java - how to group all of the characters of String into a 2d char array? -

i'd know how group of characters of string char [][]. suppose have

string m = "x b \n"+                      "s d w \n"+                      "d e f" 

how can group characters of above string 2d char? method should group characters are, i.e.:

x b s d w d e f  public void  groupchars (string lines) {    char [][]temp = new char [3][3];  } 

one way of doing way [though have used string array]

public class test1 {     public static void main(string args[])     {         string s = "x b \n"+                 "s d w \n"+                 "d e f";              string[] splitparts = s.split(" ");              string[][] newarray = new string[splitparts.length/3][3];             (int = 0, = 0; < newarray.length; a++) {                 newarray[a][0] = splitparts[i++];                 newarray[a][1] = splitparts[i++];                 newarray[a][2] = splitparts[i++];             }             system.out.println(java.util.arrays.deeptostring(newarray));       } } 

output:

[[x, a, b], [ s, d, w], [ d, e, f]]
