Question

How could one populate a 2d array from a text file using split?

String proxies[][] = {{"127.0.0.1","80"}, {"127.0.0.1","443"}, {"127.0.0.1","3306"}};

In my text file I have data with a ip:port on each line:

127.0.0.1:80
127.0.0.1.443
127.0.0.1.3306

I could populate a 1d array using split like this:

proxies = everyLine.split("\\n");

How would I insert the ip:port data into a 2d array?

Answer 1

    String[] lines = everyLine.split("\\n");
    String[][] proxies = new String[lines.length][];
    int i=0;
    for ( String line : lines )
    {
        proxies[i++] = line.split(":");
    }
