There are many places in the world where Java people are more likely to be than C + +.(8) Java can make you look more like a hoof animal (ox).0x02Here are some of the problems that ACM-ICPC players have encountered with Java programming at first:1. Basic input and output:(1) The New scanner class for JDK 1.5.0 provides a good basis for input and is simply for ACM-ICPC.The general usage is

Standard Io Library: The standard library defines a family of types and supports reading and writing files, control windows, and other devices. It also enables string objects to operate like files. Use inheritance. Stream: a description that transmits data from the source to the target in byte mode. Input stream: refers to the transmission of bytes from the input device to the memory; Output stream: refers to the transmission of bytes from the memory to the output device; Header file correspon

, according to read the character conversion state, enter a state, when the next character read does not conform to the current state of the type, do not read the character, and read the end of the string, when it is a type. After judging the string, repeat the operation again until all characters are read. When the state of need to judge is added, it becomes the lexical analysis conversion diagram of tiny. Iv.

Chapter 3: strings, vectors, and arrays, and vectors of 2017.11.12 3.1 namespace using Declaration Std: cin indicates that the content is read from the standard input. Here, the scope operator (: :) is used to indicate that the compiler looks for the right name from the scope shown in the operator's left name. Using declaration is the safest way. The using Declaration has the following format: Using namespace: name; For example: # Include Using std:
