Exploring constructors in a Rectangle class

Report a typo

Consider the following Java code for the class Rectangle:

public class Rectangle {
  private int length;
  private int width;

  public Rectangle(int length, int width) {
    this.length = length;
    this.width = width;
  }

  public Rectangle(int size) {
    this(size, size);
  }
}

Which of the following statements are true?

Select one or more options from the list

Instance of the class can be created with only one parameter provided.

The class Rectangle has constructor overloading.

The class Rectangle can't handle a square as a special case of rectangle.

The class will generate a compile-time error due to multiple constructors with the same name.

The second constructor is an example of constructor chaining.
