Java read text files tutorial shows how to read text files in Java. We use build-in tools including FileReader, InputStreamReader, and Scanner.
我们可以使用Files类的readAllLines()方法来一次性读取整个文件内容,并将其返回为一个字符串列表。以下是使用Files类的代码示例: AI检测代码解析 importjava.io.IOException;importjava.nio.file.Files;importjava.nio.file.Paths;importjava.util.List;publicclassReadTextFile{publicstaticvoidmain(String[]args){Stringf...
