Reading Strings from a file and putting them into an array with Groovy

Question

Pardon the newbie question but I am learning how to do basic stuff with Groovy. I need to know how to either read words from a file (let's call the file list.txt) or from the keyboard and store them into an array of strings (let's say an array of size 10) and then print them out. How would I go about doing this? The examples I find on this matter are unclear to me.

Solution 1

how about:

def words = []
new File( 'words.txt' ).eachLine { line ->
    words << line
}

// print them out
words.each {
    println it
}

Solution 2

Actually this is quite easy:

String[] words = new File('words.txt')

Alternatively, you can use :

def words = new File('words.txt') as String[]

@Inquirer21 it is a keyword when using a Closure. it is the current Object of the iteration. You can rename it as has been done in the first part where it is renamed to line

@Inquirer21 it is a reference to implicit objects in the closure; in this case, you can reference elements in words using it

Oh alright thanks. Does anyone know hot to read input from the keyboard into an array of strings?

I guess I will need to ask that in a different question.

Note that this assumes, from your initial question, that you have one word per line.
