    Can understand whats wrong with this simple code.

    I'm sort new to Java programing, and I created this simple converter, but when I try to complie it, it gives me an exception error, could some one tell me how to correct this code.

    Code:
     import java.text.*;
    import javax.swing.*;
    
    public class Converter
    {
    	private final static double EURO = .8295577, YEN = 115.614, CAD = 1.17781;
    	
    	public static void main (String[] args)
        {
    	 	String input =null;
    	 	double US= 0.0;
    	 	DecimalFormat twoPrecision = new DecimalFormat("0.00");
    	    input() = 0
     		
    		try{
    	
    		    
    		     US = Double.parseDouble (input);
    			 System.out.print("US to Euro: ");
    			 System.out.println(twoPrecision.format(US * EURO));
    	       
    	       
    	         US = Double.parseDouble (input);
    			 System.out.print("US to Yen: ");
    			 System.out.println(twoPrecision.format(US * YEN));
    		
    		
    		     
    	         US = Double.parseDouble (input);
    			 System.out.print("US to Cad: ");
    			 System.out.println(twoPrecision.format(US * CAD));
    		
    		}
    		catch(NumberFormatException e)
    		{
    			JOptionPane.showMessageDialog(null,
    			                 "You must enter a number",
    			                 "Input data error",
    			                 JOptionPane.ERROR_MESSAGE);
    		}
    	}
    }

    The compliler reports the error t line 14, which is under "input( ) = 0" and above "try {"

    Error: ',' expected
