    Default Java cant find symbols?

    Here is the code that is giving me problems. im trying to write code that will find the distence between two points. but i get the cannot find symbol error on lines 27-29(when i start doing math).

    import java.lang.*;
    import java.util.Scanner;
     
    public class Program
    {
    	public static void main (String[] args)
    	{
      	double x1, y1, x2, y2; // coordinates of two points
      	double distance;   	// distance between the points
     
      	Scanner scan = new Scanner(System.in);
     
      	// Read in the two points
      	System.out.print ("Enter the coordinates of the first point " +
               	"(put a space between them): ");
      	x1 = scan.nextDouble();
      	y1 = scan.nextDouble();
     
      	System.out.print ("Enter the coordinates of the second point: ");
      	x2 = scan.nextDouble();
      	y2 = scan.nextDouble();
     
      	// Compute the distance
     double a, b, c, d, e, f;
            a = x2 + x1;
            b = y2 + y1;
            e = Math.java.pow(a,2);
            f = Math.java.pow(b,2);
            distance = Math.java.sqrt((e + f));
     
      	// Print out the answer
      	System.out.println(distance);
    	}
    }

    Default Re: Java cant find symbols?

    Well, when you call the Math.java.pow you don't actually need to add the .java in there, that's why it's giving you the cannot find symbol error, afterwards you're going to run into initialization errors, when you compute the distance, you're program is going to try to compute d as
    Math.sqrt((e+f));
    however, e and f have not yet been initialized!
