<h1>Lecture for February 1st</h1>
|
|
<h2>Control Structures</h2>
|
|
<p>In this class we will talk about three types of control structures</p>
|
|
<ul>
|
|
<li>Sequential</li>
|
|
<li>Selection</li>
|
|
<li>Repetition</li>
|
|
</ul>
|
|
<p>Sequential is what is most familiar to us. Write the lines from top to bottom and it executes it in that order</p>
|
|
<h3>Selection</h3>
|
|
<p>Selection depends on the question of <code>if</code>. </p>
|
|
<p>If it is raining, wear boots</p>
|
|
<pre><code class="language-java">if (raining) {
|
|
wearingBoots = true;
|
|
}</code></pre>
|
|
<p>If you want something to happen also when it is not true, consider an <code>if-else</code> statement</p>
|
|
<p>If the light is off, turn it on.</p>
|
|
<p>Otherwise, turn it on</p>
|
|
<pre><code class="language-java">if (lightIsOn) {
|
|
lightIsOn = false;
|
|
} else {
|
|
lightIsOn = true;
|
|
}</code></pre>
|
|
<p>Sometimes you can have multiple branches depending on a condition. Let us take a stop light as an example</p>
|
|
<pre><code class="language-java">if (light == "red") {
|
|
car.stop()
|
|
} else if (light == "yellow") {
|
|
car.slow()
|
|
} else {
|
|
car.go()
|
|
}</code></pre>
|
|
<h2>String comparison</h2>
|
|
<p>There is a specific method in the <code>String</code> class when it comes to checking for string equality</p>
|
|
<pre><code class="language-java">boolean equals(String s)</code></pre>
|
|
<p>Let us look at an example</p>
|
|
<pre><code class="language-java">String word = "hello";
|
|
boolean ans = word.equals("hello"); // Returns true
|
|
boolean ans2 = word.equals("Hello"); // Returns false</code></pre>
