Web Reference: Note: This rule makes Java safer, because the compiler will stop you if you try to mix up types by mistake. If you really need to change between types, you must use type casting or conversion methods (for example, turning an int into a double). An object of type Double contains a single field whose type is double. In addition, this class provides several methods for converting a double to a String and a String to a double, as well as other constants and methods useful when dealing with a double. Learn how to use the double data type in Java, a 64-bit floating point for high-precision calculations. See syntax, examples, and tips for scientific and financial applications.
