,TOPIC 1: UNIX
Development tools:
- When you don't have an IDE, you need to use development tools such as:

1. Text editor
2. Compilers
3. Makefile and git
4. Debuggers.

CREATING A FOLDER AND A CLASS:

1. joe HelloWorld.java -> Create a new file in joe. Name the class how you want
- control k x will save and exit the file

2. in terminal: ls -> lists files in a particular directory




3. mkdir HelloWorld-> make directory (This will be the folder name)

4. mv HelloWorld.java HelloWorld/ - > saving HelloWorld.java in directory HelloWorld

5. cd HelloWorld/

6. ls -l : shows class

7. java HelloWorld: compiles and prints code on screen




2

, i.e. Write Testing class. control-k-x to save and close.




BUILDING LARGE PROJECTS:

How do we efficiently compile larger projects without and IDE?

TOOLS: ant & make

1. ant (from apache)
- Java application to manage (Java) targets/ dependencies
- Uses XML for dependency
- pros: handles inner classes/ package dependencies easily
- cons: don't use it for other development purposes

2. make
- UNIX application - not designed for java (works best for C++)
- uses a text file that lists dependencies
- cons: issues with java inner classes
- use make with a configuration Makefile

make -f makefilename
