在以上代码中,readFileAsString()方法使用Files.readAllBytes()方法读取文件的所有字节内容,并使用new String()构造函数将字节内容转换为字符串。 3. 状态图 下面是使用 Mermaid 语法绘制的 Java 读取本地文件状态图: StartReadFileConverttoStringEnd 以上状态图描述了 Java 读取
在Java中,可以使用BufferedReader类来打开txt文件。 importjava.io.BufferedReader;importjava.io.FileReader;importjava.io.IOException;publicclassReadFileToString{publicstaticStringreadFileAsString(StringfilePath)throwsIOException{StringBuilderstringBuilder=newStringBuilder();BufferedReaderbufferedReader=newBufferedReader(ne...
During Java application development, we need to read the contents of a file into a string in many situations such as processing configuration files, parsing data, or handling text-based resources. In this Java tutorial, we will explore different ways toread a text file into Stringin Java from ...

String line = null; while((line = br.readLine()) != null){ System.out.println(line); } 2、写文件: BufferWriter(Writer out) BufferWriter的参数类型可为:FileWriter、OutputStreamWriter FileWriter(String fileName) FileWriter(File file)
buffer.asCharBuffer().flip(); // 将缓冲区的内容转换为字符缓冲区,准备读取字符串 String line = charset.decode(buffer).toString(); // 将字符缓冲区的内容解码为字符串,并去除换行符等特殊字符 System.out.println(line); // 输出字符串内容,即一行文本 ...
