out.java

是一个综合开发程序,可以做为系统研究人员的参考

public class out{
	public static void main(String[] args){
		byte[] buff =new byte[20];
		String info =null;
		int pos =0;
		int ch = 0;
		System.out.println("please input your letter:");
		
	  while(true){
	  	try{
	  		ch=System.in.read();
	  	}
	  	catch(Exception e){
	  		e.printStackTrace();
	  		
	  	}
	  	switch(ch){
	  		case '\r': break;
	  		case '\n':
	  		info = new String(buff,0,pos);
	  		if (info.equals("bye")){
	  			return;
	  		}
	  		else{
	  		System.out.println(info);
	  		pos = 0;
	  		break;	
	  		}
	  		default:
	  		buff[pos++] =(byte) ch;
	  	}
	  }
	}
