When I try to call the methods (Printed, eDelivered, and WillCall) I get the error:

cannot find symbol
symbol: constructor Printed(paramaters)
location: projectname.Printed

and this same error appears in all 3 method calls. the code is as follows:

Main Class

Can someone please explain why my method calls are not working, I have the constructors in place, and everything seems right to me, but I must be overlooking something simple.

A parameter in each of the method calls was off just a bit. I went back through and rewrote the parameters to correctly match the method itself and now it works correctly. NO FURTHER ACTION REQUIRED. THIS THREAD MAY NOW BE CLOSED.

What is a Java method call?

A Java method call is a statement that invokes a specific method from a class or object. This allows the method to perform a specific task or return a value.

What are some common problems that can occur with Java method calls?

Some common problems with Java method calls include passing incorrect arguments, using incorrect method syntax, and not handling exceptions properly.

How can I troubleshoot Java method call problems?

To troubleshoot Java method call problems, you can check the method's syntax, verify that the correct arguments are being passed, and review any error messages or exception handling. Debugging tools such as a debugger or logging statements can also be helpful.

What are some best practices for Java method calls?

Some best practices for Java method calls include using meaningful method names, following proper naming conventions, documenting the method's purpose and parameters, and handling exceptions appropriately.

Can I call a Java method from another method?

Yes, you can call a Java method from another method within the same class or from a different class. This allows for modular and reusable code.
