Java導出List集合到txt文件中——（四）

有時候，需要將數據以一定格式導出到txt文件中。利用Java的IO可以輕松的導出數據到txt中。

package Action.txt;

import java.io.BufferedWriter;
import java.io.File;
import java.io.FileOutputStream;
import java.io.OutputStreamWriter;
import java.io.Writer;
import java.util.ArrayList;
import java.util.List;

import org.junit.Test;

import bean.Question;

/*[題干]防抱死制動系統（ABS）在什么情況下可以最大限度發揮制動器效能?
[類型]單選
[選項]{A:間歇制動},{B:持續制動},{C:緊急制動},{D:緩踏制動踏板}
[答案]C
[解析]ABS的目的就是為了防止剎車的時候一腳踩死，導致翻車什么的。 不過剎車剎死就比較慢（速度N快的時候），效果等於踩下剎車，再松下剎車，反復幾次！*/
public class ExportTxtPaper {

    private static File outFile = new File("test.txt");

    /**
     * 產生單選模板
     * 
     * @param num
     *            單選數量
     */
    public static void  exportTxtPaper(List<Question> list) {

        Writer out;
        try {
            out = new BufferedWriter(new OutputStreamWriter(new FileOutputStream(outFile,true), "utf-8"), 10240);
            for (int i = 0; i < list.size(); i++) {
                out.write(
                        "[題干]"+list.get(i).getTimu()+
                        "\r\n[類型]"+list.get(i).getLeixing()
                        + "\r\n[A選項]"+list.get(i).getAxuanxiang()
                        + "\r\n[B選項]"+list.get(i).getBxuanxiang()
                        + "\r\n[C選項]"+list.get(i).getCxuanxiang()
                        + "\r\n[D選項]"+list.get(i).getDxuanxiang()
                        + "\r\n[答案]"+list.get(i).getDaan()
                        + "\r\n[解析]"+list.get(i).getJiexi()+"\r\n");
                out.write("\r\n");
            }
            out.flush();
            out.close();
        } catch (Exception e1) {
            // TODO Auto-generated catch block
            e1.printStackTrace();
        }
    }

    
    /**
     * 測試產生模板
     */
    @Test
    public void test1(){
        
        List<Question> list = new ArrayList<>();
        list.add(new Question("你喜歡吃什么", "單選", "老司機", "方便嗎", "辣條", "牛奶", "老司機", "我是老司機"));
        list.add(new Question("你喜歡吃什么", "單選", "老司機", "方便嗎", "辣條", "牛奶", "老司機", "我是老司機"));
        list.add(new Question("你喜歡吃什么", "單選", "老司機", "方便嗎", "辣條", "牛奶", "老司機", "我是老司機"));
        list.add(new Question("你喜歡吃什么", "單選", "老司機", "方便嗎", "辣條", "牛奶", "老司機", "我是老司機"));
        list.add(new Question("你是人", "判斷", "", "", "", "", "是", "我是老司機"));
        list.add(new Question("你是人", "判斷", "", "", "", "", "是", "我是老司機"));
        ExportTxtPaper .exportTxtPaper(list);
    }
}
