正文之前

一天打魚九天曬網(wǎng)的畢業(yè)設(shè)計。感覺快要迎來中期檢查了纪隙。所以有點(diǎn)慌這兩天赊豌，哆哆嗦嗦的把一部分代碼寫完了（大部分都是抄，小部分自己改）绵咱。所以為了我的簡書存活碘饼，到底要把今天寫的一個東西放了上來。

正文

其實(shí)沒什么好說的悲伶，就是一個文本讀取類艾恼。當(dāng)然，為了體現(xiàn)效果麸锉，我還這幾在里面留了一個測試的數(shù)據(jù)钠绍。如果本身有數(shù)據(jù)的話把測試的數(shù)據(jù)刪掉就可以了。這個基本上是通用吧花沉，很多地方都可以用的哦柳爽。

import java.io.*;

public class ReadData {
    public Object[][] ReadData() throws IOException {
        Object[][] rawData = new Object [][]{
                { "<30  ", "High  ", "No ", "Fair     ", "0" },
                { "<30  ", "High  ", "No ", "Excellent", "0" },
                { "30-40", "High  ", "No ", "Fair     ", "1" },
                { ">40  ", "Medium", "No ", "Fair     ", "1" },
                { ">40  ", "Low   ", "Yes", "Fair     ", "1" },
                { ">40  ", "Low   ", "Yes", "Excellent", "0" },
                { "30-40", "Low   ", "Yes", "Excellent", "1" },
                { "<30  ", "Medium", "No ", "Fair     ", "0" },
                { "<30  ", "Low   ", "Yes", "Fair     ", "1" },
                { ">40  ", "Medium", "Yes", "Fair     ", "1" },
                { "<30  ", "Medium", "Yes", "Excellent", "1" },

        File file = new File("/Users/zhangzhaobo/IdeaProjects/Graduation_Design/src/data.txt");  //存放數(shù)組數(shù)據(jù)的文件

        FileWriter DataToTXT = new FileWriter(file);  //文件寫入流
        int row=0;
        //將數(shù)組中的數(shù)據(jù)寫入到文件中。每行各數(shù)據(jù)之間TAB間隔
        for(int i=0;i<rawData.length;i++){
            for(int j=0;j<rawData[0].length;j++){
                DataToTXT.write(rawData[i][j]+"\t");
            }
            row++;
            DataToTXT.write("\r\n");
        }
        DataToTXT.close();

        BufferedReader in = new BufferedReader(new FileReader(file));
        String line;  //一行數(shù)據(jù)
        //逐行讀取碱屁，并將每個數(shù)組放入到數(shù)組中
        Object[][] DataToOut = new Object[row][5];
        int readrow=0;
        while((line = in.readLine()) != null){
            String[] temp = line.split("\t");
            for(int j=0;j<temp.length;j++){
                DataToOut[readrow][j] = temp[j];
            }
            readrow++;
        }
        in.close();

        //顯示讀取出的數(shù)組
        for(int i=0;i<DataToOut.length;i++){
            for(int j=0;j<DataToOut[0].length;j++){
                System.out.print(DataToOut[i][j]+"\t");
            }
            System.out.println();
        }
        return DataToOut;
    }
}

前面的一段是將那個二維數(shù)組的數(shù)據(jù)寫入到指定的文本中磷脯。而后面的則是從文本中讀取出數(shù)據(jù)，并且解析為原先的二維數(shù)組娩脾。如果我們實(shí)際存在了一部分?jǐn)?shù)據(jù)赵誓，那么就可以直接將修改一下數(shù)組的大小并且改一下文件地址就好了。

正文之后

最近幾天忙活著籌謀一下畢業(yè)活動的策劃。然后就是爆肝畢業(yè)設(shè)計了俩功。感覺再不做完可能就要gg了隘冲，別到時候畢業(yè)失敗，那什么都是空的了绑雄！我的大好前程可就不在了！
