## CS 1: Lecture 14 – Logical Operators

Dear students, Our computer can now ponder our data. It can examine order and equality, two operations at the root of all decision making. Before we sign up for something, we ask ourselves if the benefit exceeds the cost. We compare two brands of pasta on price and weight. We scan the details of our […]

## CS 148: Lab 5 – More Methods

Welcome to lab 5! If you have checkpoints from the last lab to show your instructor or TA, do so immediately.

Not exactly, but there’s nothing stopping us from writing our own method to accomplish this task! But before we do that, let me share with you […]

## Eclipse Shortcuts

Eclipse has a lot of keyboard shortcuts and I know hardly any of them. But my students still think I’m an ace. These are the ones I do use on a regular basis, shared so that my students can be aces: Automatically add import statements to classes that live in faraway packages with Control-Shift-O or […]
