如何通过BufferedReader加载String？

Question

I need to load in a given String which will be type in as an input String：

             20 6
             ....................
             ..XXXXX..XXX.XXX..X.
             ..X.X.X..X.XXX.X..X.
             ..XXXXX..XX.X..X....
             ..XX......XXXXXX..X.
             ....................

something like that. It contains 2 integers and a String with "." and "X" Now I just want to ask 2 questions: 1)I need to load the 2 integers first,but how can get the first two integers by BufferedReader?(the 2 int is divide by space between each other and the rest)

2)Then after loading the two integers,how can I load the following rest string char by char?(Like everytime I need to just load one char,then I go to some function,then come back and load the next char;and between there is no blank space)

Here is part of my code:

       BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
       String str=br.readLine();
       number1 = Integer.parseInt();
       number2 = Integer.parseInt();

And now I don't know how to continue...Anyone can help me to load it?

Answer 1

For 1) you just need to do a split

 BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
   String str=br.readLine();
   String ints[] = str.split(" ");
   number1 = Integer.parseInt( ints[0] );
   number2 = Integer.parseInt( ints[1] );

Then for 2) once you have a String you can have it length and so get them char by char ;)

String lol = "......XXX..XX...";
for( int i = 0; i < lol.length(); i++ )
    System.out.println(lol.charAt(i));

With this you will get all your string char by char

It is much better if you use Scanner then you can read int and the String easier. I suppose you input two integers as col and row. Example like this:

Scanner scan = new Scanner(System.in);
int col = scan.nextInt();
int row = scan.nextInt(); //input two int first
scan.nextLine();
for(int i = 0; i < row; i++) { 
    String s = scan.nextLine();
    for(int j = 0; j < col; j++) {
        char c = s.charAt(j);
        //your code here
    }
}
