Converting one type of data to another type it is also known as Type Casting.     Type Casting are of two types:           1) Implicit conversion                 int num = 2147483647;                 long bigNum = num;         2) Explicit conversion        double x = 1234.7;                int a;                // Cast double to int.                a = (int)x;
