Split String Every X String does not work

Question

I have a String, in which I want to split Every x String. I want to split every 7 String and it works ! Here is the code and the String. Here is the String :

 ArrayList<String> arrayList=new ArrayList<String>();

        String str="br_mgt>eth0>63 br_mgt>ath0>63 br0>br_mgt.100>63 br_data>eth0>63 br_data>ath0>63 br0>br_data.200>63 br_data>eth0>63 br_data>ath0>63 br0>br_data.200>75";

        String[] theString=(str.split("(?<=\\.......)"));
        System.out.println("First One : " + theString[0]);
        System.out.println("Second one : " + theString[1]);

Output is :

First One : br_mgt>eth0>63 br_mgt>ath0>63 br0>br_mgt.100>63
Second one :  br_data>eth0>63 br_data>ath0>63 br0>br_data.200>63

And It is true and what I wanted. I change the String to :

str="br0>br_mgt.333>63 br_mgt>eth0>63 br_mgt>ath0>63";

And the output is :

First One : br0>br_mgt.333>63
Second one :  br_mgt>eth0>63 br_mgt>ath0>63

Why is that?

I think you are looking for the substring method.

ex.

String string1 = "CatDog";
String string2 = string1.substring(0,3); //contains 'Cat'
String string3 = string1.substring(3);   //contains 'Dog'
