在上面的示例代码中,readFileToString方法接受文件路径作为参数,并返回文件内容的字符串表示。我们使用BufferedReader逐行读取文件,将每一行添加到StringBuilder中。最后,我们将StringBuilder转换为字符串并返回。 要在main方法中调用readFileToString方法,您需要提供文件的实际路径。请将"path/to/your/file.txt"替换为您要读...

java中有四种将文件的内容读取成字符串方式一：Java code / 以字节为单位读取文件，常用于读二进制文件，如图片、声音、影像等文件。当然也是可以读字符串的。/ /* 貌似是说网络环境中比较复杂，每次传过来的字符是定长的，用这种方式？*/ public String readString1(){ try { //FileInputStream ...
