Thread: Change to JOptionPane

I want to convert this java code to a joption but i am still learning java and i don't know how to do it, can anyone lend me a hand? Here's the code in buffered reader form:

/*

package sitwork;

import javax.swing.*;

public class sitwork {

public static void main(String[] args){

String name = JOptionPane.showInputDialog( "Desired Choice:" );
int choice=0;
while(choice<=7){
System.out.println("1. Miles");
System.out.println("2. Feet");
System.out.println("3. Kilometer");
System.out.println("4. Meter");
System.out.println("5. Inches");
System.out.println("6. Centimeter");
System.out.println("7. Exit");

choice=Integer.parseInt(dataln.readLine());


switch(choice){
case 1:
int m;

System.out.println("Enter Miles: ");
m=Integer.parseInt(dataln.readLine());
System.out.println("Feet: "+" "+ m *5279.85565107);
System.out.println("Kilometer: "+" "+ m*1.6093);
System.out.println("Meter: "+" "+m*1609.3);
System.out.println("Inches: "+" "+m*63358.26781284);
System.out.println("Centimeter: "+" "+m*160930.0002446136);

break;
case 2:
int f;

System.out.println("Enter Feet: ");
f=Integer.parseInt(dataln.readLine());
System.out.println("Miles: "+" "+ f *0.0001893991176);
System.out.println("Kilometer: "+" "+ f*0.0003048);
System.out.println("Meter: "+" "+f*0.3048);
System.out.println("Inches: "+" "+f*12);
System.out.println("Centimeter: "+" "+f*30.48);
break;
case 3:
int k;

System.out.println("Enter Kilometer: ");
k=Integer.parseInt(dataln.readLine());
System.out.println("Feet: "+" "+ k *3280.8399);
System.out.println("Miles: "+" "+ k*0.6213882);
System.out.println("Meter: "+" "+k*1000);
System.out.println("Inches: "+" "+k*39370.07);
System.out.println("Centimeter: "+" "+k*100000);
break;
case 4:
int me;

System.out.println("Enter Meter: ");
me=Integer.parseInt(dataln.readLine());
System.out.println("Feet: "+" "+ me *3.280839);
System.out.println("Miles: "+" "+ me*621.3882);
System.out.println("Kilometer: "+" "+me*1000);
System.out.println("Inches: "+" "+me*39.3700788);
System.out.println("Centimeter: "+" "+me*100);
break;
case 5:
int i;

System.out.println("Enter Inches: ");
i=Integer.parseInt(dataln.readLine());
System.out.println("Feet: "+" "+ i *3.280839);
System.out.println("Miles: "+" "+ i*0.000015783254);
System.out.println("Kilometer: "+" "+i*0.000025349);
System.out.println("Meter: "+" "+i*0.02534);
System.out.println("Centimeter: "+" "+i*2.51);
break;
case 6:
int c;

System.out.println("Enter Centemeter: ");
c=Integer.parseInt(dataln.readLine());
System.out.println("Feet: "+" "+ c *3.280839);
System.out.println("Miles: "+" "+ c*0.000006218797);
System.out.println("Kilometer: "+" "+c*0.000004);
System.out.println("Meter: "+" "+c*0.004);
System.out.println("Inches: "+" "+c*0.3937008);
break;
case 7:
System.exit(0);
break;
default:
System.out.println("INVALID INPUT! ");
break;
}

}


}

}

I already have changed some part of it into JOption but still doesn't work. Kindly please re-post the correct code...

but still doesn't work

Please explain

On your previous thread, a moderator was kind enough to edit your post to add the code tags. how long does it take before you learn to do that yourself?

And as Norm said, 'it doesn't work" is useless. Read more about that here (on another forum's FAQ page)
