Constructor overload

In Java, we're used to having overloaded constructors. For example, let's look at the following Java class, which requires the a parameter and defaults the value of b to 1:

class User { 
    private final String name; 
    private final boolean resetPassword; 
    public User(String name) { 
        this(name, true); 
    } 
 
    public User(String name, boolean resetPassword) { 
        this.name = name; 
        this.resetPassword = resetPassword; 
    } 
}

We can simulate the same behavior in Kotlin by defining multiple constructors using the constructor keyword:

class User(val name: String, val resetPassword: Boolean) {
    constructor(name: String) : this(name, true)
}
