The Canadian Forest Service wants to do a simple simulation of the growth and pruning of forests. Each forest has a name and exactly 10 trees. The trees are planted when they are 1' to 5' tall, and each tree has a individual growth rate of 50%-100% per year. For the simulation new trees are constructed randomly within these bounds. A forest is reaped (by lumberjacks) on demand - all trees above a specifed height are cut down and replaced with new trees.

The user interface to the simulation must allow the user to:

Display the current forest (with tree heights to 2 decimal places)

Discard the current forest and create a new forest

Simulate a year's growth in the current forest

Reap the current forest of trees over a user specified height, replacing the reaped trees with random new trees.

Save the information about the current forest to file (named after the forest)

Discard the current forest and load the information about a forest from a file.

The user interface must deal with invalid user input in a graceful way.

Here what a sample run should look like (with the keyboard input shown in italics) ...

Goodbye

I know the code needs to start out with this:

```
import java.util.Scanner;
//=============================================================================
public class ForestryManagement {
//-----------------------------------------------------------------------------
private static Scanner keyboard = new Scanner(System.in);
//-----------------------------------------------------------------------------
public static void main(String[] args) {
```

but other than that I am unsure of what to do as I just started learning java. Any and all help is appreciated.
