How do I create and access the global variables in Groovy?

Question

I need to store a value in a variable in one method and then I need to use that value from that variable in another method or closure. How can I share this value?

Answer 1

def sum = 0

// This method stores a value in a global variable.
def add =
{ 
    input1 , input2 ->
    sum = input1 + input2;
}

// This method uses stored value.
def multiplySum =   
{
    input1 ->
        return sum*input1;
}

add(1,2);
multiplySum(10);
