//<applet code = KmToM.class width = "500" height =
"700"></applet>
public class KmToM extends Applet implements ActionListener{
TextField t1,t2;
Label l1,l2,l3,l4;
Button b1,b2;
public void init()
{ setBackground(Color.ORANGE);
Font f = new Font("Verdana",Font.BOLD,12);
setFont(f);
l1 = new Label("Enter length of road-1 in metres");
l2 = new Label("Enter length of road-2 in metres");
t1 = new TextField();
t1.setBackground(Color.pink);
t2 = new TextField();
t2.setBackground(Color.pink);
l3 = new Label();
l4 = new Label();
l3.setForeground(Color.blue);
l4.setForeground(Color.blue);
b1 = new Button("Submit");
b2 = new Button("Submit");
setLayout(null);
l1.setBounds(50,50,180,40);
t1.setBounds(250,60,60,30);
b1.setBounds(330,60,60,30);
t2.setBounds(250,130,60,30);
l2.setBounds(50,120,180,40);
b2.setBounds(330,130,60,30);
l3.setBounds(50,200,250,40);
l4.setBounds(50,250,250,40);
add(t1);
add(t2);
add(l1);
add(l2);
add(l3);
add(l4);
add(b1);
add(b2);
b1.addActionListener(this);
b2.addActionListener(this);
}
public void actionPerformed(ActionEvent ae)
{
if(b1==ae.getSource())
{
float r1=Float.parseFloat(t1.getText());
l3.setText("Length of Road-1 in kilometres
is "+r1/1000+"km");
}
if(b2==ae.getSource())
{
float r2=Float.parseFloat(t2.getText());
l4.setText("Length of Road-2 in kilometres
is "+r2/1000+"km");
}
}
}
And here is the output :
