简介
I/O 操作的纽带。 (机器翻译)
final var path = Path.of("R:", "java-work", "test.data");
System.out.println(path); // R:\java-work\test.data
Channel channel;
try (final var fc = FileChannel.open(path,
StandardOpenOption.CREATE, StandardOpenOption.WRITE)) {
channel = fc;
System.out.println(channel.isOpen()); // true
}
System.out.println(channel.isOpen()); // false
Methods
void close ()
关闭此频道。 (机器翻译)
final var path = Path.of("R:", "java-work", "test.data");
System.out.println(path); // R:\java-work\test.data
Channel channel;
try (final var fc = FileChannel.open(path,
StandardOpenOption.CREATE, StandardOpenOption.WRITE)) {
channel = fc;
System.out.println(channel.isOpen()); // true
}
System.out.println(channel.isOpen()); // false
// An example without a try-with-resources statement.
final var path = Path.of("R:", "java-work", "test.data");
System.out.println(path); // R:\java-work\test.data
final Channel channel = FileChannel.open(path,
StandardOpenOption.CREATE, StandardOpenOption.WRITE);
try {
System.out.println(channel.isOpen()); // true
} finally {
channel.close();
}
System.out.println(channel.isOpen()); // false
boolean isOpen ()
告知该通道是否打开。 (机器翻译)
final var path = Path.of("R:", "java-work", "test.data");
System.out.println(path); // R:\java-work\test.data
Channel channel;
try (final var fc = FileChannel.open(path,
StandardOpenOption.CREATE, StandardOpenOption.WRITE)) {
channel = fc;
System.out.println(channel.isOpen()); // true
}
System.out.println(channel.isOpen()); // false
// An example without a try-with-resources statement.
final var path = Path.of("R:", "java-work", "test.data");
System.out.println(path); // R:\java-work\test.data
final Channel channel = FileChannel.open(path,
StandardOpenOption.CREATE, StandardOpenOption.WRITE);
try {
System.out.println(channel.isOpen()); // true
} finally {
channel.close();
}
System.out.println(channel.isOpen()); // false
