java 8 parallel stream

streamThe print stream only has no input stream for the output stream, and the printwriter and printstream are for character bytes respectively.The two classes provide the overloaded print and println methods for output of multiple data types.Output operations of printwriter and printstream will not throw an exceptionPrintwriter and printstream have the automati

too many forced type conversions. Compiler Optimization: Java 8 adds the parameter name of the method to the bytecode so that the parameter name can be obtained through reflection at runtime. You only need to use the-parameters parameter during compilation. Parallel Array: Supports parallel processing of arrays, mai

The processing object is different: The byte stream can handle all types of data (slices, AVI, etc.), while the character stream can only handle data of the type of characters. BYTE stream:
