Quick start

Once you clone this repo, these commands show how to compile and run the code inside. You need ant to following these instructions; refer to cs56-rational-ex02 and the article on ant for more information.

The build.xml file in this repo is set up to produce a jar file:

To run this new target, we use:

ex03 pconrad$ ant jar
Buildfile: /Users/pconrad/github/UCSB-CS56-M16/cs56-rational-example/ex03/build.xml

compile:
    [javac] Compiling 2 source files to /Users/pconrad/github/UCSB-CS56-M16/cs56-rational-example/ex03

jar:
      [jar] Building jar: /Users/pconrad/github/UCSB-CS56-M16/cs56-rational-example/ex03/build/rational.jar

BUILD SUCCESSFUL
Total time: 0 seconds
ex03 pconrad$ 

We can then run the file with this command:

ex03 pconrad$ java -jar build/rational.jar 
r.getNumerator()=5
r.getDenominator()=7
ex03 pconrad$ 

To compile:

ex03 pconrad$ ant compile
Buildfile: /Users/pconrad/github/UCSB-CS56-M16/cs56-rational-example/ex03/build.xml

compile:
    [javac] Compiling 3 source files to /Users/pconrad/github/UCSB-CS56-M16/cs56-rational-example/ex03

BUILD SUCCESSFUL
Total time: 0 seconds
ex03 pconrad$ 

To run the JUnit tests in the repo:

ex03 pconrad$ ant test
Buildfile: /Users/pconrad/github/UCSB-CS56-M16/cs56-rational-example/ex03/build.xml

compile:
