Hi everybody. So my issues are that every time I run the conversion instead of the results populating on my current frame, the program opens up another frame instead, forcing me to have to move my program out of the way to see it. Also, the results are not clearing when I enter a new temperature. Here is what I got...

Class 1 - 
 
import javax.swing.*;
import java.awt.event.*;
import java.awt.*;
 
public class TempConversions implements ActionListener 
{
JFrame frame; 
public JLabel in1, in2, out1, out2;
JRadioButton celin, celout, fahin, fahout, kelin, kelout;
JPanel top, left, right, bottom;
JTextField textfield;
JTextArea area; 
double results;
 
TempConversions() 
{
//Gets users desired temp to input	
in1 = new JLabel("Original Temp: "); 
textfield = new JTextField(10); 
top = new JPanel(); 
top.add(in1); 
top.add(textfield); 
 
//Input Buttons
in2 = new JLabel(" Input Scale ");//Labels left side.
celin = new JRadioButton("Celcius (\u00B0C)");
fahin = new JRadioButton("Fahrenheit (\u00B0F)");
kelin = new JRadioButton("Kelvin (\u00B0K)"); 
ButtonGroup inputgroup = new ButtonGroup();  
inputgroup.add(celin);                      
inputgroup.add(fahin); 
inputgroup.add(kelin); 
left = new JPanel(new GridLayout(5,1,8,5)); 
left.add(in2);                              
left.add(celin); 
left.add(fahin); 
left.add(kelin); 
 
//Output Buttons
out2 = new JLabel(" Output Scale "); //Labels right side.
celout = new JRadioButton("Celcius (\u00B0C)"); 
fahout = new JRadioButton("Fahrenheit (\u00B0F)"); 
kelout = new JRadioButton("Kelvin (\u00B0K)"); 
ButtonGroup outputgroup = new ButtonGroup(); 
outputgroup.add(celout); 
outputgroup.add(fahout); 
outputgroup.add(kelout); 
right = new JPanel(new GridLayout(5,1,8,5));  
right.add(out2);                             
right.add(celout); 
right.add(fahout); 
right.add(kelout);
 
//Output results
out1 = new JLabel("Converted Temp: "); 
area = new JTextArea(1,8); 
area.setEditable(false); 
bottom = new JPanel(); 
bottom.add(out1); 
bottom.add(area);
 
//Frame layout. Borderlayout method preferred. 
frame = new JFrame("Temp Converter");
frame.add(top, BorderLayout.NORTH); 
frame.add(left, BorderLayout.WEST); 
frame.add(right, BorderLayout.EAST); 
frame.add(bottom, BorderLayout.SOUTH); 
textfield.addActionListener(this);
frame.setSize(400, 300); 
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); 
frame.setVisible(true);
frame.setLocationRelativeTo(null);
} 
 
@SuppressWarnings("unused")
public void actionPerformed(ActionEvent act) 
{ 
TempCalculation cal = new TempCalculation(); 
String s = textfield.getText(); 
double temps = Double.parseDouble(s); 
String e = "No text";
 
if (act.getSource() == textfield) 
{ 
	if (celin.isSelected() && fahout.isSelected()) 
		{ 
		double uinput = Integer.parseInt(s);
		uinput = temps;
		temps=cal.CtoF(temps);
		area.append(temps+ "\u00B0f");
		} 
		else if(celin.isSelected() && kelout.isSelected()) 
			{ 
			double uinput = Integer.parseInt(s);
			uinput = temps;
			temps=cal.CtoK(temps);
			area.append(temps+ "\u00B0k");
			} 
			else if (fahin.isSelected() && celout.isSelected()) 
				{ 
				double uinput = Integer.parseInt(s);
				uinput = temps;
				temps=cal.FtoC(temps);
				area.append(temps+ "\u00B0c"); 
				} 
				else if(fahin.isSelected() && kelout.isSelected()) 
					{ 
					double uinput = Integer.parseInt(s);
					uinput = temps;
					temps=cal.FtoK(temps);
					area.append(temps+ "\u00B0k");
					} 
					else if (kelin.isSelected() && celout.isSelected()) 
						{ 
						double uinput = Integer.parseInt(s);
						uinput = temps;
						temps=cal.KtoC(temps);
						area.append(temps+ "\u00B0c"); 
						} 
						else if(kelin.isSelected() && fahout.isSelected()) 
							{ 
							double uinput = Integer.parseInt(s);
							uinput = temps;
							temps=cal.KtoF(temps);
							area.append(temps+ "\u00B0f");
							}
						else
						{
							area.append(e);
						}
	}
}
@SuppressWarnings("unused")
public static void main(String[] args)  
{ 
	TempCalculation CTempCalcultion = new TempCalculation();
	}
}

and here is the second class...

 
public class TempCalculation extends TempConversions
{ 
//Calculations
//1.	
double CtoF(double temp) 
{ 
	double cf = temp * (1.8) + 32; 
	return cf;
} 
//2.
double CtoK(double temp) 
{ 
	double ck = temp + 273.15; 
	return ck; 
} 
//3.
double FtoC(double temp) 
{ 
	double fc = (temp - 32) * (0.56);
	return fc;
}
//4.
double FtoK(double temp)
{
	double fk = (temp + 459.67) * (0.56);
	return fk;
}
//5.
double KtoC(double temp) 
{  
	double kc = temp - 273.15; 
	return kc; 
}
//6.
double KtoF(double temp)
{
	double kf = temp * (1.8) - 459.67;
	return kf;
} 
}
