以下示例显示java.io.PipedInputStream.available()方法的用法。
package com.jc2182;
import java.io.*;
public class PipedInputStreamDemo {
public static void main(String[] args) {
// create a new Piped input and Output Stream
PipedOutputStream out = new PipedOutputStream();
PipedInputStream in = new PipedInputStream();
try {
// connect input and output
in.connect(out);
// write something
out.write(70);
out.write(71);
// print how many bytes are available
System.out.println("" + in.available());
// read what we wrote
for (int i = 0; i < 2; i++) {
System.out.println("" + (char) in.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-
