1，類的意思是什么

幾把

類的意思是什么

2，類是什么意思

　　類　　【字義】：很多相似事物的綜合：種類相似，好像：類同。

類是什么意思

3，有教無類中的類是什么意思

種類的意思~~~~~~~~（……）類別也就是不同的種類這是單純意思而這個詞中就是指不同的人類別的意思，指的是什么人都可以接受教育

有教無類中的類是什么意思

4，生產品類是什么意思

產品類型是指某一品牌產品類別，具體指把產品進行歸類。例如：我國汽車產品類別：我國汽車法規標準中大致有以下兩個分類標準: 1、汽車分為L類、M類、N類、O類汽車 L類指兩輪或三輪車(如摩托車等)；

5，編程里面的類和方法是什么意思

類是一個抽象的集合，抽象的意思是把一些事物的公共部分提取出來放在一個集合里面。在編程里類是指一組相同的屬性和功能的一個抽象集合，統稱為成員。方法是一個過程，方法也屬于類里面的一個成員（功能），方法是一個具體的執行過程，而類什么也做不了，它僅僅是一個概念，就好像人類什么也做不了，人才能做事情，做的事情的過程就是一個方法。

6，java里的類和對象分別是什么意思

marry是一個人 marry 就是一個具體的人而通常我們說人時，并不是說 marry 但是如果誰不知道什么是人，你可以告訴他，像marry那樣的就是人了所以：marry就是人這個類的一個具體的對象（也叫實例）要有marry（對象），首先得有人這個類（可以理解為類型），再 new 一個人才行，然后你可以把給這個 new 出來的人一個名字，比如marry。以后大家說到marry時，就是指的這個新人了，然而，marry始終是屬于人的類型。當然，你還可以說他是生物，或是女人，這就關系到繼承了

point point=new point(-1,-1); point.setx(0); point.sety(0); point.move(3); point.move(4); 能明白什么意思吧？簡略寫的 x和y要保證不是負數，x或y值為0時，再向邊界移動是否會出現異常
