Trait similar to interface in Java but there are differences trait can inherit trait and in trait can write abstract methods, you can also implement the method instance as follows
Trait Walk
{

Def walk () {}
}
Class Person extends Walk
{
println ("Hello-----")
Override Def walk () {println ("Let's Have a Walk")}
}
Trait Run extends Walk
{
def run ()
{
println ("Gofor A walk and run around")
}
}
Object Hellotrait {
def main (args:array[string]): Unit = {
Val tt = Newperson with Run
Tt.run ()
}
}
Printing results:
Hello-----
