Splitting string with pipe character ("|")

📝 Hey there! Splitting strings with the pipe character ("|") can be a bit tricky, but don't worry, I've got you covered! 🧩

If you've been struggling to split values from a string using the pipe character ("|"), you're in the right place. In this blog post, I'll address the common issues you might face and provide simple solutions to help you achieve the expected output. Let's dive in! 💪

To demonstrate the problem, let's take a look at the context provided:

<p>I'm not able to split values from this string:</p>

<p><code>"Food 1 | Service 3 | Atmosphere 3 | Value for money 1 "</code></p>

<p>Here's my current code:</p>

<pre><code>String rat_values = "Food 1 | Service 3 | Atmosphere 3 | Value for money 1 ";
String[] value_split = rat_values.split("|");
</code></pre>

<h3>Output</h3>

<blockquote>
  <p>[, F, o, o, d,  , 1,  , |,  , S, e, r, v, i, c, e,  , 3,  , |,  , A, t, m, o, s, p, h, e, r, e,  , 3,  , |,  , V, a, l, u, e,  , f, o, r,  , m, o, n, e, y,  , 1,  ]</p>
</blockquote>

<h3>Expected output</h3>

<blockquote>
  <p>Food 1<br>
  Service 3<br>
  Atmosphere 3<br>
  Value for money 1</p>
</blockquote>

The Problem: You expected the string to be split into individual values, one per line, but instead, the split() method seems to be splitting every character in the string. 😕

The Solution: The issue lies in the way you're using the split() method. In Java, the pipe character ("|") is a special regex character, so you need to escape it by adding two backslashes ("\|") before it. Here's the corrected code:

String rat_values = "Food 1 | Service 3 | Atmosphere 3 | Value for money 1";
String[] value_split = rat_values.split("\\|");

Now, if you run this code, you'll get the expected output:

<blockquote>
  <p>Food 1<br>
  Service 3<br>
  Atmosphere 3<br>
  Value for money 1</p>
</blockquote>

That's it! You've successfully split the string using the correct syntax. 🎉
