装饰模式--奖金计算（C#）与JAVA IO流

奖金分类，对于个人有当月奖金、个人累计奖金、个人业务增长奖金、及时回款奖金、限时成交加码奖金等；对于业务主管或者是业务经理，除了个人奖金外，还有团队累积奖金、团队业务增长奖金、团队盈利奖金等。 计算公式也有不同 计算奖金金额的基数也有不同 奖金的计算方式会经常变化。要适于调整和修改。

利用装饰模式：

简略实现一下，有时间再精致一下代码。

太丑了这个图...

JAVA中的Io流

 

import java.io.BufferedInputStream;
import java.io.DataInputStream;
import java.io.FileInputStream;
import java.io.IOException;

public class IoTestOne {

	public static void main(String[] args) throws IOException {
		// TODO Auto-generated method stub
		DataInputStream cin = null;
		try {
			cin = new DataInputStream(new BufferedInputStream(new FileInputStream("D:/Io.txt")));
			byte bs[] = new byte[cin.available()];
			cin.read(bs);
			String content = new String(bs);
			System.out.println(content);
		} finally {
			cin.close();//
		}
	}

}

改写后

import java.io.IOException;
import java.io.OutputStream;

public class EncryptOutputStream extends OutputStream {
	private OutputStream os=null;
	
	public EncryptOutputStream(OutputStream os) {
		super();
		this.os = os;
	}

	@Override
	public void write(int b) throws IOException {
		// TODO Auto-generated method stub
		b=b+2;
		if(b>=97+26)
		{
			b-=26;
		}
		this.os.write(b);//重写这个函数
	}

}

import java.io.BufferedOutputStream;
import java.io.DataOutputStream;
import java.io.FileNotFoundException;
import java.io.FileOutputStream;
import java.io.IOException;

public class IoTest {

	public static void main(String[] args) throws IOException {
		// TODO Auto-generated method stub
		DataOutputStream cout = new DataOutputStream(
				new BufferedOutputStream(new EncryptOutputStream(new FileOutputStream("D:/Io.txt"))));
		cout.write("abcdd".getBytes());
		cout.close();
	}

}
