Here is an example of using the IntNode class from the com.fasterxml.jackson.databind package in the Jackson library for Java:

import com.fasterxml.jackson.databind.JsonNode;
import com.fasterxml.jackson.databind.node.IntNode;

public class Main {
    public static void main(String[] args) {
        JsonNode intNode = new IntNode(42);
        System.out.println(intNode.asText()); // prints "42"
    }
}

In this example, we first import the JsonNode and IntNode classes from the com.fasterxml.jackson.databind package.

Then, we create a new instance of IntNode with a value of 42 and assign it to intNode variable.

Finally, we print the text representation of intNode by calling the asText() method, which returns the string representation of the integer value "42".

You can also use the intValue() method to get the integer value of intNode variable instead of asText().

int value = intNode.intValue();
System.out.println(value); // prints 42
