Question

How to set a default value to function parameters in Scala

Answer 1

def print(name: String = "Ty Coon"): Unit = {
  println(s"Hello, $name!")
}

// Calling the function without an argument uses the default value
print() 

// Calling the function with an argument overrides the default value
print("Scala") 
 
   
   
/*
run:
     
Hello, Ty Coon!
Hello, Scala!
 
*/
