The classFiles, as a part of thejava.NIOpackage, contains alines()method that producesStream<String>or a stream of string from a text file. Let’s try to convert the file contents into Java string using Stream
OutputStream bos1=newBufferedOutputStream(fos,2048);// 第二次读流int len;byte[]bytes=newbyte[2048];while((len=in.read(bytes,0,2048))!=-1){bos1.write(bytes,0,len);}bos1.flush();bos1.close();
In this Java tutorial, we will explore different ways toread a text file into Stringin Java from traditionalBufferedReader, new APIs in Java 8 and 11 to third-party libraries such as Apache Commons Lang and Guava. 1. UsingFiles.readString()– Java 11 With the new methodreadString()introduced...

In Java 7+, Files.readAllLines() can be used to read a file into a List<String> object. Apart from using this method for reading a file line by line in Java, you can also use it to convert a file into a string as shown below: try { // read file to list List<String> lines ...
When calling this property, theResourceManager.GetString()function is invoked. ThisResourceManagerclass is in turn declared in the same file as a read-only property, which returns an instance of theResourceManagerclass, from theSystem.Resourcesnamespace: ...
C = textscan(fileID,formatSpec) reads data from an open text file into a cell array, C. The text file is indicated by the file identifier, fileID. Use fopen to open the file and obtain the fileID value. When you finish reading from a file, close the file by calling fclose(fileID...
