an expert, but I would suggest you either: 1-convert the string to char[] and loop through the characters to make a new String,with each String removing one Character. 2-convert into an Arraylist<Character>, loop through removing one arraylist at a time, make a new string with each new shrinking Arraylist<Character>. hope that helps

This task requires you to remove one space from the beginning of the text line each loop cycle. Use google to help.
