Question

Using Java, define a train class and write code to demonstrate its functionality

The train should run between Boston and New York, stopping at different, different station along the way.

Provide output to indicate the train’s current status.

import java.util.LinkedList;

/*******************************output*****************/

Train at: Boston
Train's last station: New York
Now train at: Staion B
Now train at: Staion D
You have reached at: New York
Now train at: New York

Please let me know if you have any doubt or modify the answer, Thanks :)
