Example : int x = 10; byte y = (byte)x; In Java, type casting is classified into two types, Widening Casting(Implicit) Narrowing Casting(Explicitly done) Widening or Automatic type converion An object can be converted from one data type to another using typecasting, also known as type conversion. It is the most frequently used casting wherein it is communicated to the compiler that the value of the base object isnt its own but of the SuperType object. For example: s. charAt(0) would return the first character of the string represented by instance s. Double: It is a double-precision 64-bit (8 bytes) IEEE754 floating point.

Type casting are of two types they are SQL NSFileManager or NSPathUtilities in Objective-C, Passing data between view controllers in Objective-C. Typecasting from smaller type to larger type size: byte -> short -> char -> int -> long -> float -> double. Though the purpose of this method is to format a string, it can also be used for conversion. The default value of a byte data type is 0. After that call toString() method on the StringBuffer object to convert StringBuffer to string. To learn more, see our tips on writing great answers. Object aSentenceObject = (Object)aSentenceString; Here we are taking a variable with a more specific type ( String) and casting it to a variable type that's more generic ( Object ). Lets understand widening casting with objects using an example: In the above code, the Animal class is called the parent class, and the Dog class is called the child class because the Dog class extends the Animal class, and the Dog class has acquired all the properties of the Animal class: The process of conversion of higher data type to lower data type is known as narrowing typecasting. Convert String to int Below example uses Integer.parseInt (String) to convert a String "1" to a primitive type int. Every object can be casted to an java.lang.Object, not a String.
