The design principles and practice of PrimitiveTypes in GUAVA

The design principle and practice of PrimitiveTypes in Guava Guava is a tool library provided by Google for Java developers to simplify the tedious tasks in the daily encoding process and provide efficient data structure and algorithm.Among them, Guava's PrimitiveTypes module is a very useful and powerful tool, which provides some methods and practical programs for basic data types. Design principle: The design principle of the design of Guava's PrimitiveTypes module mainly includes the following aspects: 1. Basic data type: The PrimitiveTypes module processs the basic data type by providing a packaging class with basic data types.These packaging categories provide rich methods and practical programs, making it more convenient and flexible when processing basic data types. 2. Support basic type conversion: The PrimitiveTypes module provides the function of converting the basic data type.Through these conversion methods, you can easily convey between different basic data types to avoid the complexity of manually writing the transformation logic. 3. Provide performance optimization: GUAVA's PrimitiveTypes module is committed to providing high -performance basic data type processing functions.It uses some optimization technologies and algorithms to improve the operating efficiency and performance of basic data types. Example: Here are some Java code examples used in the PrimitiveTypes module of Guava: Example: 1. Basic data types: Ints intvalue = ints.frombytearray (bytearray); // convert the byte array to int value Longs longvalue = longs.fromhexstring (hexstring); // convert the hexadecimal strings to Long value Floats Floatvalue = Floats.tryParse (FloatString); // Convert the string to Float value, and if the conversion fails, return NULL 2. Basic type conversion: int intvalue = ints.checkedcast (longvalue); // convert the loong value to int, if it exceeds the range, throw out iLlegalaLARGuMemexception abnormalities double doubleValue = doubles.constraintorange (floatvalue, min, max); // limit the float value to the specified range and convert it to the double value 3. Performance optimization: int[] intArray = {1, 2, 3, 4, 5}; int Sum = ints.sum (Intarray); // Calculate the sum of the integer array, use optimized algorithms to implement, and better performance when processing large arrays Summarize: Guava's PrimitiveTypes module has made the basic data types more simple and efficient through the principles of packaging basic data types, supporting basic type conversion, and providing performance optimization.In daily encoding, we can use these functions to better process the operation of basic data types and improve the readability and performance of code.
