The source code to implement trait Mixins is given below. The given program is compiled and executed on the ubuntu 18.04 operating system successfully.
// Scala program to implement
// trait Mixins
trait SampleTrait {
def sayHello();
}
abstract class AbsClass {
def sayHi();
}
class Test extends AbsClass with SampleTrait {
def sayHello() {
println("Hello world");
}
def sayHi() {
println("Hiiiii");
}
}
object Sample {
def main(args: Array[String]) {
var obj = new Test();
obj.sayHello();
obj.sayHi();
}
}
Output:
Hello world
Hiiiii
Explanation:
In the above program, we used an object-oriented approach to create the program. Here, we created the trait SampleTrait and an abstract class AbsClass. The Sampletrait contains an abstract method sayHello() and AbsClass contains an abstract method sayHi(). Then we extend the Test and implement both methods.
Then we created a singleton object Sample and defined the main() function. The main() function is the entry point for the program.
In the main() function, we created the object of the Test class and called sayHello() and sayHi() method and printed messages on the console screen.
