java – I can not run application in intellij IDEA because 15 errors

Hi, I'm learning to do applications in Java using intellij IDEA and when I do not launch my application, I can not do it. I do not know what to do. I've tried to reinstall all the programs: Java, Java SDK and Intellij IDEA, but not helped. I send you a screenshot with all the errors. Thank you. enter the description of the image here
