Does Java support default parameter values

Java does not support default parameter values in the same way languages like Python or C++ do. That means you can’t define a method like this:

  void greet(String name = "Guest") { ... } // ❌ Not valid in Java

But don’t worry — Java has a different way to handle this: method overloading. Instead of providing default values in the method signature, you write multiple versions of the same method with different parameters.

 Using Method Overloading

public void greet() {
    greet("Guest"); // call the other method with default value
}
public void greet(String name) {
    System.out.println("Hello, " + name);
}

• This mimics default values by providing an overloaded method with fewer parameters.
  
• You can do this with as many parameters as needed, creating a flexible API.
  

 Why Java avoids default parameters

• Java emphasizes clarity and explicit behavior.
  
• Overloading keeps type safety and avoids ambiguity when multiple method signatures are possible.
  

 Other Workarounds

• Use builders or optional parameters with objects.
  
• Pass null and handle default values inside the method logic.
  

So while Java doesn’t let you assign default values directly in the method signature, method overloading gives you a clean and controlled way to get the same result!
