There are several ways to read an InputStream and convert it to a String in Java. One way is to use the BufferedReader and InputStreamReader classes to read the InputStream line by line, and use a StringBuilder to construct the final String:

Just like there are many ways for writing String to text file, there are multiple ways to read String form File in Java. You can use FileReader, BufferedReader, Scanner, and FileInputStream to read text from file. One thing to keep in mind is character encoding. You must use correct ...
If you have ajava.io.InputStreamobject, how should you process that object and produce aString? Suppose I have anInputStreamthat contains text data, and I want to convert it to aString, so for example I can write that to a log file.PartyCity Feedback ...
In Java programming, there are situations where we need to convert an InputStream object into a String. This can be useful when we want to read the content of a file, network response, or any other data source that is accessed through an InputStream and process it as a String. In this...
下面是一个完整的示例代码,演示如何使用Java的BufferedReader读取InputStream: importjava.io.*;publicclassMain{publicstaticvoidmain(String[]args){try{FileInputStreamfis=newFileInputStream("input.txt");InputStreaminputStream=newBufferedInputStream(fis);InputStreamReaderisr=newInputStreamReader(inputStream);Buffer...

NIOStream oriented Buffer oriented Blocking IO Non blocking IO Selectors 2.2 面向流与面向缓冲 Java NIO和IO之间第一个最大的区别是,IO是面向流的,NIO是面向缓冲区的。 Java IO面向流意味着每次从流中读一个或多个字节,直至读取所有字节,它们没有被缓存在任何地方。此外,它不能前后移动流中的数据。如果需要...
