Enable JSON Pretty Print in Java Jackson

To enable pretty print in Java Jackson for JSON String make use of the enable() method with SerializationFeature.INDENT_OUTPUT as an argument.

import com.fasterxml.jackson.databind.ObjectMapper;
import com.fasterxml.jackson.databind.SerializationFeature;

import java.io.IOException;

public class EnumToJsonJackson {

    public static void main(String[] args) throws IOException {

        ObjectMapper objectMapper = new ObjectMapper();
        objectMapper.enable(SerializationFeature.INDENT_OUTPUT);
        Employee employee = new Employee("Sam",29,"Insurance");
        String employeeJson = objectMapper.writeValueAsString(employee);
        System.out.println(employeeJson);
    }
}

{
  "empName" : "Sam",
  "empAge" : 29,
  "empDept" : "Insurance"
}
