scala中Mixin类组合,了解object,trait,class,abstract class

abstract class AbstractPerson{
val name:String
}
class TestPerson extends AbstractPerson{
val name="gmy"
}
trait traitPerson extends AbstractPerson{
def bigName=name.toUpperCase
}
class test extends TestPerson with traitPerson{

}
object test{
def main(args: Array[String]): Unit = {
val p=new test()
println(p.name)
println(p.bigName)
}
}
