Getting a substring from another String is one of the basic building blocks of String manipulation. Most programming languages supports it out of the box. In Groovy, there are some cool ways of how to perform this operation. Below are some examples on different ways of getting substrings in Groovy.
Maps are very useful in programming. It can be used to cache results of expensive operations to help improve performance. One of the basic operation in maps is how to add entries to it. Below are some examples on how to Add or put values to a map in Groovy.
Groovy is popular for writing short and concise codes. Programs that contains many lines of code using Java can be shortened in Groovy. This greatly helps in developer productivity. A feature that is commonly used in Groovy is in searching for items in a collection. The Groovy FindAll method searches for a subset of a collection that matches a given criteria. Here are some examples on how to use Groovy FindAll:
Groovy is one of the coolest language available because it makes coding so much easier. Long Java codes can be written in Groovy in fewer lines that are much more readable. One of the most used feature in Groovy is in searching. The Groovy Find method can be used to search for a single object in a collection, given a condition on what needs to be searched for. Below are some examples on how to use Groovy Find for searching.
When we declare a variable or function in Groovy, we can use the def keyword to define the type. The Groovy Def can be used if we don't want to restrict the type of an object. Hence, we can change what can be assigned to a variable any time during runtime. When we use Groovy def to declare something, it is similar to declaring it as an Object class. Because the class Object is the root class of all classes, you can assign anything to a variable of type Object. Here are some examples on how to use def in Groovy.
File processing is one of the most common task in programming. Fortunately, Groovy makes file manipulation easier. Things that are long and complicated in Java are now very much concise in Groovy. Here are some Groovy File programming examples.
