Hey Guys check out this code !!!! get two points and return the line !! checked for all occurrences !!!! Please tell me if there are any errors !!!!!!

package line;
import java.util.Scanner;

     Points p1=new Points();
     Points p2=new Points();

     void getLine(Points p1,Points p2){
         System.out.println("Your two points are ");
         System.out.println("("+p1.xCordinate+","+p1.yCordinate+")");
         System.out.println("("+p2.xCordinate+","+p2.yCordinate+")");

         if (yCoeff==0){

         }
         else if (xCoeff==0)
             System.out.println("Y="+p2.yCordinate);
         else{

              op = "+";
         }
         else if ((constant/yCoeff)<0){
                op="";
         }

         System.out.println("Y="+xCoeff/yCoeff+"X" + op + (constant)/yCoeff);
     }
         else
             System.out.println("Y="+ xCoeff/yCoeff+"X");
     }
     }


     void getPoints(){
         System.out.println("Enter your First Point:");
         System.out.print("X=");

         this.p1.xCordinate=input.nextInt();

         this.p2.yCordinate=input.nextInt();
         this.getLine(this.p1,this.p2);
     }


     public static void main(String[] args) {
         do {

         Line l1=new Line();
         l1.getPoints();
         
         System.out.println("Do you want to Continuw with anothe line:(y/n)");
         char state=input.next().charAt(0);
         if (state=='n')
             isContinue=false;

         } while (isContinue=true);

    }
}

class Points {
      int xCordinate;
      int yCordinate;

}
