java的实训心得与体会篇一
本次我们小组所做的程序是“小小通讯录”基本功能已经较好的完成,可是还是有一些不完善,比如我们的通讯录没有能够做到把通讯录里所储存的信息以列表的形式展现出来,所以还是有些不完善,,我们的指导老师对我们的程序作出了大体评价,发现我们的思想还是处于一个比较简单的过程当中,老师的几句简单评价,就带给我们无与伦比的冲击性,由于我们写程序的经验尚且较少,很多东西无法考虑到位,老师的点评,使我们认识到了不足与今后的前进方向与目标,使我们更加具有动力与激情,拥有了继续认真学习java的信心,拥有了成为一位合格的高级程序员的壮志,在编写程序的过程当中,我们在一开始就遇到了问题,一直在纠结与是使用数据库连接还是使用文件,经过老师的耐心讲解,我们了解到了尚未接触到的jar包等一些列名词,但是经过数据库的抒写与连接发现sql20xx与sql20xx无法同步,所以最终我们选择了使用文件来进行这次程序的编写,第二个问题就是我们的程序在进行按钮新窗口的链接,在新窗口弹出时,无法将老窗口关闭,纠结了好久,询问老师,老师还给我用了“父子”的生动例子来讲解,最终我们查找jdk,查找类的用法终于完美解决!甚是兴奋! 在我所学的语言当中,我自认为java是一门比较强大的面向对象的编程语言,不仅仅因为它的跨平台性,更多的是因为它的灵活多变和实用性较强,可以说比较的经典和强悍。
所以学好java语言有很大的用处,这次实训,面对一道陌生的题目和要求时,不应慌张和无措,首先应该想到这和课本上的哪些知识具有结合点,回忆和分析这种结构的算法和具体实施方法,综合考虑其他的方面,例如:该题的易写性和易懂性及其他的问题的可利用性。在编写时,一个小小的符号,一个常量变量的设定,这都无不考量着我们的细心和严谨,所以学习java,不仅对我们以后学习其他语言有很大的好处,而且也让我们知道了和理解了作为一个编程人员首先应具有的良好心理素质,那就是冷静思考和专心致志。对待学术知识应该是严谨和认真。
这次实训,我们更多学到的是不懂就问和自己应该尽自己的全力去尝试,哪怕失败,只要自己尽自己的全力,和身边同学一起探讨而不是抄袭,团结合作,发挥团队意识,最后在自己的努力下,终于运行成功,这种成就感美不可言,心情愉悦至极。
据我了解,软件工程专业培养的工程型人才要富有创新精神。软件工程技术人员致力于开发可靠好用的计算机产品和软件产品,必须具有扎实宽泛的知识面和较高的社会责任感,必须了解最新的技术进展、能够综合运用各方面技术并深刻理解设计一个合格产品所涉及的多方面因素,如市场需求、用户习惯等。另外,
这两个学科领域是相辅相成的,并共同推进计算机技术的方展。计算机技术的发展会推动软件的开发,软件工业则对计算机科学技术的进展以及软件应用领域的扩展起着重要的推动作用。软件工程人才的就业前景十分看好。
未来几年,国内外高层次软件人才将供不应求。毕业生主要在各大软件公司、企事业单位、高等院校、各大研究所、国防等重要部门从事软件设计、开发、应用与研究工作。有数据表明,我国软件出口规模达到215亿元,软件从业人员达到72万人,在中国十大it职场人气职位中,软件工程师位列第一位,软件工程人才的就业前景十分乐观。信息化是it界的焦点。而信息化的实现,除了需要技术支持,人才也是很重要的环节。如何培养与国际接轨的高素质软件工程人才,已经成为中国软件产业的当务之急。
软件产业的发展水平,决定了一个国家的信息产业发展水平及其在国际市场上的综合竞争力。目前,我国软件高级人才的短缺已经成为制约我国软件产业快速发展的一个瓶颈。在中国,国内市场对软件人才的需求每年高达20万人,而高校计算机毕业生中的软件工程人才还很缺乏,尤其是高素质的软件工程人才的极度短缺。尽快培养起适合信息产业所需要的高素质软件工程人才,已经成为信息化工作中的重中之重。java具有如此好的就业与发展前景,使我更加坚定了软件开发这条道路。但是自己还与很多不足,需要努力学习与改进,关键是读这个专业要自己动手实践,自己解决实践中发生的问题,对任何程序要懂得举一反
