Comment on Tutorial : Type Casting in Java By Saravanan
Design program with given algorithm---

step1:Declare a variable x of type integer and assign it to the value 10
Step 2: Declare a variable y of type double and assign it the value of x.
Step 3: Print the value of y it will show no error itâs called implicit casting.
Step 4: Now, Set the value of y to 13.5
Step 5: Assign value of y to the x. (It raises compilation error because implicit casting doesnât work as explained.)
Step 6: Use explicit casting (narrowing conversion) to assign y to x.
Step 7: print value of x (it gives you round off value y).
Step 8: Define a class named vehicle as a parent class, define a subclass of vehicle as car.
Step 9: create an object x of class vehicle.
Step 10: create an object y of class car.
Step 11: assign y to x (Its upcasting so no compilation error and no explicit casting is required)
Step 12: assign x to y (Its downcasting so it will give u compilation error. So use explicit casting)
