CSV格式:

它可以用excel打开,如果用记事本打开,会发现它是一种使用逗号(",")作为不同列之间的分隔符.

读取CSV格式:

import java.io.*;

/**
 * 使用例子:
 * CSVReader reader = new CSVReader("D:\\114.csv");
 * String str1 = reader.readLine();//得到第一行
 * String str2 = reader.readLine();//得到第二行
 */
public class CSVReader {

    BufferedReader reader;

    public String readLine() throws IOException {
        return reader.readLine();
    }

    public CSVReader(String pathname) throws FileNotFoundException {
        this.reader = new BufferedReader(new FileReader(new File(pathname)));
    }

}

写入CSV格式:

import java.io.*;

/**
 * 使用例子
 * CSVWriter writer = new CSVWriter("D:\\114.csv");
 * writer.write(new String[]{"a", "b", "c"});//第一行写入 a b c
 * writer.write(new String[]{"d", "e", "f"});//第二行写入 d e f
 */
public class CSVWriter {

    private BufferedWriter writer;

    public void write(String[] writeStrings) throws IOException {
        for (String str : writeStrings) {
            writer.append(str + ",");
        }
        writer.append("\r");
        writer.flush();
    }

    public CSVWriter(String writePath) throws FileNotFoundException, UnsupportedEncodingException {
        this.writer = new BufferedWriter(new OutputStreamWriter(new FileOutputStream(new File(writePath)), "GBK"));
    }
}
