How Can I Pass Array Arguments to Methods in Java Without Declaring a Separate Variable?

In-Line Array Declaration: A Quick Fix for Argument Lists

As you work with arrays in Java, you might come across situations where you need to pass an array as an argument to a method. Typically, you would declare an array, assign values to it, and then pass it as shown below:

<code class="java">String[] strs = {"blah", "hey", "yo"};
m(strs);</code>

However, if you're only using the array for this one method call and don't need to store it for later use, you might be wondering if there's a way to simplify the process. Fortunately, Java allows you to declare arrays in-line when making method calls.

This can be achieved using the new keyword followed by the desired array type and the array elements within curly braces. For instance, you can replace the code mentioned earlier with:

<code class="java">m(new String[]{"blah", "hey", "yo"});</code>

This seemingly simple change allows you to avoid creating a named variable for the array and directly pass its elements as arguments to the method. It's a handy technique that reduces code clutter and makes your code more concise.
