Now we are done with discussing both the classes. Here we will be discussing a few java programs that demonstrate the workings of compile(), find(), start(), end(), and split() in order to get a better understanding of the Matcher class. Let us do discuss a few sample programs as we did for Pattern class. Other methods (demonstrated below) are mainly used to find multiple occurrences of patterns in the text. Note: T Pattern.matches() checks if the whole text matches with a pattern or not. It is used to test whether the regular expression matches the pattern. It is used to find the matched subsequence. It is used to find the total number of the matched subsequence. It returns the index of the character next to the last matching character. It is used for getting the end index of a match that is being found using find() method. It is used for getting the start index of a match that is being found using find() method. It is used for searching occurrences of the regular expressions in the text starting from the given index. It is mainly used for searching multiple occurrences of the regular expressions in the text. This can be implemented by invoking a matcher() on any pattern object. This object is used to perform match operations for an input string in java, thus interpreting the previously explained patterns. It is used to return the string representation of this pattern. Otherwise, all characters between the patterns will be copied. When this option is checked, the generated regular expression will only contain the patterns that you selected in step 2. The limit parameter controls the number of times the pattern is applied. Hover the generated regular expression to see more information. It is used to split the given input sequence around matches of this pattern. It is used to return a literal pattern String for the specified String. It is used to return the regular expression from which this pattern was compiled. It is used to compile the given regular expression and attempts to match the given input against it. Matches(String regex, CharSequence input) It is used to create a matcher that will match the given input against this pattern. It is used to return this pattern’s match flags. It is used to compile the given regular expression into a pattern with the given flags. It is used to compile the given regular expression into a pattern. This can be created by invoking the compile() method which accepts a regular expression as the first argument, thus returns a pattern after execution. This class is a compilation of regular expressions that can be used to define various types of patterns, providing no public constructors.
