[Solved] Consider this class:class Rectangle { int width, height; Rectangle() { width = 1; height = 1; } Rectangle(int w) { width = w; height = w;... }}What will new Rectangle(5) create? | Java

Java - Constructors

Consider this class:

class Rectangle {
  int width, height;
  Rectangle() { width = 1; height = 1; }
  Rectangle(int w) { width = w; height = w; }
  Rectangle(int w, int h) { width = w; height = h; }
}

What will new Rectangle(5) create?

AA rectangle with width 5 and height 1

BA rectangle with width 1 and height 5

CA square with width and height 5

DCompilation error due to ambiguous constructor

Step-by-Step Solution

Solution:

Step 1: Match constructor call to signature
new Rectangle(5) matches constructor with one int parameter.
Step 2: Understand constructor behavior
That constructor sets width and height both to 5, creating a square.
Final Answer:
A square with width and height 5 -> Option C
Quick Check:
Single-parameter constructor sets both dimensions equal [OK]

Quick Trick: Single int parameter sets width and height equally [OK]

Common Mistakes:

Assuming default height 1 is used
Confusing which constructor is called
Expecting compilation error
