How to Parse A String Of Version Numbers In Groovy?

a minute read

To parse a string of version numbers in Groovy, you can use the split() method to split the string into an array of strings, using a regex pattern that matches the version number format. Once you have the array of strings, you can then convert each string to an integer or a floating-point number to compare the version numbers. You can also use the Version.parse() method provided by Groovy's org.codehaus.groovy.runtime package to parse and compare version numbers directly.


How to split a string in Groovy?

In Groovy, you can split a string using the split() method. Here's an example of how to split a string by a certain delimiter:

1
2
3
4
5

def myString = "Hello,World,How,Are,You"
def parts = myString.split(",")

// Output the parts
parts.each { println it }


In this example, the split() method is called on the myString variable with a comma , as the delimiter. The resulting array of parts is then printed out using the each method.


What is the use of the matcher method in Groovy?

In Groovy, the matcher method is used to create a Matcher object for a given input string. This object can be used to perform various operations, such as finding matches, extracting groups, replacing matches, etc. It is particularly useful when working with regular expressions, as it provides a convenient way to work with pattern matching in Groovy.
