Java 把文本中的数据插入到MySql数据库

一共有三个类：WriteFile ; ReadFile ; InsertDB ;
//WriteFile.java
//用于将信息写入文本文件
package org.mb.insertfromfile;
import java.io.*;
public class WriteFile{
private int count = 0 ;
public int getCount() {
return count;
}
public void setCount(int count) {
this.count = count;
}

public void write() throws Exception{

File f = new File("f:\\stu1.dat");
f.createNewFile();
FileOutputStream fos = new FileOutputStream(f);
DataOutputStream dos = new DataOutputStream(fos);

this.count++;
dos.writeUTF("洪吉童");
dos.writeInt(80);
dos.writeInt(75);
dos.writeInt(65);
dos.writeInt(50);

this.count++;
dos.writeUTF("徐光豪");
dos.writeInt(90);
dos.writeInt(100);
dos.writeInt(100);
dos.writeInt(100);

this.count++;
dos.writeUTF("林顺喜");
dos.writeInt(60);
dos.writeInt(70);
dos.writeInt(55);
dos.writeInt(75);

this.count++;
dos.writeUTF("李之梅");
dos.writeInt(60);
dos.writeInt(80);
dos.writeInt(75);
dos.writeInt(80);

this.count++;
dos.writeUTF("洪顺熙");
dos.writeInt(80);
dos.writeInt(70);

dos.writeInt(85);

this.count++;
dos.writeUTF("朴顺吉");
dos.writeInt(100);
dos.writeInt(80);
dos.writeInt(90);
dos.writeInt(85);


dos.flush();
dos.close();
}
} 
//ReadFile.java
//用于返回文本中的信息
package org.mb.insertfromfile;
import java.io.*;
public class ReadFile {
public String[] read()throws Exception{

for (int i=0 ; i<str.length ; i++){
