How to split a string in Java

public class SplitExample2 { 
    public static void main(String args[]) 
    { 
        String str = "My name is Chaitanya";
        //regular expression is a whitespace here 
        String[] arr = str.split(" "); 
  
        for (String s : arr) 
            System.out.println(s); 
    } 
}

String[] parts = string.split(Pattern.quote(".")); // Split on period.

 class Test {
         public static void main( String[] args) {
             String[] result = "Stack Me 123 Heppa1 oeu".split("\\a");                                                                                   

             // output should be
             // S
             // t
             // a
             // c
             // k
             // M
             // e
             // H
             // e
             // ...
             for ( int x=0; x<result.length; x++) {
                 System.out.println(result[x] + "\n");
             }
         }
     }
