String to Int in Groovy

In Groovy, you can convert a string to an integer using the toInteger() method. Here is an example:

def myString = "42"
def myInt = myString.toInteger()
println(myInt)

This code defines a string variable called myString with a value of "42". It then converts this string to an integer using the toInteger() method and stores the result in a new variable called myInt. Finally, the code prints the value of myInt to the console, which should output the integer 42.

Note that if the string contains non-numeric characters, the toInteger() method will throw a NumberFormatException. For example:

def myString = "42abc"
try {
    def myInt = myString.toInteger()
} catch (NumberFormatException e) {
    println("Error: ${e.message}")
}

In this code, the string variable myString contains non-numeric characters ("abc"). When we try to convert this string to an integer, the toInteger() method throws a NumberFormatException. We catch this exception and print an error message to the console.
