Which class is super class of every class

Can you use this and super both in constructor

Answer :
super() – calls the base class constructor (or call a super class constructor)
this() – calls current class constructor (constructor in the same class)

  • Both this() and super() are constructor calls
  • Constructor must always be the first statement
  • We can not have two statements as first statement
  • Either we can call super() or we can call this() from the constructor, but not both
  • If both were allowed you could end up calling the super constructor twice
