please chk my code. it works well but is its logic correct?
Statement: Suppose we have a class named as Train it has two constructors, two methods, and a single attribute each of which described as follows:·
One attribute:maxSpeed – an int value representing the maximum speed of the Train object.
Note: Train speed of modern Trains may be something like 250 km per hour, so a value you could use for testing purposes is 250.· Two constructors:
A default constructor: A constructor that initializes the attribute ms where ms is the maxSpeed.
An overloaded constructor: A constructor that takes ms as an argument, where ms is the maxSpeed.·
Two methods:
() – return the maxSpeed value associated with the Train object.
setMaxSpeed(ms) – change the maxSpeed value associated with the Train object, where ms is the new value. ·
Display the value through default constructor and overloaded constructor.·
Display setter value through main function.
