All programs should be in java. Thank you
Part 1:
You will implement a complete class called Point that describes a point as it may be
used in a graphics application. A point consists of an x and y coordinate, and a color.
Here are the specifications:
Solution
public class Point
{
private int x;
private int y;
private String color;
public void setColor(String s)
{
color=s;
}
public void setX(int x)
{this.x=x;}
public void setY(int y)
{
this.y=y;
}
public int getX()
{return x;}
public int getY()
{return y;
}
public int area()
{return 0;
}
Point(int x,int y,Strig c)
{
thus.x=x;
this.y=y;
color=c;
}
public String toString()
{
return \"x:\"+x+\"y:\"+y+\"color:\"+color;
}
public void translate(int dx,int dy)
{
x=x+dx;
y=y+dy;
}
}
Part 2
public class Circle extends Point
{
private int radius;
public void setRadius(int r)
{
radius=r;
}
public int getRadius()
{return radius;}
public double area()
{
return 3.14*radius*radius;
}
Circle(int r,int x,int y,String color)
{radius=r;
super(x,y,color);
}
public void scaleFactor(int factor)
{radius=radius*factor;
}
public String toString()
{
return \"radius:\"+radius+\" \"+super().toString();
}
}
Part 3
public class Driver
{
public static void main(String args[])
{
Circle[] c=new Circle[3];
Circle c1=new Circle(1,2,3,\"blue\");
Circle c2=new Circle(4,5,6,\"red\");
Circle c3=new Circle(7,8,9,\"yelow\");
c[0]=c1;
c[1]=c2;
c[2]=c3;
translateAll(c,2,3);
}
public static void translateAll(Circle[] c,int dx,int dy)
{
for(int i=0;i<c.length;i++)
{
c.translate(dx,dy);
}
}
}
