Use special characters</strong></p> <p>Java provides several special characters that can be used to represent arrows, as follows: </p> <ul> <li>Left arrow: <code><</code></li><li>Right arrow:<code>></code> </li> <li>Up arrow:<code>^</code> </li> <li>Down arrow:<code>v</code> </li> </ul> <p>#To enter these characters, simply enter them directly into the code. For example: </p> <div class="code" style="position:relative; padding:0px; margin:0px;"><pre class="brush:php;toolbar:false"><code class="java">System.out.println("← → ↑ ↓");</code></pre><div class="contentsignin">Copy after login</div></div> <p><strong>2. Use Unicode escape sequences </strong></p> <p>Unicode escape sequences are a special syntax for representing Unicode characters. You can use this syntax to represent arrow characters in Java code. The following is an example of how to use Unicode escape sequences to represent arrows: </p> <ul> <li>Left arrow: <code>"\u2190"</code> </li> <li>Right arrow: <code>"\u2192 "</code> </li> <li>Up arrow: <code>"\u2191"</code> </li> <li>Down arrow: <code>"\u2193"</code> </li> </ul> <p>To enter these characters, use the following syntax: </p> <div class="code" style="position:relative; padding:0px; margin:0px;"><pre class="brush:php;toolbar:false"><code class="java">System.out.println("\u2190 \u2192 \u2191 \u2193");</code></pre><div class="contentsignin">Copy after login</div></div> <p>In most cases, it is more convenient to enter arrows using special characters. However, if you need to use specific Unicode characters, you can use Unicode escape sequences. </p>
