这是我一直用来从CSV文件中读取所有记录的代码。 我对Java很陌生。

FileReader openFile = new FileReader("/Users/ABC/Desktop/Test/myFirstFile.csv"); 

    BufferedReader readMyDataObj = new BufferedReader(openFile)
    FileWriter writer2 = new FileWriter("/Users/ABC/Desktop/Test/mySecondFile.csv");
    BufferedWriter bf2 = new BufferedWriter(writer2);
    String data2;
    while ((data2=readMyDataObj.readLine())!=null) {    
    bf2.write(data2);
    bf2.newLine();       
     }
    bf2.close();                   
    writer2.close();
    openFile.close();
