    Default Thought I had this figured out and then.....

    I keep getting this error: PowerJDialog.java:28: error: cannot find symbol
    if (p.Power(pow))
    ^
    symbol: method Power(int)
    location: variable p of type Power
    1 error

    Tool completed with exit code 1

    I have no idea what it means or how to fix it. In my Java book it has no solution to this error, here is my code:

    import javax.swing.JOptionPane;
     
    //Louis Friedmann
    //July 16, 2013
    //This proragm asks for the number and expontant and outputs the result
     
    public class PowerJDialog
    {
     
    	 public static void main(String[] args) {
     
    					 //Variables Declaration
    		 	   		 String inputString; //input
    		 	         int a;  //base number
    		 	         int n; // exponant number
    		 	         int pow; //power
    	         		 String powerResult; // give the reuslt as math
     
    	         		 //Input
    					 inputString = JOptionPane.showInputDialog("Please enter a number");
    					 a = Integer.parseInt(inputString);
     
    					 inputString = JOptionPane.showInputDialog("Please enter a multiplier?");
    					 n = Integer.parseInt(inputString);
     
    					 //Calculation
    					 Power p= new Power(a,n); //create new object
    					 	if (p.Power(pow))
    					 	  {
    					 	    powerResult =  a + " power " + n + " is " + Math.pow(a,n);
    					 	  }
     
    					 //Output
     
    	         		JOptionPane.showMessageDialog(null, powerResult);
     
    	         		 //exits the program
    						         System.exit(0);
    	}
     
     
    }

    Any ideas of what could be going wrong?

    Method names, like Power(), do not usually begin with a capital letter or have the same name as the class unless a constructor. Some resist the use of Java's naming conventions or wonder at the value of using them, but this is one of those occasions when it's clear to guess the source of an error simply because of a naming convention violation.

    Hope this helps. Good luck!