三。如果指望按书本的步骤做..指望每学期死记硬背通过考试..那绝对是没前途了..如果一个软件工程的学生都是在玩电脑游戏中度过每个学期的..那就不要期望毕业能找到本专业的好工作了.... sun公司副总裁、sun研究院院士、软件部首席技术官詹姆斯?戈士林(jamesgosling)博士以"java技术之父"闻名于世。作为sun研究院院士,他亲手设计了java语言,完成了java技术的原始编译器和虚拟机。在他的带领下,java现已成为互联网的标准编程模式以及分布式企业级应用的事实标准,其跨平台的技术优势为网络计算带来了划时代的变革。自1995年5月正式推出的11年以来,java已从编程语言发展成为全球第一大通用开发平台。java技术已为计算机行业主要公司所采纳,同时也被越来越多的国际技术标准化组织所接受。1999年,sun推出了以java2平台为核心的j2ee、j2se和j2me三大平台。随着三大平台的迅速推进,在世界上形成了一股巨大的java应用浪潮。作为唯一在互联网上开发的语言,java平台以其移动性、安全性和开放性受到追捧。 目前,中国的软件人才主要有两方面的欠缺,一是英语水平差,二是软件开发经验缺乏。针对这种情况,很多软件学院大幅增加了英语课时,同时广泛采用国外原版教材,部分基础课和专业课采用双语教学甚至全英文授课。各软件学院还特别强调实践环节。像清华软件学院90%的专业课程都配有课程实验大作业,学生从本科二年级起就能根据兴趣选择参加各种研究所的研究工作。所以我还要努力学习英语,提高自己各方面技能java如此潮流,我就更具信心,争取早如成为一名合格的专业性人才!
最后终于要结束了,大家都有种释怀的感觉,当然我想我更多的是兴奋和自己掌握了知识之后的饱满感,学知识就像吃东西一样,吃饱了就应该好好的消化。要不断的温习和运用,做到举一反三,将所学知识充分融入到平时的学习生活中
去,为以后的工作做好坚实的基础。感谢学校和老师能够为我们提供这次机会,让我们更好的掌握和了解java这门语言。谢谢!
java的实训心得与体会篇二
通过这一期的实习,虽然实习的时间不长,但是总体上收获挺大的,学习中我不但有了学习成果的喜悦,而且自己也日渐成熟,有种说不出的喜悦。
当我们正式准备学习实习java编程技术时,让我倍感兴奋,毕竟java是自己以后想主攻技术,所以自然也就非常的亢奋。刚开始实习的第一天,同学们就推荐我为组长,我感觉肩上责任之重大,那一刻起,我就决心带领我们小组,奋战我们的实习路。当然开始学习后也并非是想象中那样顺利,开始的学习让我异常感到学习任务的艰巨,因为学习中我们遇到了很多以前未曾遇到的难点,有时难免冥思苦想也无济于事,通过我们小组的积极努力协作,同时请教老师和其他同学,我们顺利的化解了一道道的障碍。
这让我不断的对学习技术又有了新的认识:学习中我们必须边总结边学习,开始阶段对老师交代的任何方法和类都不要放过,不管是否简单与否都要乐于地接受,因为老师肯定有他的道理,相信老师走过的路比我们长,那么其经验也就肯定比我们丰富。上课时一定要专心听讲,一个关键的知识点听漏了,可能会使一个人在课下花很多时间去消化,这样也就会花掉做其他事情的大量时间,同时也使得学习不能和老师的讲的课程同步,以至出现以后就跟不上老师讲课的进度而掉队。所以学习中我们宁可先劳其筋骨,苦其心志,恶其体肤,也不能掉队跟不上学习进度。
在这里,我非常感谢实习的指导老师,在老师的帮助和指导下,我克服了java学习上的一道道难关,课上认真听讲,摘好必要的笔记,并通过自己课后的不断消化学习,现在自己已经基本掌握了java的基础知识,并且能独立的开发出系统。
实习即将结束了,我非常怀念厦门万策在南昌大学的校内实习,在实习的这短短两周的时间里,我每一天过的都市踏实的,充实的;我相信,只要我秉持艰苦奋斗,为理想拼搏的精神,尽管在未来的java路上荆棘丛丛,我一定可以披荆斩刺,度过重重难关,实现自己未来的理想!
