本文详细介绍了如何使用Java进行网络请求，获取并解析数据。通过实现LeftInter接口的LeftClass类，利用Http工具类执行GET请求，获取LeftBean和RightBean类型的数据，并通过回调机制处理请求成功或失败的情况。在Presenter层，LeftPresenterClass实现了业务逻辑，调用Model层的方法获取数据。

package bwie.com.day8_test.model;

public interface LeftInter
{
   public void getLeftData(String url,CallBacks callBacks);
    public void getRightData(String url,CallBacks callBacks);
   interface  CallBacks{
       void LoadSuccess(Object data);
       void LoadFail();
   }
}

package bwie.com.day8_test.model;

import bwie.com.day8_test.bean.LeftBean;
import bwie.com.day8_test.bean.RightBean;
import bwie.com.day8_test.http.Http;

public class LeftClass implements LeftInter
{
    @Override
    public void getLeftData(String url, final CallBacks callBacks) {
        Http.getInstance().doGet(url, LeftBean.class, new Http.NetCallBack() {
            @Override
            public void onSuccess(Object o) {
                callBacks.LoadSuccess(o);
            }
            @Override
            public void onFailure(Exception e) {

            }
        });
    }
    @Override
    public void getRightData(String url, final CallBacks callBacks) {
        Http.getInstance().doGet(url, RightBean.class, new Http.NetCallBack() {
            @Override
            public void onSuccess(Object o) {
                callBacks.LoadSuccess(o);
            }

            @Override
            public void onFailure(Exception e) {

            }
        });

    }
}

package bwie.com.day8_test.presenter;

public interface LeftPresenter
{
    void  getLeftPresenterData();
}

package bwie.com.day8_test.presenter;

import bwie.com.day8_test.api.Api;
import bwie.com.day8_test.fragment.FenleiFragment;
import bwie.com.day8_test.model.LeftClass;
import bwie.com.day8_test.model.LeftInter;

public class LeftPresenterClass implements LeftPresenter
{

    private final LeftClass leftClass;
    FenleiFragment fenleiFragment;
    public LeftPresenterClass(FenleiFragment fenleiFragment)
    {
        //初始化model
        leftClass = new LeftClass();
        //初始化view
        this.fenleiFragment =fenleiFragment;

    }

    @Override
    public void getLeftPresenterData() {
        leftClass.getLeftData(Api.FENlEI, new LeftInter.CallBacks() {
            @Override
            public void LoadSuccess(Object data) {
                 fenleiFragment.getLeftData(data);
            }

            @Override
            public void LoadFail() {

            }
        });
    }
}
