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.
When programming in Groovy, we will usually work with lists rather than arrays. In case there is need to work specifically with arrays, below are examples on how to perform different things to a Groovy Array.
The Groovy times is one of the simplest and most useful method for looping in Groovy. This is very helpful if you know exactly how many times you want to loop and the syntax is as simple as it get. Here are some examples.
The Groovy print method is similar to Java's System.out.print method. This method prints a value to the current out variable which can either be the PrintWriter or the standard out. When coding a script, this usually used to display something on the screen. Here are some Examples.
Almost all programs needs some sort of loop construct to execute a block of code several number of times. The "For Loop" is the most common and efficient way to write a loop when you know how many times a task is to be repeated. This will show examples on how to do "For Loop in Groovy". Note that most are also valid Java for loop as Groovy is a superset of Java.
