Can you pull apart a string?

Question

I'm storing a string in a database with a value such as "020734". I would like to be able to pull the string apart.

I have:

String values = "020734";

I need:

String values = "020734";
String value1 = "02";
String value2 = "07";
String value3 = "34";

Could you guys possibly point me in a general direction?

Answer 1

Erm, how about value1 = values.substring(0, 2); value2 = values.substring(2,4)...etc? That will get you two characters at a time from the string.

Answer 2

Well, if you always know the widths of the values you want then you could do the following:

String remainder = startString;
while (remainder.length() >= 2) {
    String newPart = remainder.substring(0, 2);
    // you can do something with each part
    remainder = remainder.substring(2, remainder.length());
}

This will break any string up into 2 character chunks.

You can view the substring() documentation here:

Answer 3

checkout String.substring.

String values = "020734";
String value1 = values.substring(0, 2);
String value2 = values.substring(2, 4);
String value3 = values.substring(4, 6);
