Explanation / Answer

Here We are writing Own class Loan Student

import java.awt.Button;
import java.awt.Frame;
import java.awt.Label;
import java.awt.TextField;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;

public class LoanStudent extends Frame implements ActionListener
{
Label l1,l2,l3;
TextField t1, t2, t3;
Button b1, b2, b3, b4;
public LoanStudent()
{
l1=new Label("Principle");
l2=new Label("Rate");
l3=new Label("Time");
l4=new Label("Interest");

t1=new TextField(10);
t2=new TextField(10);
t3=new TextField(10);
t4=new TextField(10);

b1=new Button("Principle");

b2=new Button("Rate");

b3=new Button("Time");

b4=new Button("Interest");

add(buttons);

setSize(100,100);
setTitle("Bank Loan");
setLayout(new FlowLayout());

public void actionPerformed(ActionEvent ae)
{
int t=0;

double p=0, r=0, i=0;
try
{
p=Double.parseDouble(t1.getText());

}
catch(NumberFormatException e)
{
t1.setText("Invalid Input");
}
try
{
r=Double.parseDouble(t1.getText());
}
catch(NumberFormatException e)
{
t2.setText("Invalid Input");
}
try
{
t=Integer.parseInt(t1.getText());

}
catch(NumberFormatException e)
{
t3.setText("Invalid Input");

}
if(ae.getSource()==b1)
{
t1.setText(String.valueOf(p));
}
if(ae.getSource()==b2)
{
t2.setText(String.valueOf(r));
}
if(ae.getSource()==b3)
{
t3.setText(String.valueOf(t));
}
if(ae.getSource()==b4)
{
i=(p*r)/t;
t4.setText(String.valueOf(i));

}
t1.setText(String.valueOf(p));

}

}
