RE2/J is a high-performance regular expression engine implemented in pure Java as a port of Google’s C++ RE2 library. Unlike traditional regex engines such as Java’s java.util.regex, PCRE, or Perl’s implementation—which rely on backtracking and can suffer from catastrophic exponential runtimes—RE2/J guarantees linear-time matching relative to input size. It achieves this efficiency by simulating all possible matches in a single pass using a nondeterministic finite automaton (NFA), ensuring predictable and safe performance even with complex patterns. ...

useful library for repetitive java stuff

JFlex is a lexical analyzer generator for Java, designed to create fast and efficient scanners. It takes regular expression specifications and produces Java code for tokenizing input text. ​

A java library for easily scheduling commands using cron expressions. Uses the cron expression parser from Quartz and the HashWheelTimer from netty. Handles DST conflicts, command exceptions, overlapping execution.

Regular Expression Builder for Java (reb4j) is a simple set of classes that encapsulate the regular expressions used by java.util.regex.Pattern and provide facilities for composing larger expressions from sub-expressions.

Math expression parser and evaluator written in Scala. Usable from Java (Sun JRE 1.6) Provides float, integral, boolean and vector data types, some string processing support. Variables may be defined internally or im- and exported through a binding.

Fastest string utility is java library (JAR ) for string operation . This library is very easy to use, very fast and very efficient in string operations such as split, toUpperCase, toLowerCase, replace, delete, regular expression and others.

Manages Java application/tool options. Options are mapped to Java Bean properties using annotations. Options can be loaded from command line arg String[] array, an XML file, or a java properties file. Help texts can be generated.
