可以使用Files类的exists()方法来检查文件是否存在。以下是一个示例代码: importjava.nio.file.Files;importjava.nio.file.Path;importjava.nio.file.Paths;publicclassCheckFile{publicstaticvoidmain(String[]args){StringfilePath="path_to_your_file";// 文件路径Pathpath=Paths.get(filePath);if(Files.exists(...
Learn to check if a file exists or a directory exists in given path in Java. Also check is file is readable, writable or executable. Learn to test if a file or a directory exists in a given path using Java standard IO and NIO APIs. 1. UsingFiles.exists()andFiles.notExists() Java ...
There is one more issue with only using theexists()method to check if a file exists or not. Because, it returns a true value if we accidentally specify a directory. So we have to use the methodisDirectory()also to make sure that the given argument is a file but not a directory. The...
section 步骤1:创建File对象 CreateFileObject(创建File对象) --> CheckFileExistence(检查文件是否存在) --> | section 步骤2:读取文件内容 OpenFile(打开文件) --> ReadFile(读取文件内容) --> | section 步骤3:判断文件内容是否为空 CheckContent(判断文件内容是否为空) --> PrintResult(输出判断结果) 步骤...
使用file.exists()方法即可检测file对象是否为一个有效的路径或文件夹exists语法: public boolean exists() 返回值说明 true:文件或文件夹已经存在 false:此路径不表示文件也不表示文件夹 异常说明 抛出SecurityException:SecurityManager.checkRead(String)时
2. Usingjava.nio.file.Files To check if a file or directory exists, we can leverage theFiles.exists(Path)method. As it’s clear from the method signature, we should firstobtain aPathto the intended file or directory. Then we can pass thatPathto theFiles.exists(Path)method: ...
在Java中,可以使用File类的exists()方法来判断某个路径是否存在。示例如下: import java.io.File; public class CheckPathExists { public static void main(String[] args) { String path = "/path/to/file/or/directory"; File file = new File(path); if(file.exists()) { System.out.println("The ...
在Java中可以使用File类的exists()方法和isDirectory()方法来判断文件夹是否存在。 示例代码如下: import java.io.File; public class CheckFolderExists { public static void main(String[] args) { String folderPath = "path/to/folder"; File folder = new File(folderPath); if (folder.exists() && ...
*/publicvoidcheckDirExists(File file){if(file.exists()){if(file.isDirectory()){LOG.info("目录存在");}else{LOG.info("同名文件存在, 不能创建");}}else{LOG.info("目录不存在,创建目录");file.mkdir();}}} exists() public boolean exists()测试此抽象路径名表示的文件或目录是否存在。
(StandardCharsets.UTF_8); // 将字节序列转换为字符串 String encodedFilePath = new String(filePathBytes, StandardCharsets.ISO_8859_1); // 创建File对象并检查文件是否存在 File file = new File(encodedFilePath); if (file.exists()) { System.out.println("文件存在"); } else...
