Class NoSuchMethodError in Java
NoSuchMethodError is thrown from an application if the application tries to call a static or instance method of another class and that class no longer has a method defined. So this error signals that the specified method could not be found.
It is a child class of IncompatibleClassChangeError which is a subclass of LinkageError.
A NoSuchMethodError is thrown in response to an attempt to reference a method that is not defined in the current definition of a class. Usually, this error is caught by the compiler; it can occur at run-time if the definition of a class is changed after the class that references it was last compiled.
The structure of the NoSuchMethodError class is given below:
public class java.lang.NoSuchMethodError extends java.lang.IncompatibleClassChangeError{
//constructor
public NoSuchMethodError();
//constructs an empty NoSuchMethodError object that is an object with no message specified.
public NoSuchMethodError(String message);
//constructs an NoSuchMethodError object with the message specified.
}
The class NoSuchMethodError also inherits methods from class Object and Throwable.
