Groovy - Select position for related arrays and verify contents
Hello, I have been looking for almost a week now around how to best approach this but cannot find anything. I have two arrays which are related that are storing values from a loop through a J...

I'd go with a matrix-approach. Define three lists in a list, one for index and two for your values. The just run find on the index-column and use the value to test the other two columns for what you are looking for.
def matrix = [[],[],[]]; //Populate the matrix for this example 3.times { i -> matrix[0][i] = i matrix[1][i] = "POST $i" matrix[2][i] = "TYPE $i" } //matrix //[[1, 2, 3], //[POST 0, POST 1, POST 2], //[TYPE 0, TYPE 1, TYPE 2]] //Search the indices and check the other two columns //for their values using the current index int indexOfPost2Type2 = matrix[0].find { i -> matrix[1][i] == 'POST 2' && matrix[2][i] == 'TYPE 2' } //indexOfPost2Type2 == 2
try it out and see how that works. :)
