使用遗传算法进行的自动排课设计，需要指出算法具体对应的代码中

需要指出遗传算法对应步骤是用哪些代码实现的，大家帮帮忙，谢谢谢谢！

java代码如下：

package com.autosortcourse.beans;

import com.autosortcourse.database.PersistenceManager;

//import java.sql.Connection;
import java.sql.ResultSet;
import java.sql.SQLException;
//import java.sql.Statement;

//import java.lang.*;
import java.util.Random;
import com.autosortcourse.beans.CInfoImpl;
//import com.autosortcourse.beans.SelectCmd;
import com.autosortcourse.bean.CInfoBean;
