定義http協議頭

package org.meal.util;

public class BLOCK_DATA {

	private String _mtype;         //主類型 2字符長度
    private String _subtype;       //次類型     2字符長度       
    private String shopid;  //五位商戶號
    private String dataLen;      
    private String _DataBody;
    
    public String BLOCK2String(BLOCK_DATA bh)
    {
    	String tem="";
    	tem+=_subtype;
    	tem+=_mtype;
    	tem+=shopid;
    	tem+=dataLen;
    	tem+=_DataBody;
		return tem;
    	
    }
    

    public String chek;//校驗數據位
    
    
	public String getShopid() {
		return shopid;
	}

	public void setShopid(String shopid) {
		this.shopid = shopid;
	}

	public String get_mtype() {
		return _mtype;
	}

	public void set_mtype(int _mtype) {
		this._mtype = String.format("%02d", _mtype);
	}

	public String get_subtype() {
		return _subtype;
	}

	public void set_subtype(int _subtype) {
		this._subtype =String.format("%02d", _subtype);;
	}

	public String getDataLen() {
		return dataLen;
	}

	public void setDataLen(String dataLen) {
		this.dataLen = dataLen;
	}

	public String get_DataBody() {
		return _DataBody;
	}

	public void set_DataBody(String _DataBody) {
		this._DataBody = _DataBody;
	}

	public String getChek() {
		return chek;
	}

	public void setChek(String chek) {
		this.chek = chek;
	}
    
    
}

其次定義常量
package org.meal.util;

public final  class Constants {

	//私有構造方法
    private Constants() {}
    public static final int LIVE = 1;
    public static final int BYE = 2;
    public static final int REFRESH = 3; //刷新功能
    public static final int STOP = 4;
    public static final int DATA = 5;  //數據
    public static final int PRINT = 6; //打印
    public static final int MENU = 7;  //菜單
}
