Can you call a constructor from another class in Java?

Call One Constructor From Another Within the Same Class in Java. When we want to call one constructor from another constructor within the same class, we use the this keyword . An expression that uses the this keyword must be the first line of the constructor. The order doesn’t matter in the constructor chaining.26 Oca 2021

To call one constructor from another constructor is called constructor chaining in java. This process can be implemented in two ways: Using this() keyword to call the current class constructor within the “same class” . Using super() keyword to call the superclass constructor from the “base class”.

No, you cannot call a constructor from a method. The only place from which you can invoke constructors using “this()” or, “super()” is the first line of another constructor . If you try to invoke constructors explicitly elsewhere, a compile time error will be generated.1 Ağu 2019
