How do retrieve the specific value of an AWS Secrets Manager secret?

I have this java code that retrieves the values from a secret:

public class fetchSecrets {
    public static void main(String[] args) {
        String secretId = "test";
        SecretsManagerClient secretsClient = SecretsManagerClient.builder()
                .region(Region.EU_WEST_1)
                .build();
        fetchPassword(secretsClient, secretId);
        secretsClient.close();
    }

    public static void fetchPassword(SecretsManagerClient secretsClient, String secretId) {
        try {
            GetSecretValueRequest valueRequest = GetSecretValueRequest.builder()
                .secretId(secretId)
                .build();
            GetSecretValueResponse valueResponse = secretsClient.getSecretValue(valueRequest);
            String secret = valueResponse.secretString();
            System.out.println(secret);
        } catch (SecretsManagerException e) {
            System.err.println(e.awsErrorDetails().errorMessage());
            System.exit(1);
        }
    }
}

When I run this code, I get:

{"username":"test","password":"password123456"}

How do i output only the value of the password or the username keys?

So expected output is e.g. password123456

Turns out I had to create a json object and pass in the string to extract its value:

try {
    GetSecretValueRequest request = GetSecretValueRequest.builder()
           .secretId(secretId)
           .build();

    GetSecretValueResponse valueResponse = secretsClient.getSecretValue(request);
    String secret = valueResponse.secretString();

    //defining a JSON string     
    Object obj = JSONValue.parse(secret); 
   
    //creating an object of JSONObject class
    //and casting the object into JSONObject type  
    JSONObject jsonObject = (JSONObject) obj;   
 
    //getting values form the JSONObject
    //and casting that values into corresponding types  
    String username = (String) jsonObject.get("username");    

    //printing the values   
    System.out.println(username); 

} catch (SecretsManagerException e) {
    System.err.println(e.awsErrorDetails().errorMessage());
    System.exit(1);
}

Output : password123456

I suggest doing the following: first, create a class called User like this:

public class User {

    private String username;
    private String  password;

    //setter
    void setUsername(String username) {
        this.username = username;
    }

    void setPassword(String password) {
        this.password = password;
    }

    //getter
    String getUsername(){
        return this.username;
    }

    String getPassword(){
        return this.password;
    }
}

Then you can retrieve the password like this:

User user = gson.fromJson(secret , User.class);
System.out.println(user.getPassword());
