所以Java中有字节流和字符流,以及在字符流和字节流之间进行转换的转换流,如InputStreamReader和OutputStreamReader,这两个类是字节流和字符流之间的适配器类,承担了编码转换的任务;对于C程序员来说,要完成这样的编码转换恐怕要依赖于union(联合体/共用体)共享内存的特征来实现了。 23、抽象类(abstract class)和接口(...

A.InputStreamReader B.BufferedReader C.Writer D.PipedInputStream 解析 本题主要考察字符流和字节流。字符流是字节流根据字节流所要求的编码集解析获得的,可以理解为字符流=字节流+编码集,字符流处理的单元为2个字节的Unicode字符,分别操作字符、字符数组或字符串,而字节流处理单元为1个字节,操作字节和字节数组。

Applications do not need to implement security themselves. Rather, they can request security services from the Java platform. Security services are implemented in providers (see below), which are plugged into the Java platform via a standard interface. An application may rely on multiple independent...
This document describes what you need to do in order to integrate your provider into Java SE so that algorithms and other services can be found when Java Security API clients request them.
In older versions of Java, you had to set your CLASSPATH to include “.”, even to run a simple program from the current directory; this is no longer true on current Java implementations. Sun/Oracle’s javac compiler is the official reference implementation. There were several alternative ...
