以下示例显示java.io.PipedReader.ready()方法的用法。
package com.jc2182;
import java.io.*;
public class PipedReaderDemo {
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
reader.connect(writer);
// write something
writer.write(70);
writer.write(71);
// check if reader is ready to read
System.out.println("" + reader.ready());
// print the char array
for (int i = 0; i < 2; i++) {
System.out.println("" + (char) reader.read());
}
} catch (IOException ex) {
ex.printStackTrace();
}
}
}
