在Java中使用RandomAccessFile寫入和讀取文件

您好，我正在編寫一個在Java中寫入和讀取文件XML的程序。這是寫入文件

public static void main(String[] args) throws IOException {
    File file = new File("C:\\Test\\employee.XML");
    RandomAccessFile randomAccessFile = new RandomAccessFile(file, "rw");
    //int codeEmp = 0;
    String nameEmp[] = {"Name A", "Name B", "Name C", "Name D", "Name E"};
    String addEmp[] = {"Address A", "Address B",
            "Address C", " Address D",
            "Address E"};
    int saleEmp[] = {2000,1232,7653,1236,3452};
    int comEmp[] = {400,100,3000,300,500};

    StringBuffer buffer;
    StringBuffer buffer1;


    for (int i=0;i< nameEmp.length; i++){
        randomAccessFile.writeInt(i+1);

        buffer = new StringBuffer( nameEmp[i]);
        buffer.setLength(10);
        randomAccessFile.writeChars(buffer.toString());

        buffer1 = new StringBuffer( addEmp[i]);
        buffer1.setLength(100);
        randomAccessFile.writeChars(buffer1.toString());


        randomAccessFile.writeInt(saleEmp[i]);
        randomAccessFile.writeInt(comEmp[i]);
    }
    randomAccessFile.close();
}

讀者是

public static void main(String[] args) throws IOException {
    File file = new File("C:\\Test\\employee.XML");
    RandomAccessFile randomAccessFile = new RandomAccessFile(file, "rw");

    int codeEmp, position = 0;
    char nameEmp[] = new char[10];
    char addEmp[] = new char [100];
    int saleEmp , comEmp;

    for(;;){
        randomAccessFile.seek(position);
        codeEmp = randomAccessFile.readInt();

        for (int i = 0; i < nameEmp.length; i++) {
            nameEmp[i] = randomAccessFile.readChar();
        }
        String nameEmpS= new String(nameEmp);

        for (int i = 0; i < addEmp.length; i++) {
            addEmp[i] = randomAccessFile.readChar();
        }
        String addEmpS= new String(addEmp);

        saleEmp =randomAccessFile.readInt();
        comEmp=randomAccessFile.readInt();

        System.out.println("Cod Emp: " + codeEmp + ", nombre: " +nameEmpS+ ", dirección: "+addEmpS+
                ", sale: " + saleEmp+ ", comisión: " + comEmp );

        position= position + 36;

        if (randomAccessFile.getFilePointer()==file.length())break;
    }
    randomAccessFile.close();
}

問題是，當(dāng)我運(yùn)行閱讀器文件時，它返回了許多行，只有第一行是可以的，但其他行是錯誤的。我怎樣才能修復(fù)它？這是控制臺
