Hi I am using Eclipse 20-12 to try to write Java code. Via Java SE Develop Kit 11.0.9. in Windows 10.
I am getting this error

Error: Could not find or load main class MySweetProgram
Caused by: java.lang.ClassNotFoundException: MySweetProgram

public class MySweetProgram {

public static void main(String[] args) {
System.out.println("Hello World!");



and I not including something in the code or possibly compiler was installed wrong ? Thanks in advance

Have you tried putting your class somewhere other than the Default Package (i.e. by creating a New Package and dragging the class into it)? And does this message happen when using Run As->Java Application from inside Eclipse with the class selected?
