Cut Java String at a number of character

Question

I would like to cut a Java String when this String length is > 50, and add "..." at the end of the string.

Example :

I have the following Java String :

String str = "abcdefghijklmnopqrtuvwxyz"; 

I would like to cut the String at length = 8 :

Result must be:

String strOut = "abcdefgh..." 

Answer 1

Use substring and concatenate:

if(str.length() > 50)     strOut = str.substring(0,7) + "..."; 

Answer 2

StringUtils.abbreviate("abcdefg", 6);

This will give you the following result: abc...

Where 6 is the needed length, and "abcdefg" is the string that needs to be abbrevieted.
