They are also used for manipulating text and data. This book will provide you with the know-how (and practical examples) to solve real-world problems using regex in Java.\u003c\/p\u003e\u003cp\u003eYou will begin by discovering what regular expressions are and how they work with Java. This easy-to-follow guide is a great place from which to familiarize yourself with the core concepts of regular expressions and to master its implementation with the features of Java 9. You will learn how to match, extract, and transform text by matching specific words, characters, and patterns. You will learn when and where to apply the methods for finding patterns in digits, letters, Unicode characters, and string literals. Going forward, you will learn to use zero-length assertions and lookarounds, parsing the source code, and processing the log files. Finally, you will master tips, tricks, and best practices in regex with Java.\u003c\/p\u003eStyle and approach\u003cp\u003eThis book will take readers through this learning journey using simple, easy-to-understand, step-by-step instructions and hands-on examples at every stage.\u003c\/p\u003e","brand":"Packt Publishing","offers":[{"title":"Default Title","offer_id":47152684794096,"sku":"9781787288034","price":27.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0737\/7593\/9824\/files\/9781787288034_p0.jpg?v=1763738857","url":"https:\/\/shop-qa.barnesandnoble.com\/products\/9781787288034","provider":"Barnes \u0026 Noble (DEV)","version":"1.0","type":"link"}
