Thread: 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);
	}
}
