photoshop does not use java and cs4 isn't supported in high sierra.
you will need to either upgrade photoshop or downgrade macos.

Photoshop does not use Java. For some reason Apple thought that it
did, and Apple puts up the annoying "you must download..." messages
when you try to install or run Photoshop. Apple eventually fixed
that issue, but I think they waited until MacOS 10.8 to do so.

Photoshop CS3, CS4, CS5 and CS6 are still working just fine for most
people on MacOS, so I'm not sure exactly how your system might have
gotten broken, or why the OS is telling you that you need various
Java versions when you do not need Java at all.
...
No, Apple made that mistake on more than a few applications.
Probably because Photoshop's installers used to use Java (back around
CS1, CS2 or so). But running the application has never required Java.
And we can't do anything about Apple's demand for software that our
software don't use or need. (if we could, we would have already
patched the OS). And Apple says they fixed it in later OS versions.

Photoshop CS6 does not use or require Java in any way. Nor do the CS6
installers.
But Apple "helpfully" marked the Adobe CS6 installers as using Java,
even though they don't. So MacOS warns you about Java, tries to
download and install Java, for nothing. Apple has promised to update
their code, one of these days.

CS4 is not useable in High Sierra. All you get is blank screens and
you can't edit anything and/or certain menus that don't work. For
those of you that use Photoshop and Illustrator, there are 2 programs
called Affinity Photo and Affinity Designer that are very comparable
and are available in the macOS App Store for $50 each. They also
support PSD and AI file import. Both of the apps are available for
Mac and Windows, and Affinity Photo is available for iPad with Pencil
support. I have found them to be great replacements for Photoshop and
Illustrator. I haven't found a replacement for InDesign. Thankfully,
my layout needs are not very extensive, so I am using Pages until I
can find something better that's not pricey.
