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(wú)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(gè)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(wú)類中的類是什么意思

4，生產(chǎn)品類是什么意思

產(chǎn)品類型是指某一品牌產(chǎn)品類別，具體指把產(chǎn)品進(jìn)行歸類。例如：我國(guó)汽車產(chǎn)品類別：我國(guó)汽車法規(guī)標(biāo)準(zhǔn)中大致有以下兩個(gè)分類標(biāo)準(zhǔn): 1、汽車分為L(zhǎng)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(gè)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(lái)放在一個(gè)集合里面。在編程里類是指一組相同的屬性和功能的一個(gè)抽象集合，統(tǒng)稱為成員。方法是一個(gè)過程，方法也屬于類里面的一個(gè)成員（功能），方法是一個(gè)具體的執(zhí)行過程，而類什么也做不了，它僅僅是一個(gè)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(gè)方法。

6，java里的類和對(duì)象分別是什么意思

marry是一個(gè)人 marry 就是一個(gè)具體的人而通常我們說人時(shí)，并不是說 marry 但是如果誰(shuí)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(gè)類的一個(gè)具體的對(duì)象（也叫實(shí)例）要有marry（對(duì)象），首先得有人這個(gè)類（可以理解為類型），再 new 一個(gè)人才行，然后你可以把給這個(gè) new 出來(lái)的人一個(gè)名字，比如marry。以后大家說到marry時(shí)，就是指的這個(gè)新人了，然而，marry始終是屬于人的類型。當(dāng)然，你還可以說他是生物，或是女人，這就關(guān)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(jiǎn)略寫的 x和y要保證不是負(fù)數(shù)，x或y值為0時(shí)，再向邊界移動(dòng)是否會(huì)出現(xiàn)異常
