Return characters in a string from field's data

Question

I have to return specific characters from a field's data. The scenario is I have a Text field which has some data (a1h5D0000055ZLfETC-547561-12) and I need to find and return last 2 characters from the data. How to achieve the same.

Answer 1

You can use right() method.

String inputStr = 'a1h5D0000055ZLfETC-547561-12';
String resultStr = inputStr.right(2);

System.debug('inputStr  '+inputStr);
System.debug('resultStr  '+resultStr);

Output:

11:36:05:002 USER_DEBUG [3]|DEBUG|inputStr  a1h5D0000055ZLfETC-547561-12
11:36:05:002 USER_DEBUG [4]|DEBUG|resultStr  12

There are more String Methods.

Answer 2

Use substring method of String Class.

String str = 'a1h5D0000055ZLfETC-547561-12';
String resultantStr = str.substring(str.length()-2);

It will return 12 i.e. last 2 characters from str.
