How to convert JSON String to java object

Please follow the following steps to know how to convert json String into the java object.
1)First create a maven Project

2)Add jackson dependency in your POM.xml which is shown below

<dependency>
    <groupId>com.fasterxml.jackson.core</groupId>
            <artifactId>jackson-databind</artifactId>
    <version>2.7.4</version>
</dependency>

3)Now Create a class which you want to convert from json to java class object which is shown below

public class Report {
    int code;
    String status;

    public int getCode() {
        return code;
    }
    public void setCode(int code) {
        this.code = code;
    }
    public String getStatus() {
        return status;
    }
    public void setStatus(String status) {
        this.status = status;
    }
}

4)Now we will use ObjectMapper from Jackson to convert json to java which is shown below

import com.fasterxml.jackson.databind.ObjectMapper;
import java.io.IOException;

public class MainDriver {
    public static void main(String[] args) {
        String data="{\"code\":10,\"status\":\"success\"}";
        Report report=jsontoJava(data, Report.class);
        System.out.println("Code is : "+report.getCode());
        System.out.println("Status : "+report.getStatus());
    }
    public static <T> T jsontoJava(String json, Class<T> classType){
        T result=null;
        ObjectMapper objectMapper=new ObjectMapper();
        try {
            result=objectMapper.readValue(json, classType);
        } catch (IOException e) {
            e.printStackTrace();
        }
        return  result;
    }
}

5)Now Please run your code

6)You will see following kind of output on console which is shown below
