问个问题，关于抽象类这么做有什么好处呢？新手求教

Java code

package po;// Generated by MyEclipse - Hibernate Tools/** * Toperator generated by MyEclipse - Hibernate Tools */public class Toperator extends AbstractToperator implements java.io.Serializable {    // Constructors    /** default constructor */    public Toperator() {    }        /** full constructor */    public Toperator(String operatorName, String operatorPwd, Long isAdmin) {        super(isAdmin, operatorName, operatorPwd, isAdmin);            }   }

------------------------

Java code

public abstract class AbstractToperator  implements java.io.Serializable {    // Fields         private Long operatorId;     private String operatorName;     private String operatorPwd;     private Long isAdmin;    // Constructors    /** default constructor */    public AbstractToperator() {    }    /** minimal constructor */    public AbstractToperator(Long operatorId) {        this.operatorId = operatorId;    }        /** full constructor */    public AbstractToperator(Long operatorId, String operatorName, String operatorPwd, Long isAdmin) {        this.operatorId = operatorId;        this.operatorName = operatorName;        this.operatorPwd = operatorPwd;        this.isAdmin = isAdmin;    }       // Property accessors    public Long getOperatorId() {        return this.operatorId;    }        public void setOperatorId(Long operatorId) {        this.operatorId = operatorId;    }    public String getOperatorName() {        return this.operatorName;    }        public void setOperatorName(String operatorName) {        this.operatorName = operatorName;    }    public String getOperatorPwd() {        return this.operatorPwd;    }        public void setOperatorPwd(String operatorPwd) {        this.operatorPwd = operatorPwd;    }    public Long getIsAdmin() {        return this.isAdmin;    }        public void setIsAdmin(Long isAdmin) {        this.isAdmin = isAdmin;    }   

[解决办法]
抽象类用的不太多的，主要也是就减少点代码量，体现在一个抽象类有多个子类的时候；个人感觉接口好用，建议楼主了解下面向接口编程的思想，之后你自己就明白优缺点了！

设计思想问题
我觉得工作一段时间就会体会到其中的好处了
