简介
final var file = Path.of("R:", "java-work", "aaa.txt");
System.out.println(file); // R:\java-work\aaa.txt
System.out.println(Files.notExists(file)); // true
try {
System.out.println("-- delete --");
Files.delete(file);
} catch (NoSuchFileException e) {
System.out.println(e);
}
// Result
// ↓
//-- delete --
//java.nio.file.NoSuchFileException: R:\java-work\aaa.txt
final var src = Path.of("R:", "java-work", "aaa.txt");
final var dst = Path.of("R:", "java-work", "bbb.txt");
System.out.println(src); // R:\java-work\aaa.txt
System.out.println(dst); // R:\java-work\bbb.txt
System.out.println(Files.notExists(src)); // true
System.out.println(Files.notExists(dst)); // true
try {
System.out.println("-- copy --");
Files.copy(src, dst);
} catch (NoSuchFileException e) {
System.out.println(e);
}
// Result
// ↓
//-- copy --
//java.nio.file.NoSuchFileException: R:\java-work\aaa.txt

NoSuchFileException (String file)
final var e = new NoSuchFileException("aaa.txt");
System.out.println(e); // java.nio.file.NoSuchFileException: aaa.txt
System.out.println(e.getFile()); // aaa.txt
NoSuchFileException (String file, String other, String reason)
final var e = new NoSuchFileException("aaa.txt", "bbb.txt", "Reason!");
System.out.println(e); // java.nio.file.NoSuchFileException: aaa.txt -> bbb.txt: Reason!
System.out.println(e.getFile()); // aaa.txt
System.out.println(e.getOtherFile()); // bbb.txt
System.out.println(e.getReason()); // Reason!
System.out.println(e.getMessage()); // aaa.txt -> bbb.txt: Reason!
