You can't create a method swap, so that after calling swap(x,y) the values of x and y will be swapped.
You can however write a method that swaps two items in an array or list if that's what you want. It relies on the fact that x will pass into swap before y is assigned to x, then x is returned and assigned to y. Because it relies on parameter assignment on invocation, there is a fear that maybe somewhere, somehow, some implementation of Java might get it wrong.


And I am amused that this 5 year old answer, in the same 10 minute span that you responded to my comment, gained a +1 on your answer, and also a +1 on your comment. Java uses pass-by-value scheme which means when compiling the program up to swap(x, y), it a new x, y will be assigned in memory and hence you are referencing the newly created variable. Because it has attracted low-quality or spam answers that had to be removed, posting an answer now requires 10 reputation on this site.

You can also change highlight of matching symbols like [] () {} <> to white, not sure if that would help.
You could create such a method for mutable classes by swapping their contents?, but this would not change their object identity and you could not define a general method for this. As it relies on parameter assignment on invocation, any project featuring this method will sooner or later run into a bug because of it. This means that any changes made to the object inside a method will be visible on the outside (it also means that passing an object to a method does not copy the object's contents, so passing a 1M-element array does not copy 1M objects). Of course, with the wealth of Collection classes, i can't imagine ever needing to use this in any practical code. After the step is done, since it does NOT appear later, it will be collected and disappeared. If you reside in an EU member state besides UK, import VAT on this purchase is not recoverable.


However reassigning the variable that refers to the array will not be visible on the outside (meaning if you do something like arr1 = arr2 inside the method, this will not have any visible effect on the outside). The point of answers is to provide options, not just for everyone to regurgitate the same answer over and over.
And you so carefully print out the values, but obviously did not actually run your code, to see what the values are.
In fact, there are freebies and deep discounts galore - if you know where to look and whom to ask. So using a shift for a swap is a valid type of swap and wasn't an already provided answer, so i submitted it.
