Can you Declare Arrays Directly Within Method Calls?

In-line Array Declarations in Method Calls

When passing an array as an argument to a method, it's common practice to declare the array explicitly before making the call. However, in some cases, it may be desirable to declare the array in-line within the method call itself.

To accomplish this, simply use the new keyword to create a new array instance and initialize it with the desired elements. For example, suppose you have a method m() that takes an array of strings as an argument. Instead of declaring a named variable for the array, you can pass an anonymous array directly to the method:

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

This in-line declaration avoids the need to declare a separate variable for the array, which can be useful when the array is used only once and does not need to be referenced later in the code.
