Used same settings in .prettierrc and settings.json file except

"[java]": {
        "editor.defaultFormatter": "esbenp.prettier-vscode"
},

and added default formatter for java files as follows

1. Open command Palette... Ctrl + Shift + P (mac command + shift + P) and
2. search Format Document With...
3. select Configure Default Formatter...
4. choose Language Support for Java(TM) by Red Hat

Working sample

Now if I add following in settings.json

"[java]": {
        "editor.defaultFormatter": "esbenp.prettier-vscode"
},

got the same issue as of yours

So the solution will be to remove above settings from the settings.json file.

settings.json file

{
    "files.eol": "\n",
    "terminal.explorerKind": "external",
    "terminal.integrated.shell.osx": "/bin/zsh",
    "editor.minimap.enabled": true,
    "workbench.colorTheme": "Visual Studio Dark",
    "editor.fontSize": 14,
    "editor.fontFamily": "source code pro, Menlo, Monaco, 'Courier New', monospace",
    "terminal.external.osxExec": "iterm.app",
    "window.zoomLevel": 1,
    "go.useLanguageServer": true,
    "editor.formatOnSave": true,
    "editor.suggestSelection": "first",
    "vsintellicode.modify.editor.suggestSelection": "automaticallyOverrodeDefaultValue",
    "breadcrumbs.enabled": false 
}

P.S. Make sure Java Extension Pack vscjava.vscode-java-pack is installed, used v0.12.1
