Java - Memory Management Basics

Identify the problem in this Java code related to garbage collection:

public class FinalizeTest {
  public static void main(String[] args) {
    Object obj = new Object();
    obj.finalize();
  }
}

AThe code will cause a compile-time error

BObject cannot be instantiated directly

CCalling finalize() directly is discouraged and may cause unexpected behavior

DGarbage collection is forced by calling finalize()

Step-by-Step Solution

Solution:

Step 1: Understand finalize()
finalize() is a method called by the garbage collector before reclaiming an object.
Step 2: Analyze direct call
Calling finalize() directly is discouraged because it does not trigger garbage collection and may cause side effects.
Step 3: Evaluate other options
Object cannot be instantiated directly is incorrect; Object can be instantiated. The code will cause a compile-time error is wrong; code compiles. Garbage collection is forced by calling finalize() is false; finalize() does not force GC.
Final Answer:
Calling finalize() directly is discouraged and may cause unexpected behavior -> Option C
Quick Check:
Do not call finalize() manually [OK]

Quick Trick: Never call finalize() directly; JVM calls it [OK]
