如何在jdbc中进行实务操作呢？

package TX;

import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.SQLException;
import java.sql.Statement;

public class Transaction {
	public static void main(String[] args) {
		
		try {
			//加载驱动
			Class.forName("com.mysql.jdbc.Driver");
		} catch (ClassNotFoundException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}
		
		
		try
		(
			Connection c = DriverManager.getConnection(
					"jdbc:mysql://127.0.0.1:3306/Hero?characterEncoding=UTF-8",
					"root",
					"123");
			Statement s = c.createStatement();	
		)
		{
			//关闭自动提交功能  事务第一步骤
			c.setAutoCommit(false);
			
			//存1000块钱
			String sqlDeposit = "update money set balance=11000 where id =1"; 
			s.execute(sqlDeposit);
			
			
			//取1000块钱		如果这句出错的话就有效果了，上句执行的效果也没了，和没有执行一样的												
			String sqlWithDrow = "upate money set balance=8000 where id =1"; 
			s.execute(sqlWithDrow);
			
			//自己写个提交语句  事务第二步骤  中间的是逻辑语句
			c.commit();
			
			
			
			
			
			
			
			
			
		} catch (SQLException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}
	}
}
