Java Program to Find Line Passing Through 2 Points

class Main
{
   
     // Driver method
    public static void main(String args[])
    {
        IntsPoint x1 = new IntsPoint(3, 2);
        IntsPoint x2 = new IntsPoint(2, 6);
        lines_pts(x1,x2);
    }
    
     static class IntsPoint
    {
        int a,b;
        public IntsPoint(int a, int b) 
            {
                this.a = a;
                this.b = b;
            }
    }
    //find the line passing through 2 points by using equation
   static void lines_pts(IntsPoint x1, IntsPoint x2)
    {
        int x = x2.b - x1.b;
        int y = x1.a - x2.a;
        int z = x * (x1.a) + y * (x1.b);
        if (y < 0)
            System.out.println("The line passing through points x1 and x2 is: " + x + "x - " + y + "y = " + z);
        else 
            System.out.println("The line passing through points x1 and x2 is: " + x + "x + " + y + "y = " + z);
    }
}

Output:

The line passing through points x1 and x2 is: 4x + 1y = 14
