Java创建文件的方法有以下几种:
示例代码:
File file = new File("path/to/file.txt"); try { boolean success = file.createNewFile(); if (success) { System.out.println("文件创建成功"); } else { System.out.println("文件已存在"); } } catch (IOException e) { e.printStackTrace(); }
示例代码:
String content = "Hello, World!"; byte[] bytes = content.getBytes(); try { FileOutputStream fos = new FileOutputStream("path/to/file.txt"); fos.write(bytes); fos.close(); System.out.println("文件创建成功"); } catch (IOException e) { e.printStackTrace(); }
示例代码:
String content = "Hello, World!"; try { BufferedWriter writer = new BufferedWriter(new FileWriter("path/to/file.txt")); writer.write(content); writer.close(); System.out.println("文件创建成功"); } catch (IOException e) { e.printStackTrace(); }
这些方法可以根据具体的需求选择适合的方法来创建文件。
