Except that pbl made a slight typo...nothing major.

	 public void setRate(double rate)
	{
		chosenRate = rate;
	}

	// DECLARE THE CONSTRUCTOR
	 public Furniture
	{
		Scanner input =  new Scanner(System.in);
		System.out.print("What type of wood table are you looking for?");
		System.out.print("Enter " + PINE_CODE + " for Pine table " + OAK_CODE + " for Oak table, or " + MAHOGANY_CODE + " for Mahogany table...");

You need to name every code block...

okay so, i then had to make a second class with a size selection included.
I think i did everything okay except i get one compile error:
I can't seem to fix this, any suggestions?

In your Furniture constructor (from your previous post)

public Furniture

You need to include the parenthesis, even if it won't take any parameters.

public Furniture()

Ahhh, you're getting a StackOverflowError.

This here is the line that is causing it

Furniture woodFurniture = new Furniture();

It is recursively creating a new Furniture Object, and keeps creating more and more Furniture Objects until it eats up all the available space, and dies.

Let me demonstrate what I mean:
1. A Furniture object, f, is created in your main method.
2. This Object then creates another Furniture Object named woodFurniture.
3. This Object also uses the constructor, and in creating a new Object, creates a new Furniture Object.
4. Go to 3

I answered your PM, but I'll post the same reply here since the use of PMs for programming questions isn't generally the right way of going about it.

Anyway, basically your Furniture class is creating an infinite number of copies of itself.

I would suggest removing this line Furniture woodFurniture = new Furniture();

Also

//woodFurniture.setType(furnitureType);
//woodFurniture.setRate(chosenRate);
this.setType(furnitureType);
this.setRate(chosenRate);
//anywhere else you see woodFurniture, replace it with this

Alright i have another issue.
I now have to make a code that accepts the kind of wood as well as the size. This is the code i have made,
however, the size selection doesn't show up.. what am i doing wrong?

import javax.swing.JOptionPane;
public class Furniture2

	 int  size;
	int furnitureType;
	double chosenRate = 0;
	final int PINE_CODE = 1;
	final int OAK_CODE = 2;
	final int MAHOGANY_CODE = 3;
	 final int LARGE_CODE = 4;
	 final int SMALL_CODE = 5;
	final String PINE_WOOD = "Pine table";
	final String OAK_WOOD = "Oak table";
	final String MAHOGANY_WOOD = "Mahogany table";
	final double PINE_RATE = 100.00;
	final double OAK_RATE = 225.00;
	final double MAHOGANY_RATE = 310.00;
	
	{
		

		
		System.out.println("Enter <" + PINE_CODE + "> for a pint table");
		  System.out.println("Enter <" + OAK_CODE + "> for an  Oak table");
		  System.out.println("Enter <" + MAHOGANY_CODE + "> for a Mahogany table");
	 	  
		  System.out.println("What size would you like your table to be?");
		  System.out.println("Enter <" + LARGE_CODE + "> for a large table");
		  System.out.println("Enter <" + SMALL_CODE + "> for a small table");
		  
		  
	   
		 

		  if(furnitureType == PINE_CODE){ 
		 		if( size == LARGE_CODE)
				System.out.println("Large pine table cost is $135.00");
				else
				System.out.println("Small pine table cost is $100.00");
				  }
		else if(furnitureType == OAK_CODE) {
					  if(size == LARGE_CODE)
					System.out.println("Large oak table cost is $260.00");
					else
					System.out.println("Small oak table cost is $225.00");
					}
		else if(furnitureType == MAHOGANY_CODE) {
						  if(size == LARGE_CODE)
						System.out.println("Large mahogany table cost is $345.00");
						else
						System.out.println("Small mahogany table cost is $310.00");
		 		  }	
		else
		 		System.out.println("Invalid selection, please try again.");
		   
	
	 } 
	public static void main(String[] args)  {
		Furniture f = new Furniture();
		  
  }

The reason none of your output shows up is because you have it in a rogue block (see below code). You should make this block the constructor. So before the opening brace, add public Furniture2(). Also, just FYI, your code doesn't get the user input- it just prints output.

 {
		

		
		System.out.println("Enter <" + PINE_CODE + "> for a pint table");
		  System.out.println("Enter <" + OAK_CODE + "> for an  Oak table");
		  System.out.println("Enter <" + MAHOGANY_CODE + "> for a Mahogany table");
		   
		  System.out.println("What size would you like your table to be?");
		  System.out.println("Enter <" + LARGE_CODE + "> for a large table");
		  System.out.println("Enter <" + SMALL_CODE + "> for a small table");
		  
		  
	   
		 

		  if(furnitureType == PINE_CODE){ 
				 if( size == LARGE_CODE)
				System.out.println("Large pine table cost is $135.00");
				else
				System.out.println("Small pine table cost is $100.00");
				  }
		else if(furnitureType == OAK_CODE) {
					  if(size == LARGE_CODE)
					System.out.println("Large oak table cost is $260.00");
					else
					System.out.println("Small oak table cost is $225.00");
					}
		else if(furnitureType == MAHOGANY_CODE) {
						  if(size == LARGE_CODE)
						System.out.println("Large mahogany table cost is $345.00");
						else
						System.out.println("Small mahogany table cost is $310.00");
				   }	
		else
				 System.out.println("Invalid selection, please try again.");
		   
	
	 }
