In Java, When we are creating a new instance of the class, the constructor of the class will be called. If a class doesn't have a constructor then it will assume there's a default constructor. But constructors are used to assign some initial values to class fields.
Ex:
public class Employee{
private int empID;
private String name;
public Employee(){
this.empID = 1
this.name = "Un-defined"
}
}
We all know that we cant have two constructor in a class, with the same name and same parameters but a different data-type. But while i m analyzing this limitation, suddenly a doubt arise to me whether we can have two constructors with a single parameter, but the data Type of these parameters are different.
Ex:
public class Employee{
// Constructor 1
public Employee(int empID){
}
// Constructor 2
public Employee(String name){
}
}
Ex:
public class Employee{
private int empID;
private String name;
public Employee(){
this.empID = 1
this.name = "Un-defined"
}
}
We all know that we cant have two constructor in a class, with the same name and same parameters but a different data-type.

}
