Problem scenario
You are running a Groovy program.
Here is your code:
def input = System.console().readLine 'Please provide some input: '
def x = input
def boardArray = new String[2]
boardArray[0] = ""
boardArray[1] = ""
boardArray[1] = "$x"
println boardArray[1]When you run it (i.e., with groovy foobar.groovy), you get this error:
Caught: java.lang.ArrayStoreException: org.codehaus.groovy.runtime.GStringImpl
java.lang.ArrayStoreException: org.codehaus.groovy.runtime.GStringImpl
What should you do?
Solution
To assign an element of an array, should have quotes around the variable and the $ symbol and the syntax " as String" should follow the closing quote mark.
def input = System.console().readLine 'Please provide some input: '
def x = input
def boardArray = new String[2]
boardArray[0] = ""
boardArray[1] = ""
boardArray[1] = "$x" as String //This is the correct version
println boardArray[1]You may also want to view this external web pages:
