but need know how code this.

some line of code: string holder2; arraylist persons = new arraylist<>();

    for(int = 0; < listofcustomers.length; i++)     {         holder2 = listofcustomers[i];         persons.setdata(holder2);        }       collections.sort(persons);  } 

here's how go :

1. store these lines in srting array or arraylist
2. for each line, find position of $ string's chatat() method , extract number out of string
3. store these strings in map, key designating line number, , value number extracted in #2
4. sort map according values given here
5. now have map sorted according values , keys represent sorting order of lines!
