You need to define the Java bin path first. Please java path is defined well. Than, if your project is in maven please use 

mvn spring-boot:run

on shall/terminal/cmd or your project is gradle, please run the below code

gradle bootRun

You need to right-click on your class that has Main method > Run > Java Application.

The error clearly says that Class not found. You need to compile the code first, try to build the project. Download relevant dependencies and than run it. It will work for sure.

  1. Generate project by using following url https://start.spring.io/
  2. Once project generated extract and import into IDE
  3. If using Eclipse right click of Application.java and run as java
  4. If using STS right click on project and run as spring boot project

You have some special characters in your path. C:\Users\Itzik\Desktop\לימודים\JAVA\demo>

Please unzip a simple directory: c:\mywork\
