For example, such program will have error, "type List takes Type parameters".
import java.io._
class
class Point(val xc: List, val yc: List)
{
var x: List= xc
var y: List = yc
def move()
{ val result=x.intersect(y)
println ("Length of intersection" + result.length);
}
}
object Demo {
def main(args: Array[String])
{
val pt = new Point(List("a","u","r"),List("a","q","r"));
pt.move();
}
}
You need to write something like:
import java.io._ class
class Point(val xc: List[String], val yc: List[String])
{ var x: List[String]= xc var y: List[String]= yc
def move()
{ val result=x.intersect(y)
println ("Length of intersection" + result.length);
} }
object Demo { def main(args: Array[String])
{ val pt = new Point(List("a","u","r"),List("a","q","r"));
pt.move();
}
}
I wrote about the solutions to some problems I found from programming and data analytics. They may help you on your work. Thank you.
