1.哪位大哥能给我一个基于IDEA算法的导航地图源码c或者c++的软件以及源代码啊
2.java代码在哪里编写？
3.学习JAVA要安装什么软件？
4.idea格式化代码设置(idea的格式化)
5.工作三年还不懂facet？赶紧学一学IntelliJ IDEA如何管理java项目
6.Intellij IDEA如何创建Maven项目

       // Project: Implementation of IDEA (International

       // Data Encryption Algorithm)

       //

       // ECE Term Project

       // Winter

       // Author: Irwin Yoon

       //

       // Overview: This code does the following:

       // - print out all encryption and

       // decryption subkeys which are used

       // in the encryption and decryption

       // process

       // - encrypts plaintext message

       // - decrypts ciphertext message

       // - shows detailed, round by round results

       // (8 total)

       // Program contains a user driven menu where the user can select

       // initial -bit key and also select messages to decrypt

       // and encrypt.

       //

       // Compiling: This has been verified to work on SunOS

       // with g++ compiler (flop.engr.orst.edu).

       // To Compile: g++ Idea.cpp -o Idea.exe

       //

       // Note: This code is a little sloppy. Coding could

       // be made more efficient.

       //

       // Usage: Run executable with no arguments: Idea.exe

       // Then select appropriate menu options

       //

       //
