so question is: possible switch yellow cross warnings , red cross errors? haven't found it, hope can me.

edit:

i've made test project, , here screenshot: enter image description here

thanks!

it might me because set compiler mark errors used warning. can set in window->preference menu. open , go java->compiler->errorswarnings , check if want be.

you can check compiler menu (java->compiler) if java compiler compliance level set want @chrylis suggested.

otherwise might because program unable compile because of dependency problem might want check build path or jre in run configurations menu.

right click on project -> run -> run configurations.