实习是为将来打基础的重要阶段,珍惜自己每一个工作的机会,不论什么人,什么学历,从事什么工作,好好的表现、展示自己的能力,不要错过好的机遇。没有一件事情是轻轻松松的,但每一件事都是让人成长的,经历一段过程,喜悦或是艰辛,尽管经历的方式不尽相同,但它的结果是相同的,我们都会因涉事而成长。
通过实习,我自身发生了重大的转变。首先,进入公司,你就是一名职业人,不再是一名学生,你要具备一名职业人应具备的素养,不迟到不早退是必然的,而且还要时刻严格要求自己,公司的规定要严格遵守。然后,在技术上也有了很大的提高,学习了很多公司自己的框架和工具,这都是一些前辈的宝贵经验。而且所作的软件应用性更强。所以,我要坚定自己的信念,在公司好好实习,争取提早转正,我相信我会在java开发这条路上走的更长更远。
有些知识点以前没有学过,但我也没有去研究,实习时突然间觉得自己真的有点无知,虽然现在去看依然可以解决问题,但要浪费许多时间,这一点是我必须在以后的学习中加以改进的地方,同时也要督促自己在学习的过程中不断的完善自我。 另外一点,也是在实习中必不可少的部分,就是同学之间的互相帮助。所谓”当局者迷,旁观者清”,有些东西感觉自己做的是时候明明没什么错误,偏偏程序运行时就是有错误,让其他同学帮忙看了一下,发现其实是个很小的错误。所以说,相互帮助是很重要的一点,这在以后的工作或生活中也是很关键的。 俗话说:“要想为事业多添一把火,自己就得多添一捆材”。 此次实习,我深深体会到了积累知识的重要性。在实习当中我们遇到了不少难题,但是经过我们大家的讨论和老师细心的一一指导,问题得到了解决。 两个礼拜的实习结束了,收获颇丰,同时也更深刻的认识到要做一个合格的程序员并非我以前想像的那么容易,最重要的还是细致严谨。社会是不会要一个一无是处的人的,所以我们要更多更快地从一个学生向工作者转变,总的来说我对这次实习还是比较满意的,它使我学到了很多东西,为我以后的学习做了引导,点明了方向,我相信在不远的未来定会有属于我们自己的一片美好天空!
java的实训心得与体会篇三
作为就业培训,项目的好坏对培训质量的影响十分大,常常是决定性的作用。这篇文章是关于在学习java软件开发时练习项目的总结,简单总结为以下几点:
1、项目一定要全新的项目,不能是以前做过的
2、项目一定要企业真实项目,不能是精简以后的,不能脱离实际应用系统copyright dumeiwen
3、在开发时要和企业的开发保持一致
4、在做项目的时候不应该有参考代码
长话短说就是以上几点,如果你想要更多的了解,可以继续往后看。
因为参加就业培训的学员很多都是有一定的计算机基础,大部分都具备一定的编程基础,尤其是在校或者是刚毕业的学生,多少都有一些基础。
他们欠缺的主要是两点:
(1)不能全面系统的、深入的掌握某种技术,也就是会的挺多,但都是皮毛,不能满足就业的需要。
(2)没有任何实际的开发经验,完全是想象中学习,考试还行,一到实际开发和应用就歇菜了。
解决的方法就是通过项目练习,对所学知识进行深化,然后通过项目来获取实际开发的经验,从而弥补这些不足,尽快达到企业的实际要求。
项目既然那么重要,肯定不能随随便便找项目,那么究竟如何来选择呢?根据java的研究和实践经验总结,选择项目的时候要注意以下方面:
1:项目不能太大,也不能太小
这个要根据项目练习的阶段,练习的时间,练习的目标来判断。不能太大,太大了做不完,也不能太小,太小了没有意义,达不到练习的目的。
2:项目不能脱离实际应用系统
项目应该是实际的系统,或者是实际系统的简化和抽象,不能够是没有实战意义的教学性或者是纯练习性的项目。因为培训的时间有限,必须让学员尽快地融入到实际项目的开发当中去。任何人接受和掌握一个东西都需要时间去适应,需要重复几次才能够真正掌握,所以每个项目都必须跟实际应用挂钩。
3:项目应能覆盖所学的主要知识点
学以致用,学完的知识点需要到应用中使用,才能够真正理解和掌握,再说了,软件开发是一个动手能力要求很高的行业,什么算会了,那就是能够做出来,写出代码来,把问题解决了,你就算会了。读美文
4:最后综合项目一定要是实际应用系统
