java通过for循环获取list中想要的内容

获取list有几条内容 通过循环取值 当i小于list.size时i加一

 List<nrbean> li=new ArrayList<nrbean>();// po=null;
		        li=dd.chakan(data);
		      String jsonObject="";
		      ///通过下面方法能取出list中想要的数值
		       for(int i=0;i<li.size();i++){   
		       int id;
		        	nrbean nb=li.get(i);
			  
			  
			   System.out.print("------------"+nb.getId());
			     //   }

i表示当前是第几条list
将第i条内容赋给对象nb

nrbean nb=li.get(i);

在通过对象nb get nb中的内容
下面是nrbean

package bean;
