Java - Methods and Code Reusability

Which of the following is a correct method overloading example in Java?

class Test {
  void show(int a) {}
  void show(int a, int b) {}
  void show(int a) {}
}

AThis code compiles without errors

BDuplicate method show(int a) causes a compile error

CMethod names must be different to overload

DReturn types must differ for overloading

Step-by-Step Solution

Solution:

Step 1: Check method signatures
Two methods have the same name and same parameter list: show(int a).
Step 2: Understand overloading rules
Overloading requires different parameter lists; duplicate signatures cause errors.
Final Answer:
Duplicate method show(int a) causes a compile error -> Option B
Quick Check:
Same parameters = error, not overloading [OK]

Quick Trick: Parameters must differ; identical signatures cause errors [OK]
