[Solved] Find the problem in this code:class A { A() { System.out.print("A"); } } class B extends A { B() { this(); System.out.print("B"); } } | Java

Java - Constructors

Find the problem in this code:

class A {
  A() { System.out.print("A"); }
}
class B extends A {
  B() { this(); System.out.print("B"); }
}

AConstructor B should be static

BMissing super() call in B constructor

CNo problem, code compiles and runs

DRecursive constructor call causes compile error

Step-by-Step Solution

Solution:

Step 1: Analyze constructor call in B
B's constructor calls this(), which calls itself recursively without end.
Step 2: Understand compiler behavior
Recursive constructor calls cause compile-time error due to infinite recursion.
Final Answer:
Recursive constructor call causes compile error -> Option D
Quick Check:
Constructor recursion = compile error [OK]

Quick Trick: Avoid recursive constructor calls with this() [OK]
