Check the help menu's software installation/uninstallatin options and make sure Java is still installed. — nanofarad

Closing the file's tab and re-opening it fixed it for me.

(I actually closed all the tabs...)

I faced the same issue all of a sudden after a commit/update project operation.

The point is, default editor of Eclipse has changed somehow and we have to set it back to normal.

Try the below method,
1. Goto Windows -> Click Preferences
2. From the Preferences window goto General -> Editors -> Click File Associations
3. You can choose the default editor for *.java files here

When I first opened Preferences, 'Text editor' was set as the default editor for .java files and then I changed it back to 'Java Editor'.

Now it works perfectly fine.

You probably have a corrupt installation or you have recently installed a corrupt plugin.

The following steps might help.

In your Install window,

view your "already installed" plugins.
select the "Installation History" tab.
select a previous stable configuration
Click the "Revert" button

TLDR; open another workspace, then come back to the original workspace.

Ok this is odd, but for me, all the highlighting suddenly went away for Java files. I explored all of these ideas here, with no effect. I created a new workspace, planning to move everything to it. I realized that can be a pain to move many projects over, so I went back into the original workspace to look at some settings, and poof - the highlighting was working again.

I have one java class file like a text editor.

I tried following,

Select the respective java class file from eclipse.
Right click on the file and mouse hover on "Open with".
Select java editor.

Now its works.
