将时间段转化为48位二进制编码

时间段格式：01:00-12:00/13:00-21:30(英文输入法)

代码：

/**

	 * 构造48位营业时间二进制码
	 * @param timeStr
	 * @return
	 */
	public String createBuinessPeriodBin(String timeStr){
		try {
			String[] strs = timeStr.split("/"); 
			Character[] btb = new Character[48]; 
			for(String str : strs) { 
			String[] s = str.split("-"); 
			String[] b1 = s[0].split(":"); 
			String[] b2 = s[1].split(":"); 
			Integer i1 =Integer.valueOf(b1[0])*2; 
			Integer i2 = Integer.valueOf(b1[1]); 
			if(i2 >= 30){ i2 = 1;} 
			else{ 
			i2=0; 
			} 
			Integer i3 =Integer.valueOf(b2[0])*2; 
			Integer i4 = Integer.valueOf(b2[1]); 
			if(i4 >= 30){ i4 = 1;} 
			else{ 
			i4=0; 
			} 
			for(int m =(i1+i2); m < (i3+i4); m ++ ){ 
			btb[m] = '1'; 
			} 
			} 
			for(int i =0; i < 48; i++) { 
			if(btb[i] == null) { 
			btb[i] ='0'; 
			} 
			} 
			StringBuilder sb = new StringBuilder(); 
			for(Character b : btb) { 
			sb.append(b); 
			} 
			return sb.toString();
		} catch (NumberFormatException e) {
			e.printStackTrace();
		}
		return "";
