InputStreamReader将从文件中读到的字节流转换成字符流,相似的,OutputStreamWriter将字符流转换为字节写入到文件中。 InputStreamReader有两个构造函数,第一个是InputStreamReader(InputStreamin),第二个是InputStreamReader(InputStreamin,StringcharsetName)。 第一个能够自适应的检测文本的内容选择相应的字符集,例如: pu...
而BufferedWriter直接继承于java.io.Writer,看它的构造函数与用法,明显使用了装饰设计模式, 这意味着我们要使用它,就必须给他一个Writer才可以,在该文章中我们假设给定的Writer就是FileWriter。 二、两个类的用法 1.FileWriter FileWriter fw = null; try { fw = new FileWriter("c:/123456"); fw.write("012345...
可见,PrintWriter可以用来包装Writer的任意子类,当包装OutputStream时,默认包装一层BufferWriter。当然也可以将File或者File路径作为参数,实质上一样,如下所示: public PrintWriter(String fileName) throws FileNotFoundException { this(new BufferedWriter(new OutputStreamWriter(new FileOutputStream(fileName))), false)...
当执行输出时,程序相当于依次把“水滴”放入到输出流的水管中,输出流同样采用隐示指针来标识当前水滴即将放入的位置,每当程序向OutputStream或者Writer里面输出一个或者多个水滴后,记录指针自动向后移动。 以上显示了java Io的基本概念模型,除此之外,Java的处理流模型则体现了Java输入和输出流设计的灵活性。处理流的功能...

implementation'com.github.javasync:RxIo:1.2.5' Usage Kotlin examples: Java examples: TheAsyncFiles::lines()returns a reactivePublisherwhich is compatible with Reactor or RxJava streams. Thus we can use the utility methods of ReactorFluxto easily operate on the result ofAsyncFiles::lines(). In...
writer.flush(); writer.close(); Theflush()method "flushes" the contents into the file andclose()permanently closes the stream. Note:If you use thetry-with-resourcessyntax, it'll flush and close the stream automatically. Conclusion In this article, we've shown some common methods for writing...
