Help with parse string into object

[jay lai]

I have an POJO call myObject.java have the 4 attributes(id, pos1, pos2, pos3) with getter/setter.

I have a method need to return ArrayList<MyObject> taking the String and parse out into the object. The string is concatinate of the number of records, and now they want to split into the field like in the table with columns

Ex:
String: 000111122233311122223334442223333444555
expect return id     pos1     pos2   pos3
              000    1111     222    333
              111    2222     333    444
              222    3333     444    555
 
public ArrayList<MyObject> getData(String concatinateString, int numOfRecords)
{
 concatinateString = "000111122233311122223334442223333444555";
 numOfRecords  = 3;
 //so here what do i do to get it parse into the object like sample above
}
 

Please help or hint thanks, Greately appreciated

What is the logic for splitting the String? For example, will it always be 3 chars, followed by 4 chars, followed by 3 chars, followed by 3 chars?
