java - how to split the string and store it in array -


i have tried following example gives following out put output[]. have pass string "1.0" function calculatepayout() , want store 1 in s[0] , 0 in s[1]

import java.util.arrays;       public class aps {          public void calculatepayout(string amount)         {             string[] s = amount.split(".");             system.out.println("output"+arrays.tostring(s));         }      public static void main(string args[])     {         new aps().calculatepayout("1.0");     }     } 

method split() accepts regular expression. character . in regular expressions means "everything". split string . have escape it, i.e. split("\\."). second slash needed because first 1 escapes dot regular expression, second escapes slash java compiler.
