为什么要这么写
public class CDBean
{
private String cdName;
private String cdCompany;
private String cdAlbum;
private String cdType;
private long cdId;
public CDBean()
{

}

public void setCdName(String cdName)
{

this.cdName = cdName;
}

public String getCdName()
{

return cdName;
}

public void setCdCompany(String cdCompany)
{

this.cdCompany = cdCompany;
}

public String getCdCompany()
{

return cdCompany;
}

public void setCdAlbum(String cdAlbum)
{

this.cdAlbum = cdAlbum;
}

public String getCdAlbum()
{

return cdAlbum;
}

public void setCdType(String cdType)
{

this.cdType = cdType;
}

public String getCdType()
{

return cdType;
}

public void setCdId(long cdId)
{

this.cdId = cdId;
}

public long getCdId()
{

return cdId;
}
}
学java已经有段时间了，感觉java是层次感很强的,我主要学web方向的,象这样写是不是为了让各个层次不乱？

[解决办法]
同LS的。
应该是问为什么要有访问器吧？
变量的private不允许外部直接调用，这样写比较安全和规范
