i have arraylist containing many records like

"2013-7-13 \n 12 hour(s) 23 minute(s)"  "2013-7-14 \n 4 hour(s) 19 minute(s).

how can covert 2 dimentional array, string[][], making looks 

{"2013-7-13", "12h23m"}, {"2013-7-14", "4h19m"}.

i need 2 dimentional array can draw barchart in xy , display in android device. x represents date, while y represent time.

you can use string.split split each string parts.

// untested, not compilation errors string[][] twodimarray = new string[oldarr.length][]; (int = 0, n = oldarr.length; < n; i++) {     string splitme = oldarr[i];     twodimarray[i] = splitme.split("\n"); }
