ProblemStatement:

Supposewe have a class named as Train it has two constructors, twomethods, and a single attribute each of which described asfollows:

One attribute:

maxSpeed– an int value representing the maximum speed of the Trainobject.

Note: Train speed of modern Trains may be something like 250 km perhour, so a value you could use for testing purposes is 250.

A defaultconstructor:

A constructor thatinitializes the attribute ms where ms is the maxSpeed.

An overloaded constructor:

A constructor that takes msas an argument, where ms is the maxSpeed.

getMaxSpeed()– return the maxSpeed value associated withthe              Train object.

setMaxSpeed(ms) –change the maxSpeed value associated with the Train object, wherems is the new value.
