class Triangle
{
double array;
int height;
int length;
public static void main(String [] args)
{
int x = 0;
Triangle [] ta = new Triangle[4];
while(x < 4)
{
ta[x] = new Triangle();
ta[x].height = (x + 1) * 2;
ta[x].length = x + 4;
ta[x].setArea();
System.out.print("triangle "+x+", area");
System.out.println(" = " + ta[x].area);
x = x +1;
}
int y = x;
x = 27;
Triangle t5 = ta[2];
ta[2].area = 343;
System.out.print("y = " + y);
System.out.println(", t5 area = "+ t5.area);
}
void setArea()
{
area = (height * length) / 2;
}
}


Well, the above programme is not compiling ..giving the following error

cannot resolve symbol variable area =System.out.println(" = " + ta[x].area);

cannot resolve symbol variable area =ta[2].area = 343
cannot resolve symbol variable area = System.out.println(", t5 area = "+ t5.area);
cannot resolve symbol variable area =area = (height * length) / 2;

please solve this problem

cheers

double check your code , you did not defined the area variable.
indeed you define it as

and you are using a variable name like area to reference that array variable.

just change the to and you will be fine.
