This example illustrates that what is type casting? Type Casting refers to changing an entity of one datatype into another. This is important for the type conversion in developing any application. If you will store a int value into a byte variable directly, this will be illegal operation. For storing your calculated int value in a byte variable you will have to change the type of resultant data which has to be stored. This type of operation has illustrated below :
In this example we will see that how to convert the data type by using type casting. In the given line of
c = (char)(t?1:0); illustrates that if t which is
type variable is true then value of c which is the char
type variable will be 1 but 1 is a numeric value. So, 1 is changed into
character according to the Unicode value. But in this line c = (char)(t?'1':'0');
1 is already given as a character which will be stored as it is in the
type variable c.
