    Default Please help! Passing variables between modules.

    I have altered my code. Please let me know if I am any closer. I can't get variables to pass from checkModel and checkYear to printResults. This is what the code is supposed to do:

    The Insurance module calls the checkModel module which prompts the user for a car model and returns a code that indicates whether the car is insurable. If the model is insurable, the Insurance module then calls the checkYear module, which prompts for a year manufactured and returns a code that indicates whether the car is insurable. The Print Results module tells the user whether the car can be insured.

    import java.io.*;
     
    public class Insure
    {
    	// declare global scope variables
    	private BufferedReader input = new BufferedReader(new InputStreamReader(System.in));
    	private String inputString;
     
     
    	public Insure()throws IOException{
    		//I-O-P
    		initialize();
    		insureProcess();
    		cleanUp();
    	}	
     
     	public void initialize() 
    	{
    		System.out.println("Enter car information to see if it is insurable:");
    		System.out.println();
     
    	}// end initialize
     
    	public void insureProcess() throws IOException
    	{
     
    		// declare local variable for car choice
    		String car;
    		boolean insurable;
    		int year;
     
    		// Check Model for insurability
     
    		System.out.println("Enter a car model: ");
    		inputString = input.readLine();
                    	car = inputString;
     
     
    		// Check Year for insurability
     
    		System.out.println("Enter a year: ");
                                    inputString = input.readLine();
                                    year = Integer.parseInt(inputString);
     
    		// Print Results
     
    	}// end insureProcess
     
    	public boolean checkModel(String car, boolean insurable)
    	{
    		if (car.equals("Ford") || car.equals("Chevy") || car.equals("Toyota"))
    			insurable = true;
    		else
    			insurable = false;
    		return insurable;
    	}//end checkModel
     
    	public boolean checkYear(int year, boolean insurable)
    	{
    		if(year >= 1990)
    			insurable = true;
    		else
    			insurable = false;	
    		return insurable;
    	}// end checkYear
     
    	public void printResults(boolean checkModel, boolean checkYear, boolean insurable)
    	{
    		if(checkModel == true && checkYear == true)
    			System.out.println("Insurable");
    		else
    			System.out.println("Not insurable");
     
    	}// end printResults
     
     
    	public void cleanUp()
    	{
    		System.out.println();
     
    	}// end cleanup
     
    	public static void main(String [] args) throws IOException // main method
    	{
    		new Insure();
     
    	} // end the main method
     
    } // end the program

    Please post your code in code tags. You can learn how here and then edit your post.

    Then, explain what you mean by "having trouble." Explain what your code is supposed to do, what it's doing, post a sample run (if possible) and describe how it doesn't satisfy the requirements. Don't make us guess.

    You will have to actually call the method if you want it to run
