How to Resolve a java.lang.AbstractMethodError in Java? Last Updated : 25 Feb, 2024 Summarize Comments Improve Suggest changes Share Like Article Like Report The java.lang.AbstractMethodError is a runtime error in Java that occurs when a class lacks the implementation of the abstract method declared in one of its interfaces or abstract parent classes. This error signifies a mismatch between the expected and actual class hierarchy. Syntax:public interface MyInterface { void myMethod(); } public class MyClass implements MyInterface { // Missing implementation of myMethod }Program to Resolve a java.lang.AbstractMethodError in JavaThe java.lang.AbstractMethodError occurs when a class attempts to invoke an abstract method that should have been implemented by the concrete subclass but isn't. Below is the Program to Resolve a java.lang.AbstractMethodError: Java interface GFG { void myMethod(); } // Class implementing the interface // And providing the implementation class myClass implements GFG { // Implementation of abstract method public void myMethod() { System.out.println("Implementation of myMethod"); } public static void main(String[] args) { // Creating an instance of MyClass myClass obj = new myClass(); // Calling the implemented method obj.myMethod(); } } Output: Implementation of myMethodExplanation of the above Program:We define an interface GFG with the abstract method myMethod().We create a class myClass that implements the GFG interface. This class provides an implementation for myMethod() method.Inside the myMethod() implementation we print the message "Implementation of myMethod".In the main() method we create an object obj of myClass class.We then call the myMethod() method on obj object in which invokes the implemented method in myClass class.When the program is executed and it prints the message "Implementation of myMethod" to the console.
