Regular Expression to find “lastname, firstname middlename” format

Question

I am trying to find the format \"abc, def g\" which is a name format \"lastname, firstname middlename\". I think the best suited method is regex but I do not have any idea i

Answer 1

I would try and avoid a complicated regex, I would use String.substring() and indexOf(). That is, something like

String name = "Last, First Middle";
int comma = name.indexOf(',');
int lastSpace = name.lastIndexOf(' ');
String lastName = name.substring(0, comma);
String firstName = name.substring(comma + 2, lastSpace);
String middleName = name.substring(lastSpace + 1);
System.out.printf("first='%s' middle='%s' last='%s'%n", firstName,
            middleName, lastName);

Output is

first='First' middle='Middle' last='Last'
