A regular expression is a special sequence of characters that helps in matching or finding other strings or sets of strings, using a specialized syntax held in a pattern. Java has support for regular expression usage through the
java.util.regex package. This topic is to introduce and help developers understand more with examples on how Regular Expressions must be used in Java.
Python makes regular expressions available through the
Regular expressions are combinations of characters that are interpreted as rules for matching substrings. For instance, the expression
'amount\D+\d+' will match any string composed by the word
amount plus an integral number, separated by one or more non-digits, such as:
amount is 3,
amount is equal to: 33, etc.
Regular Expressions (sometimes called regexs or regexps) are a textual syntax which represents the patterns which can be matched in the strings operated upon.
Regular Expressions, introduced in c++11, may optionally support a return array of matched strings or another textual syntax defining how to replace matched patterns in strings operated upon.
