you can regex

string str = "success entries , failed entries: {failed_entries={}, success_entries={123=1509180522720153332, 124=1509181140480153332}}"; matcher matcher = pattern.compile("(?<=(success_entries=\\{)).+?(?=\\})").matcher(str); matcher.find(); str = matcher.group(); system.out.println(str); matcher = pattern.compile("(?<=\\d{3}=)\\d+").matcher(str); while(matcher.find()){     system.out.println(matcher.group()); } 

but remember regex lookbehind/lookahead not in performance
