    Default Can't figure out JTextArea. Please Help!

    I'm at wits end. First of all, I'm a beginner and am really struggling with this. I'm at the very end of my assignment and am supposed to append the output.

    My code looks like this-

    do {
    strcost=JOptionPane.showInputDialog("Enter cost (>0) :");
    cost=Integer.parseInt(strcost);
    }while(cost<=0);//end of 1st do statement


    do {
    strresidual=JOptionPane.showInputDialog("Enter residual value(>0and<cost):");
    residual=Integer.parseInt(strresidual);
    }while(residual<=0||residual>cost);//end of 2nd do statement



    do {
    struseful_life=JOptionPane.showInputDialog("Enter useful life (>0): ");
    useful_life=Integer.parseInt(strresidual);
    }while(useful_life<0);//end of 3rd do statement






    //Decimal Format
    DecimalFormat precisionTwo = new DecimalFormat("0.00");
    JTextArea outputTextArea= new JTextArea(7,55);


    JTextArea txtArea = new JTextArea("JTextArea example ", 10,34);


    outputTextArea.append("\t\t" + "Depreciation Schedule" );



    for (int x=1;x<=useful_life;x++)
    {
    year_dep=dep_cost/useful_life;
    accum_dep+=year_dep;
    carry_val=cost-accum_dep;



    JTextArea txtArea1 = new JTextArea("JTextArea example ", 10,34);
    outputTextArea.append(x+"\t"+cost);
    }



    How can I get this to show? Thanks in advance.

    You have to add it to a window (a JFrame or a JDialog).
