如何创建移动应用程序? [英] How to create mobile Application?

问题描述

任何人都知道如何使用Netbean IDA 6.9.1创建移动应用程序
我正在使用诺基亚E50，我希望为其开发一个Java应用程序来发送加密消息，因为它是我的项目的一部分.

在我的项目中很好，我正在使用移动SMS在数据库上执行一些DBA(数据库管理员)操作，因为该项目基本上是供DBA使用的，它维护数据库并对其具有完全访问权限.

如果是数据库，主要问题将是这种访问应该是安全的，因此我想实现某种加密技术.
j2me应用程序中可以加密吗?
我还有另一种选择，可以在应用程序中为特定的15-20任务设置一些按钮，而只需为其指定参数即可.
告诉我哪种方式比较方便?

我不知道如何在Netbeans中开发应用程序
我有Netbeans IDA 6.9.1
如果有人有小的代码可以告诉我如何创建移动Java应用程序
如果有人的话，请给我发送邮件或在此处附加

那就是为什么我发布我的算法来询问它对这样的项目有用吗?





这是我要在此应用程序中实现的小型算法.

步骤1:生成字母的ASCII值.

步骤2:生成相应的二进制值.
[二进制值应为8位数字，例如十进制的32个二进制数应为00100000]

步骤3:将8位数的二进制数字取反.

步骤4:以4位数的除数(> = 1000)为键.

步骤5:将除数除以除数.

第6步:将余数存储在接下来的5位的前3位商中(余数和商的长度分别不超过3位和5位.如果其中任何一个分别少于3位和5位，我们需要添加左侧的0(零)个数.因此，这将是密文，即加密的文本.
现在，将余数存储在下一个5的前3位商中
数字.

步骤7:通过用户签名附加SMS.

有可能吗?

Hi,
anybody knows how to create mobile application using Netbean IDA 6.9.1
I am using nokia E50 for which I want make one java application for sending encrypted message as it is part of my project.

well in my project I am using mobile SMS to perform some DBA(DataBase Administrator) operation on database because this project is basically for DBA use, which maintain database and have full access on it.

In case of database the main issue will be this access should be secure so I want to implement some encryption technique.
Is it possible to encryption in j2me application?
I have another option to make some buttons in my application to specific 15-20 task and just specify the parameter to it.
Tell me which way will be convenient ?

As I don''t know how to develop application in Netbeans
I have Netbeans IDA 6.9.1
If anybody have small code which will tell me how to create mobile java application
if anyone having small ppt of it then please send me or attach here

thats why I posted my algorithm to ask can it usefull to such project?





Here is small algorithm which I want to implement in this application.

Step 1: Generate the ASCII value of the letter.

Step 2: Generate the corresponding binary value of it.
[Binary value should be 8 digits e.g. for decimal 32 binary number should be 00100000]

Step 3: Reverse the 8 digit’s binary number.

Step 4: Take a 4 digit divisor (>=1000) as a key.

Step 5: Divide the reversed number with the divisor.

Step 6: Store the remainder in first 3 digits quotient in next 5 digits (remainder and quotient wouldn’t be more than 3 digits and 5 digits long respectively. If any of these are less than 3 and 5 digits respectively we need to add required number of 0s (zeros) in the left hand side. So, this would be the cipher text i.e. encrypted text.
Now store the remainder in first 3 digits quotient in next 5
digits.

Step 7: SMS is appended by user signature.

Is it possible to do?

推荐答案

以下是一个线索:以

Here is a clue: start with this[^] and when you have an actual programming problem come back and post your question.

此外，Richard的答案是，如果将问题分解为不同的部分，将变得非常容易.

0.输入字符串.
1.加密.
2.发送短信.

这三个步骤均已完成，因此您的问题就变成了将它们粘合在一起的情况.

Additionally to Richard''s answer, if you split the problem into it''s distinct parts it becomes really easy.

0. Entry of a string.
1. Encryption.
2. Sending an SMS.

All three have been done before and so your problem becomes a case of glueing it all together.
