Ans. Assigning a value of one type to a variable of another type is known as Type Casting. Example : int x = 10; byte y = (byte)x; In Java, type casting is classified into two types, Widening Casting(Implicit) widening-type-conversion and Narrowing Casting (Explicitly done) narrowing-type-conversion. Widening or Automatic type converion - Automatic Type casting take place when,the two types are compatible and the target type is larger than the source type Example : public class Test { public static void main(String[] args) { int i = 100; long l = i; //no explicit type casting required float f = l;//no explicit type casting required System.out.println("Int value " i); System.out.println("Long value " l); System.out.println("Float value " f); } } Narrowing or Explicit type conversion - When you are assigning a larger type value to a variable of smaller type, then you need to perform explicit type casting. Example : public class Test{ public static void main(String[] args) { double d = 100.04; long l = (long)d; //explicit type casting required int i = (int)l;//explicit type casting required System.out.println("Double value " d); System.out.println("Long value " l); System.out.println("Int value " i); } } | ||||
