List根据下标删除对象

@Data
public class ResResult {
    private String combineId;//检测组合
    private String sid;//样本号
    private String itemCode;//项目代码
    public ResResult(String combineId, String sid, String itemCode) {
        this.combineId = combineId;
        this.sid = sid;
        this.itemCode = itemCode;
    }
    public ResResult( ) {
    }
}

@Test
public void contextLoads() {
    List<ResResult> result = new ArrayList<ResResult>();
    ResResult R1 = new ResResult("ts","111","hcg");
    ResResult R2 = new ResResult("ts","222","afp");
    ResResult R3 = new ResResult("ts","333","papp_a");
    result.add(R1);
    result.add(R2);
    result.add(R3);
    result.remove(1);//根据下标删除第2个对象
    //ResResult resResult = result.get(1);
   //result.remove(resResult);//删除ii对应的
    result.set(1,new ResResult("ts","222333","afp"));//覆盖列表中的第二个对象
