Explanation / Answer

// please find the code below

import java.util.Scanner;

class Point {
int X;
int Y;

public Point(int x, int y){
X = x;
Y = y;
}
}

class Triangle {
Point P1;
Point P2;
Point P3;

public Triangle(int x1, int y1,int x2, int y2,int x3, int y3) {
P1 = new Point(x1, y1);
P2 = new Point(x2, y2);
P3 = new Point(x3, y3);
}

String getTriangleType(){

// Comparing squares of length as it is easy to compar that way
// if squares of side length are equal then length is also equal
int l1, l2, l3;

l1 = getSideLengthSquare(P1, P2);
l2 = getSideLengthSquare(P2, P3);
l3 = getSideLengthSquare(P3, P1);

if(l1 == l2 && l1 == l3){
return "Equilateral";
} else if(l1 == l2 || l1 == l3 || l2 == l3){
return "Isosceles";
} else{
return "Scalene";
}
}

int getSideLengthSquare(Point p1, Point p2){
return ((p2.X - p1.X) * (p2.X - p1.X)) + ((p2.Y - p1.Y) * (p2.Y - p1.Y)) ;
}
}

public class Main1 {

public static void main(String[] args) {
  
System.out.println("Please Enter coordinates of traingle ");
Scanner in = new Scanner(System.in);
System.out.println("Please Enter First cordinate x,y ");
int x1 = in.nextInt();
int y1 = in.nextInt();
System.out.println("Please Enter Second cordinate x,y ");
int x2 = in.nextInt();
int y2 = in.nextInt();
System.out.println("Please Enter third cordinate x,y ");
int x3 = in.nextInt();
int y3 = in.nextInt();
  
Triangle triangle = new Triangle(x1, y1, x2, y2, x3, y3);
System.out.println(triangle.getTriangleType());
}
}
