Thread: OOP composition - MyPoint and MyTriangle. need hint for building MyTriangle class

Basically i need to build this MyTriangle class. together with the code from MyPoint, i need to test out the following.

when i try to build the constructor part where v1 = (x1, y1) it says my y1 is not a int variable.
also how do i link the two class together?

MyPoint code is as followed:

public class MyPoint {
 
	private int x;
	private int y; 
 
	public MyPoint(){
		x = 0; 
		y = 0; 
 
	}public MyPoint(int x, int y){
		this.x = x; 
		this.y = y; 
 
	}public int getX(){
		return x; 
 
	}public void setX(int x){
		this.x = x; 
 
	}public int getY(){
		return y; 
 
	}public void setY(int y){
		this.y = y; 
 
	}public void setXY(int x, int y){
		this.x = x; 
		this.y = y; 
 
	}public String toString(){
		return "(" + x + ", " + y + ")"; 
 
	}public double distance(int x, int y){
		int xDiff = this.x - x; 
		int yDiff = this.y - y; 
		return Math.sqrt(xDiff*xDiff + yDiff*yDiff); 
 
	}public double distance(MyPoint another){
		int xDiff = this.x - another.x; 
		int yDiff = this.y - another.y;
		return Math.sqrt(xDiff*xDiff + yDiff*yDiff); 
 
	}
}

I don't see a v1, x1, or y1 in the code you posted. Please post the code producing the error AND the entire error message/stack trace, copied from exactly as it appears at your end and pasted into your post.
