Java NIO Files：Paths.get创建：PathOps.java

PathOps.java

• Path p = Paths.get(C:/data/../data/test.txt);
• System.out.println(p.getFileName()); // test.txt
• System.out.println(p.getParent()); // C:/data/../data
• System.out.println(p.normalize()); // C:/data/test.txt
• System.out.println(p.toAbsolutePath());

🔍存在性判断

• exists(path)　文件是否存在
• notExists(path)　是否不存在
• isRegularFile(path)　是否常规文件
• isDirectory(path)　是否目录
