Difference between EReplace and CHANGE in talend String Handling

[Anonymous]

Hi All,
Can anybody explain what is exact difference between EReplace and CHANGE routines under String Handling ?
I'm little confuse while using it.
StringHandling.CHANGE("Hello ABC","Hello","bye") => bye ABC
StringHandling.EREPLACE("Hello ABC","Hello","bye") => bye ABC
Any help....?
Regards,
Vishal

Hi,
There is no difference between EReplace and CHANGE in talend String Handling. We think it is a duplicated issue. Our colleagues from test team have reported a bug for it https://jira.talendforge.org/browse/TDI-24223.
Best regards
