以下示例显示java.io.PipedWriter.close()方法的用法。
package com.jc2182;
import java.io.*;
public class PipedWriterDemo {
public static void main(String[] args) {
// create a new Piped writer and reader
PipedWriter writer = new PipedWriter();
PipedReader reader = new PipedReader();
try {
// connect the reader and the writer
writer.connect(reader);
// write something
writer.write(70);
writer.write(71);
// close the writer
System.out.println("Closing writer...");
writer.close();
System.out.println("Writer closed.");
// print what we wrote
for (int i = 0; i < 2; i++) {
System.out.println("" + (char) reader.read());
}
} catch (IOException ex) {
ex.printStackTrace();
}
}
}
让我们编译并运行以上程序,这将产生以下结果-
Closing writer...
Writer closed.
