            ObjectMapper yamlMapper = new ObjectMapper(new YAMLFactory());

            // Read YAML and convert to JSON
            JsonNode jsonNode = yamlMapper.readTree(yamlString);

            // Create ObjectMapper for JSON
            ObjectMapper jsonMapper = new ObjectMapper();

            // Convert JSON to String
            String jsonString = jsonMapper.writeValueAsString(jsonNode);

            // Print the result
            System.out.println("YAML to JSON Conversion:\n" + jsonString);
        } catch (Exception e) {
            e.printStackTrace();

Explanation:

Dependencies: This code uses the Jackson library for handling JSON and YAML. Make sure to include the necessary dependencies in your project.
YAML to JSON Conversion: The code creates an instance of ObjectMapper with a YAMLFactory to read YAML. It then reads the YAML string and converts it into a JsonNode.
JSON String Output: Another ObjectMapper is created for handling JSON. The JsonNode obtained from the YAML is converted to a JSON string using writeValueAsString().
Print Result: The final JSON string is printed.

This code assumes you have the Jackson library in your classpath. You can add it using Maven or Gradle.
