java replaceAll(regex, replacement) regex command

问题

I would like to know if anyone knows the regex command to remove the following

 name = 

from the following

 name = wlr

leaving only

 wlr

these details are taken from a txt file but the name = part can appear multiple times

So I was thinking something like this would work but it doesn't work properly

 String file_name = newLine3.replaceAll("name = ", "");

回答1:

String file_name = newLine3.replaceAll("name\\s+=\\s+", ""); 

回答2:

String newLine3 = "name = wlr";
String fileName = newLine3.replaceAll("name = ", ""); //fileName = "wlr"

回答3:

How about:

String input = "name = wlr";
String file_name = newLine3.substring(input.indexof("=") + 1).trim();

Regex seems like overkill for this issue.
