Multiplier

I don't understand what's wrong with the program. Anyone that can help me it will be greatly appreciated.

(Write a program that uses dialog boxes to get two numbers from a user, multiplies the two numbers, and displays the result in two decimal places using another dialog box.)

Code Java:

import javax.swing;
public class MultiplierHB1
{
public static void main(String[] args);
{
	String str1;
	String str2;
	int a; int b; int total;
}
	str1 = JOptionPane.showInputDialog("Please enter a number");
	a = Integer.parseInt(str1);
    //Taking string and converting to integer//
 
    str2 = JOptionPane.showInputDialog("Please enter second number to find the multiplier");
    //Explain to the user as clear as possible to get clarity//
 
    b = Integer.parseInt(str2);
    JOptionPane.showInputDialog(total = a * b %.2f);
    //multiplying the total numbers from the user//
 
    JOptionPane.showInputDialog("Your total is");
	System.exiit(0);
	}
 
}
