split拆分、组合id字符串

String newDeptIds="";
		String oldDeptIds="1,2,3,4,5,6";
		String[] deptIds = oldDeptIds.split(",");
		
		for(int i=1;i<deptIds.length;i++)
		{
			if(i==deptIds.length-1)
			{
				newDeptIds+="00"+deptIds[i];
			}
			else
			{
				newDeptIds+="00"+deptIds[i]+",";
			}
		}
		System.out.println("改写后的newDeptIds"+ newDeptIds);
