Java Get Map Of X-Y Coordinates From String

Is there any way to get a map of java.awt.Points from a String? Or even just a single point on that String. For example for "xyz123\nabc123" coordinate (0, 1) would be 'a'.

Solution

  • There is nothing built-in for that.

    You can try and parse that string into a 2D char array or a vector of char arrays (depending on if you know how many lines in total or not).

    Given "xyz123\nabc123" as str:

    //split it by newline, should work on windows/unix
String lines[] = str.split("\\r?\\n");  
char[][] map = new char[lines.length][];
//fill up map, each row is a new line
for(int i = 0; i < lines.length; i ++)
map[i] = lines[i].toCharArray();
//map[0][2] returns 'z'
