I'm trying to convert a wrapper back to string, but for some reason I can't seem to get my variable to drop into my method correctly. Here's what I have:

Conversion.java (Java Class File)

/*
 * Conversion.java
 *
 * Created on March 2, 2005, 6:38 PM

package Chapter6Project1;


public class Conversion 
{
    
    /** Creates a new instance of Conversion */
    public Conversion() 
    {
    }  
    
    public Integer stringToInteger1(String s) throws Exception 
    {
        int i = Integer.parseInt(s);    
            
        Integer iwResult = new Integer(i);
        
        System.out.println(i);
        return iwResult;
    }
    
    public Double stringToDouble1(String t) throws Exception
    {
        double d = Double.parseDouble(t);
        
        Double iwResult2 = new Double(d);
        
        System.out.println(d);
        return iwResult2;
    }
    
    public String wrapperToString(Integer u) throws Exception
    {
        
        String str = u.toString();
        String iwResult3 = new String(str);
        System.out.println("test " + str + iwResult3 + u);
       // String iwResult3 = toString(sresult);
        return iwResult3;
    }
    
}

ConversionTester.java (Main)

package Chapter6Project1;

public class ConversionTester
{
    public ConversionTester()
    {
        
    }

    public static void main(String[] args) throws Exception
    {
            Conversion aConversion = new Conversion();
            aConversion.stringToInteger1("5");
            aConversion.stringToDouble1("5.5");
            aConversion.wrapperToString("6");
           // aConversion.wrapperToString("8");
            Integer u = new Integer("6");
            
    }
}

As you can see, I can pass the Integer and Double through thier methods, but for some reason the wrapperToString method I can't exactly pass and Integer through (hence the commented out aConversion statement in the ConversionTester file).

TIA
