字节流、字符流通过管道进行线程间通信

字节流实现通信

public class WriteData {

	public void writeMethod(PipedOutputStream out) {
		try {
			System.out.println("write :");
			for (int i = 0; i < 300; i++) {
				String outData = "" + (i + 1);
				//写数据write()
				out.write(outData.getBytes());
				System.out.print(outData);
			}
			System.out.println();
			out.close();
		} catch (IOException e) {
			e.printStackTrace();
		}
	}
}

public class ReadData {

	public void readMethod(PipedInputStream input) {
		try {
			System.out.println("read  :");
			//读取数据
			byte[] byteArray = new byte[20];
			int readLength = input.read(byteArray);
			
			while (readLength != -1) {
				String newData = new String(byteArray, 0, readLength);
				System.out.print(newData);
				//读取数据read（）
				readLength = input.read(byteArray);
			}
			System.out.println();
			input.close();
		} catch (IOException e) {
			e.printStackTrace();
		}
	}
}

public class ThreadWrite extends Thread {

	private WriteData write;
	private PipedOutputStream out;

	public ThreadWrite(WriteData write, PipedOutputStream out) {
		super();
		this.write = write;
		this.out = out;
	}

	@Override
	public void run() {
		write.writeMethod(out);
	}

}

public class ThreadRead extends Thread {

	private ReadData read;
	private PipedInputStream input;

	public ThreadRead(ReadData read, PipedInputStream input) {
		super();
		this.read = read;

	}

	@Override
	public void run() {

	}
}

public static void main(String[] args) {

		try {

		try {
			WriteData writeData = new WriteData();
			ReadData readData = new ReadData();
                        
			PipedReader inputStream = new PipedReader();
			PipedWriter outputStream = new PipedWriter();

			// inputStream.connect(outputStream);
			outputStream.connect(inputStream);

			ThreadRead threadRead = new ThreadRead(readData, inputStream);
			threadRead.start();

			Thread.sleep(2000);

			ThreadWrite threadWrite = new ThreadWrite(writeData, outputStream);
			threadWrite.start();

		} catch (IOException e) {
			e.printStackTrace();
		} catch (InterruptedException e) {
			e.printStackTrace();
		}
