Failed to instantiate java.util.list using constructor no_constructor with arguments

by

When you see the error message “failed to instantiate java.util.list using constructor no_constructor with arguments”, it means that a List object (from the Java utility class java.util.List) could not be created using the specified constructor called “no_constructor” with the given arguments.

To understand this error, let’s consider an example:

import java.util.List;
import java.util.ArrayList;

public class Main {
  public static void main(String[] args) {
    List<Integer> numbers = new List<Integer>(10);
    numbers.add(1);
    numbers.add(2);
    numbers.add(3);
    
    System.out.println(numbers);
  }
}

In this example, we are trying to create a List of Integers using the constructor with one argument, which specifies the initial capacity of the List. However, this code will result in the error “failed to instantiate java.util.list using constructor no_constructor with arguments”.

The reason for this error is that the List interface in Java is just an interface and cannot be directly instantiated. In order to create a List object, you need to use a class that implements the List interface, such as ArrayList, LinkedList, etc.

Here’s the corrected version of the code using the ArrayList class:

import java.util.List;
import java.util.ArrayList;

public class Main {
  public static void main(String[] args) {
    List<Integer> numbers = new ArrayList<Integer>();
    numbers.add(1);
    numbers.add(2);
    numbers.add(3);
    
    System.out.println(numbers);
  }
}

In this corrected code, we create an ArrayList object instead of using the List interface directly. Now, the code will work as expected and the List of Integers will be printed correctly without any error.
