• Similar to a word processor, but much more powerful

Eclipse• Instructions for installing Eclipse can be found on the

class webpage under “Information and documentation.”

• After being launched Eclipse will ask you to specify the workspace to use. 

• The workspace is a folder used by eclipse to keep all your work. 

Eclipse• Eclipse uses what are called “perspectives”.

• These are different ways in which files can be viewed and manipulated.

• For now, we will be using the default Java perspective.

• To change perspectives: Window → Open Perspective

• To reset: Window → Reset Perspective

Eclipse• To create a program you need to have a project where the

program file will reside.• File → New → Java Project• Name the project• Set project folder as root directory• Default can be changed under “Configure Default”

• To create an actual program• Start in the Java perspective• File → New → Class• Name it• Write code!

Some Quick Tricks

•Edit → Find/Replace

• “Replace With”• Right click on file

CVS

• Concurrent Versions System

• Saves copies of your work to a repository on Grace machines, allowing roll back and anywhere access

• You need a TerpConnect account!!
