算法第四版 在Linux 中调用Algs4库

一: 搭建Java 环境   :

 确认版本: 1.8及以上

[username:~/] javac -version
javac 1.8.0_111

[username:~/] java -version
java version "1.8.0_111"
Java(TM) SE Runtime Environment (build 1.8.0_111-b14)
Java HotSpot(TM) 64-Bit Server VM (build 25.111-b14, mixed mode)

二  

• 建立目录 /usr/local/algs4.

  [username:~/] cd /usr/local
  [username:/usr/local] sudo mkdir algs4
  [username:/usr/local] sudo chmod 755 algs4
  

  进入子目录 /usr/local/algs4.

  [username:/usr/local] cd algs4
  [username:/usr/local/algs4] pwd
  /usr/local/algs4

• 下载 algs4.jar (包括了javac-algs4 和java-algs4).

  [username:/usr/local/algs4] sudo wget http://algs4.cs.princeton.edu/code/algs4.jar
  [username:/usr/local/algs4] sudo wget http://algs4.cs.princeton.edu/linux/javac-algs4
  [username:/usr/local/algs4] sudo wget http://algs4.cs.princeton.edu/linux/java-algs4
  [username:/usr/local/algs4] sudo chmod 755 javac-algs4 java-algs4
  [username:/usr/local/algs4] sudo mv javac-algs4 /usr/local/bin
  [username:/usr/local/algs4] sudo mv java-algs4 /usr/local/bin

• 检查是否安装成功
  

  machine:~/hello username$ java-algs4 edu.princeton.cs.algs4.StdDraw
  [ displays a graphics window with some geometric shapes and text ]
  
  machine:~/hello username$ java-algs4 edu.princeton.cs.algs4.StdAudio
  [ plays an A major scale ]
