In constructor overloading all constructors should have the same class but with a different set of ________.
Show Hint
- Access specifiers
- Classes
- Return type
- Parameters
The Correct Option is D
Solution and Explanation
Constructor overloading means defining more than one constructor in the same class. All these constructors have the same class name, because a constructor must always have the same name as the class. However, they must differ from each other in the list of arguments they accept.
Step 2: Recall the rule for overloading.
In Java, overloading is achieved when methods or constructors have the same name but a different parameter list. The difference may be in:
- number of parameters,
- type of parameters,
- or order of parameters.
Step 3: Compare the given options.
- (A) Access specifiers: Incorrect. Constructors may have different access specifiers, but this is not the basis of overloading.
- (B) Classes: Incorrect. Constructor overloading happens within the same class, not different classes.
- (C) Return type: Incorrect. Constructors do not have any return type.
- (D) Parameters: Correct. Overloaded constructors must differ in their parameter lists.
Therefore, in constructor overloading, all constructors belong to the same class but have a different set of parameters.
Final Answer:Parameters.

- Character String
Assertion and Reasoning
Assertion (A): The substring() method modifies the original String.
Reason (R): The substring() method can extract part of a String from a specific index.
