Answer / Deepak Nigam

In Scala, an auxiliary constructor (also known as secondary constructor or helper constructor) is a constructor defined within a class that calls another primary constructor. Auxiliary constructors are used when you want to simplify the syntax for creating objects by providing multiple ways of initializing the object's state. For example:nn```scalanclass MyClass(val field1: String, val field2: Int) {n def this(field2: Int) = this("default", field2)n}n// Creating objects with auxiliary constructorsnval obj1 = new MyClass("defaultValue", 10)nval obj2 = new MyClass(20)n```
