Populating a 2D array in Javascript with random numbers

问题 I'm trying to populate a 2D array in javascript with random numbers. Although each column in the array is random, each row is identical which is not what I want (see image below). I want both rows and columns to be random. http://eeldesigns.com/image.jpg cols = 5; rows = 10; front = new Array(cols).fill(new Array(rows)); // Loop through Initial array to randomly place cells for(var x = 0; x < cols; x++){ for(var y = 0; y < rows; y++){ front[x][y] = Math.floor(Math.random()*5); } } console

Populating a hashmap with predefined values (java)

问题 I've run into a problem I haven't had to deal with before. I'm writing a patch for a database in java that's basically converting data stored in certain rows. In order to do this I have a conversion table that tells me what values become what. Example, if I read in either "RC", "AC", "GH" -> Update the value to "T1". (These are just random examples, it's basically converting one string to another.) I need a good way of storing these conversions. I was thinking a hashmap: KEY,VALUE: (RC,T1)
