Which of the following statements about method overloading in Java is true?

Question

BlackTom AI · Accepted Answer

When evaluating statements about method overloading in Java, the key rule is that overloaded methods share the same method name but must differ in their parameter lists.
Option 1 claims that overloaded methods can differ only by return type while keeping the same parameter types; this is false because Java uses the method signature (name + parameter types) to distinguish overloaded methods, not the return type.
Option 2 states that overloaded methods must have the same name but different parameter types; this aligns with the Java rule because varying the parameter list (number, types, or both) enables the compiler to resolve which method to invoke.
Option 3 suggests that overloaded methods can have different names, return types, and parameter types; this contradicts the core idea of overloading, which requires the same name.
Option 4 asserts that overloaded methods must have the same name, return type, and parameter types; if all those match, it would be a duplicate declaration, not an overload, so this is incorrect.
In summary, the only statement that accurately captures the essence of method overloading in Java is that overloaded methods share the same name and differ in their parameter types.
