I'm glad you got it working.

How can the code be compiled and executed for testing? It is missing some parts.

What is the desired output for the program?

Sorry, I do not know anything about Minecraft. Try asking on a relevant forum.
This forum is for helping with java programming.

Ok, this problem is about finding an algorithm to solve the problem. The algorithm has nothing to do with the java language. It is the steps the computer needs to take.
You need to find the...

Did your instructor give you any hints to help you solve the problem?

Sorry, I do not understand what a group is. You give two examples but do not explain what a group is.
For example, are the 4 1s in red in one group?

What is a "group"? Can you give an example?


Can you post an example of that?

Is that a two dimensional array? Do the number of rows need to be the same as the number of columns?

Can you define what a "group of 1" is?

Here is a discussion on how it might be done:

What have you tried?

This looks like javascript, not java. Try asking on a javascript forum

How does it do that? Your description is generic and could apply to lots of methods.
What does it return after doing all that?

Please post the source code for the classes you are having problems with.
Be sure to wrap all code in code tags.

What is MR jack Pocket? How is java related?

Are you issues about an IDE or about java programming?
I don't know anything about the IDE.

Yes, I have a reasonable understanding of what an interface is and how to use it.

My question is about the Measurable interface. What is it supposed to do? How and why would it be used?
Method...

What is supposed to be in the Object returned by measure? Why does the method return an Object instead of a specific class that has useful data and methods?

What happens when you compile the program? If there are errors, copy the full text and paste it here.
What is the program supposed to do? Where are the values to be displayed? What code is...

This sounds like a problem with using an OS, not a java programming problem.

If the program you want to execute is a server that can be connected to the internet, then a client on another computer...

I added ()s to make it easier to read.

You are welcome. I'm glad you got it working.

The main method is called by the java program to start execution of the class that is passed to it on the command line.
If you enter: java TheClass
then TheClass needs to have a main method.
