    Default Java throwing error with Simple Program

    Can't figure this out at all. I'm getting this error "Static Error: Undefined class 'Variables3'" in Dr. Java when trying to run a file named "Variables3.java".

    Variables3.java contains this code:
    PHP Code:
    public class Variables3
    {
      public static 
    void main(String[] args)
      {
        
    int myInteger 10;
        
    System.out.Println(myInteger);
      }

    The console window is printing out this:
    "javacTask: target release 1.7 conflicts with default source release 1.8"

    When I compile the program, the compile window throws no errors. It says "Compilation completed."

    A printwriter like System.out does not have a method called Println. There is however a method called println, I guess that is what you wanted to write here. Remember, java is case sensitive.
    I dont know if this is the only problem you got but the code looks okay to me.

    I don't know how Dr. Java is configured, but I suspect there's a version mismatch with the compiler (javac) and execution (java) executables. Drop to a console and type both:

    javac -version

    and

    java -version

    and ensure the results match. Report the results here if you need to.

    If the results do match, then dig into the Dr. Java configuration and ensure that both the compiler and execution settings point to the same Java installation. If they don't match, then you have multiple Java installations with paths or environment variables pointing to both, one for JRE and one for JDK, that you need to fix so that both point to the same Java installation.