学员经过这个项目的练习,就要走上实际的工作岗位了,如果这个系统还达不到实际应用系统的标准,学员练习过后也还是达不到企业实际的需要,那么这个培训应该说质量就不高了。理想的状况是这个项目就是实际项目,到时候学员就业到另外一个公司,不过是换个地方干活而已,完全没有技能上的问题。
这个不是靠想象,而是根据实际的情况一步一步分析出来的(呵呵要卖弄一下:这也算是逻辑思维),当然这里只是讨论方法,不涉及具体的项目案例。
我们可以采用倒推的方式来分析:
(1)最终的项目一定是真实的项目,也就是要把学员训练到能够独立开发实际应用,通常我们还不能选最简单的项目,因为学员的吸收还要有一个折扣,所以最终的项目应该选实际项目中中等难度的项目
(2)最终项目定下来过后,开始分解这个项目,看看为了达到完成这个项目需要哪些技术和知识点,以及每部分知识点的深度,然后定出每个分阶段的任务
(3)然后开始选择分阶段的项目,分阶段的项目应该比刚才分析出来的分阶段任务稍稍复杂点,这样才能达到训练的.目标。定下分阶段项目后,同样去分解,定出为了完成他所需要的各部分知识点和深度。
(4)然后是选择上课期间的演示项目,演示的项目是为了做分阶段项目服务的,可以认为是分阶段项目的分阶段项目
(5)最终把要求掌握的知识点和要求掌握的深度,分散到日常教学和练习中。好了,把上面的分析用正向描述就是:
日常教学和练习中学习和掌握的知识==〉演示项目==〉分阶段项目==〉综合项目==〉胜任企业实际开发需要。
附注:有了好的项目还要有好的训练方法(这个另外立文讨论),最最基本和重要的一条就是:绝对要指导学生亲自动手做,而不是看和听,所以尽量不要选择有现成代码的项目,演示用的项目也最好不配发代码,让学生能够跟着做出来才是真的掌握了。
上面阐述了java对项目的态度和基本选择方法,这里再把其中几个重要的、与众不同的特点阐述如下:
1:真项目
项目一定要真实,要是企业实际应用的,不能是教学性的项目,否则会脱离实达不到项目实训的效果。还有一个一定要是最新的项目,企业的要求也是在不断变化的,应用技术的方向和层次也在不断变化,这些都体现在最新项目的要求上,旧项目所要求的技术和层次很可能已经过时了,根本达不到训练的目的。
java的做法是:没有固定项目,每个班做项目之前会从企业获取最新的项目需求,然后经过挑选和精心设计,以保证既能训练技术,又能得到实际的开发经验。这样实现了跟企业的同步,企业做什么,我们就学什么,然后也跟着做什么。
2:真流程
开发的流程也要跟企业的实际开发保持一致。从项目立项开始,到需求分析、概要设计、详细设计、编码、测试的各个环节,都要完全按照真实的开发流程来做。
java的主力老师都是实战出身,在java开发方面都至少有七年以上的开发经验,同时具备多年的项目管理经验,所以能够完全按照企业开发的流程来训练学生。
3:真环境
开发的环境也要跟企业一样,包括常用的开发工具、开发平台、应用服务器、常用插件、测试工具、项目管理工具、项目管理文档等等。
java的做法是:构建跟企业完全一样的环境,然后跟企业开发一样,分团队开发。老师就相当于项目经理,一个班分成多个小组,每个组有自己的team leader,大家分工合作,共同完成项目。
4:真开发这是java最与众不同的一点,java深知:软件是做出来的,而不是听出来或者看出来的,企业需要能实际开发的人员,而不是只听过、看过但不能做的人。所以java十分强调:项目一定要让学生动手写出来。
java的做法是:老师做为项目经理,带领着大家一起去做需求分析、概要设计、数据结构设计、接口设计、重要业务流程的分析设计等,然后由学生们分团队进行开发,实现整个项目。这里有几个与众不同:
现场带领学生一起做分析和设计,而不是预先做好了来讲讲。因为需要学生学习的是分析设计的过程和方法,而不是已经做好的结果。
java的实训心得与体会篇四
大四初始,我已经闻到了离别的气息,在这即将远离大学时代的时刻,才真正懂得回眸的意义。想想走过的路,想想现在的路,想想来时的路,不知道未来能否成功,既然选择了远方,就注定要风雨兼程!
在四川短暂的一个月里,我从基础入手,强化了java语言编程,学习了java语言编程和编程概念与技巧。时间很短,但成长很快,无论是理论知识还是动手实践能力都得到了大幅度的提高。而将理论和实践相结合,相互促进,相互补充,使得学习更加透彻。通过用不同方法实现同一个项目,不断深入,层层推进,学以致用!
