trim() function in String class is used to remove both leading and trailing
(white)spaces of a String.

for example:-

String str = " Hello World ");

will print only "Hello World" in ur console.
note: it will not remove blank spaces in-between the String

If question is about, what trim( ) does, trim( ) returns a copy of the
string, with leading and trailing whitespace omitted.

Please note trim( ) removes leading and trailing spaces only, not spaces
which are in mid of some letters.

For eg:

str = " s t r ";

str.trim() retruns "s t r" means  it does not removes spaces in between
any letters.
