getting string from string start wtih "abc" and end with "def"

I am using StringUtils (import org.apache.commons.lang3.StringUtils;) library to split string like:

String str = "ZXCVFMS2ZZ1012ZZ1012ZZ1000ZZ0923ZZ0990ZZ0990ZZ0990ZZ1020DEFZXCVFMS3ZZ1012ZZ1012ZZ1000ZZ0923ZZ0990ZZ0990ZZ0990ZZ1020DEFZXCVFMERRORDEF";

I need to take out string start with zxcv* and end with *def as

String tmp1 = "ZXCVFMS2ZZ1012ZZ1012ZZ1000ZZ0923ZZ0990ZZ0990ZZ0990ZZ1020DEF";
String tmp2 = "ZXCVFMS3ZZ1012ZZ1012ZZ1000ZZ0923ZZ0990ZZ0990ZZ0990ZZ1020DEF";

any help?
