Copy this code and paste it in your HTML

import org.codehaus.jackson.map.ObjectMapper
 
class User 
{
    static class Name{
        String first;
        String last;
    }
 
    Name name
    Boolean verified
    String gender
    byte[] userImage
}
 
String json = """{
  "name" : { "first" : "Joe", "last" : "Sixpack" },
  "gender" : "MALE",
  "verified" : false,
  "userImage" : "Rm9vYmFyIQ=="
}
"""
 
ObjectMapper mapper = new ObjectMapper(); 
User user = mapper.readValue(json, User.class);
 
assert user.name.first == "Joe"
assert user.name.last == "Sixpack"
assert user.gender == "MALE"
assert user.verified == false
assert user.userImage.size() == 7
