Narrowing Casting (manually)- converting a larger type to a smaller size type double->float->long->int->char->short->byte doublemyDouble = 9.78d;intmyInt =(int)myDouble;//Manual casting: double to intSystem.out.println(myDouble);//Outputs 9.78System.out.println(myInt);//Outputs 9...
Here's a real-life example of type casting where we create a program to calculate the percentage of a user's score in relation to the maximum score in a game. We use type casting to make sure that the result is afloating-pointvalue, rather than an integer: ...
The above program generates the following output. Implicit Casting of a Class Type in Java When we are assigning a smaller type to a larger type, there is no need for casting required. The same applies to the class type, as well. The complete program is listed below. class Parent { publ...
class Demo2 { public static void main(String args[]) { byte b; int i = 355; double d = 423.150; b = (byte) i; System.out.println("Conversion of int to byte: i = " + i + " b = " + b); System.out.println("***"); b = (byte) d; System.out.println("Conversion of...
During compile-time, the compiler checks the validity of the cast based on the class hierarchy and ensures that the casting is done only between classes that have an inheritance relationship. If the casting is not allowed, the compiler raises a compile-time error. ...
The IS-A Relation is based on the type of Inheritance implemented, and next, the decision is based on whether it is an interface inheritance or class inheritance. Let us look into an example for a better understanding. Example: //IS-A Relation package simplilearnJava; import java.util.*; ...

Hence this problem can be colved by a simple downcast by casting the Car object reference to the Ford Class Object reference as done in the program. Also an attempt to cast an object reference to its Sibling Object reference produces a ClassCastException at runtime, although compilation ...
