The correct answer is: D. no other parameters to that constructor.
When you instantiate an object, you can specify the
values for the object’s parameters. If you do not specify a value for a parameter, the constructor will use the default value for that parameter.If you want to override the default value for a parameter, you must specify a value for that parameter when you instantiate the object. You
do not need to override the default values for any other parameters.For example, consider the following code:
“`class Person {
String name;
int age;
Person(this.name, this.age);
}
“`
The Person constructor has two parameters, name and age. The default value for name is null, and the default value for age is 0.
If you instantiate a Person object without specifying any values for the name and age parameters, the constructor will use the default values:
Person person = new Person();
The person object will have a name of null and an age of 0.
If you want to override the default value for the name parameter, you can specify a value for the name parameter when you instantiate the object:
Person person = new Person("John Doe");
The person object will have a name of “John Doe” and an age of 0.
You do not need to override the default value for the age parameter, because you already specified a value for the name parameter.
The following code is also valid:
Person person = new Person("John Doe", 25);
The person object will have a name of “John Doe” and an age of 25.
In conclusion, if you want to override the default value for a parameter, you must specify a value for that parameter when you instantiate the object. You do not need to override the default values for any other parameters.
