How to sort HashMap based off the order they were parsed in using Java?

Question

I have a HashMap which is made up of parsed values from a textfile. Whenever I extract the contents from this HashMap, they come out in abc order. How do I keep the order that they were parsed, basically in a FIFO order.

Use a LinkedHashMap, which can preserve insertion order.

HashMap itself is not capable of preserving the order information. Have a look at other implementations, the standard library contains LinkedHashMap for example.
