什麽是javabean,有什麽用啊

壹個javabean就相當於壹個數據模型,舉個例子,Student類就可以當做壹個數據模型類,也就是javabean,這個數據模型類壹般只包構造方法,屬性,以及這些屬性的set和get方法,下面我給妳壹個例子:

public?class?Student

{

private?String?name;

private?int?age;

private?int?hight;

/**

*?構造方法

*/

public?Student(String?name,?int?age,?int?hight)

{

this.name?=?name;

this.age?=?age;

this.hight?=?hight;

}

public?String?getName()

{

return?name;

}

public?void?setName(String?name)

{

this.name?=?name;

}

public?int?getAge()

{

return?age;

}

public?void?setAge(int?age)

{

this.age?=?age;

}

public?int?getHight()

{

return?hight;

}

public?void?setHight(int?hight)

{

this.hight?=?hight;

}

} 希望可以幫助到妳,有什麽疑問都可以追問,望采納,謝謝!