实践过程中,开发一个简单的小项目,包括如何将java的思想运用到实际系统的详细设计之中。 首先要将系统要实现的功能分为几大模块,然后每个分别完成,在此过程中使我加深了对java的理解,以及如何进行工作的划分,与此同时熟练掌握java语言的编辑,编译,调试程序,并将算法转变为程序实现。 我将设计过程分为逻辑设计和详细设计两个步骤实现。逻辑设计指的是,对问题描述中涉及的对象定义相应的数据类型,定义主程序模块和各抽象数据类型及其代码;详细设计则为定义相应的模块的实现并写出各模块的实现代码。然后在连接数据库,编码测试,最后确定完成。
通过这次实践,使我灵活应用所学知识,独立完成问题分析,结合java理论知识,编写程序解决指定问题。初步掌握软件开发过程的问题分析、系统设计、程序编码、测试等基本方法和技能;提高综合运用所学的理论知识和方法独立分析和解决问题的能力。同时在这次实践中,培养了独立思考、动手操作的能力,在各种其它能力上也都有了提高。 然而,在这次实践中,我觉得一个人完成一个项目是多么的艰难,在一些大型的项目中,团队合作是多么重要。尽管这次只是一个小项目,却也要耗费大量的精力。 我学习了知识,也培养了实践能力,让我知道遇到一个问题,如何去寻找思路,如何去解决问题,最终完成整个事情。 学习的过程中不可避免的遇到问题,这些问题有的只是一个符号错了,一个括号少了,这类的问题在他的文档,或者一般的网站上就能够找到,尤其是初学者的问题,不会是很难的问题 ,在你之前已经无数人问过了,不要害怕提问,但
是这个问题最好是你找不到答案的时候去提。等你走出了这个阶段,这个时候在有问题可能就是比较难一些的,这个时候在一般的网站上应该是难以找到结果的,包括java自己的网站,为你养成良好的习惯有很大的帮助。
这次实习拉近了我与社会的距离,也让自己在实习工作中开拓了视野,增长了才干。社会和大学一样也是一个学习和受教育的地方,但无论是在哪片广阔的天地里,我为将来更加激烈的竞争打下了更为坚实的基础。在以后的学习中,我还得更加努力的学习,培养自己的能力,进一步完善自己。
编程是一种乐趣,只有你觉得他有乐趣的时候你才会用更多的热情去学习。通过一个月的java学习,我也从中找到了乐趣。接下来,我一定会坚持java的学习,希望能在这条道路上开心的走下去,而最重要的是及时总结昨天、做好今天、规划好明天。
java的实训心得与体会篇五
在本学期的最后一周,我们在学校机房进行了为期一周的java实训。现在即将结束了,回首本学期的java学习,重点还是在学习概念等一些常识性的东西,application应用程序和applet小程序,它的开发工具,数据类型,变量,接口,输入输出流,学会分析异常,抛出异常,后期主要是小程序运用,gui界面设计和事件。我觉得这两种程序结构有很大的不同,不管是体系结构还是运行方式,都有很大的区别,我主要偏向于小程序的学习,呵呵,因为感觉它用处比较大,可以做出好多好多好玩的游戏,运用程序等,且它灵活。呵呵,当然学知识可不能凭自己的爱好和一时兴趣,要一步一个脚印,认认真真,踏踏实实,理论与实践相结合,在扎实掌握课本实例和内容之后,有一定的扩展阅读和课外学习,充分全面的了解java的应用和扩展运用。
在我所学的语言当中,我自认为java是一门比较强大的面向对象的编程语言,不仅仅因为它的跨平台性,更多的是因为它的灵活多变和实用性较强,可以说比较的经典和强悍。
所以学好java语言有很大的用处,这次实训,面对一道陌生的题目和要求时,不应慌张和无措,首先应该想到这和课本上的哪些知识具有结合点,回忆和分析这种结构的算法和具体实施方法,综合考虑其他的方面,例如:该题的易写性和易懂性及其他的问题的可利用性。在编写时,一个小小的符号,一个常量变量的设定,这都无不考量着
我们的细心和严谨,所以学习java,不仅对我们以后学习其他语言有很大的好处,而且也让我们知道了和理解了作为一个编程人员首先应具有的良好心理素质,那就是冷静思考和专心致志。对待学术知识应该是严谨和认真。
这次实训,我们更多学到的是不懂就问和自己应该尽自己的全力去尝试,哪怕失败,只要自己尽自己的全力,和身边同学一起探讨而不是抄袭,团结合作,发挥团队意识,最后在自己的努力下,终于运行成功,这种成就感美不可言,心情愉悦至极。
最后终于要结束了,大家都有种释怀的感觉,当然我想我更多的是兴奋和自己掌握了知识之后的饱满感,学知识就像吃东西一样,吃饱了就应该好好的消化。要不断的温习和运用,做到举一反三,将所学知识充分融入到平时的学习生活中去,为以后的工作做好坚实的基础。感谢学校和老师能够为我们提供这次机会,让我们更好的掌握和了解java这门语言。谢谢!
