Return value is getting null from model

Hi i am creating a service of Invoice PO to get the json reponse after verification from classes of service package.
First I have created a model package and classes according to json.
InvoiceRequest is like this--
package com.InvoicePO.newmodel;
import java.util.List;
public class InvoiceRequest {
private List<Records> records;
public List<Records> getRecords() {
return records;
}
public void setRecords(List<Records> records) {
this.records = records;
}
}
Records Class--
package com.InvoicePO.newmodel;
import java.util.List;
import com.fasterxml.jackson.annotation.JsonProperty;
public class Records {
private String Vecv_plant;
private String DBM_Plant;
private String VECV_SO;
private String DBM_PO;

I use Java 11.0.15, Vaadin 14 (Maven/Spring Boot) and my IDE is Eclipse 2022-06 (4.24.0).

On the other hand I have a method call setListToPOJO
public class Utility{
public static void setListToPOJO(List<String> objList, HealthDetails healthDetails){
Methods[] methods = healthDetails.getClass().getDeclaredMethods();
int i = 0;
for(Method method : methods){
if(method.getName().startsWith("set"){
method.invoke(healthDetails, objList.get(i++));
}
}
//include all the try catch methods IllegalArgumentException /
//IllegalArgumentException / InvocationTargetException
}
however i caught an argumentTypeMissmatch
Any Idea how do i solve this without modifying the access Field?
this is the method use to make it work the main class
public class RunMethod{
public static void main(String[] args){
List<String> data = Arrays.asList("object0", "object1", "object2", "object3", "object4", "object5", "object6", "object7", "object8", "object9", "object10", "object11", "object12", "object13", "object14", "object15", "object16", "object17", "object18", "object19", "object20", "object21", "object22", "object23", "object24", "object25", "object26", "object27", "object28", "object29", "object30", "object31", "object32", "object33", "object34", "object35", "object36", "object37", "object38", "object39", "object40", "object41", "object42", "object43", "object44", "object45", "object46", "object47", "object48", "object49", "object50", "object51", "object52", "object53", "object54", "object55", "object56", "object57", "object58", "object59", "object60", "object61", "object62", "object63", "object64", "object65", "object66", "object67", "object68", "object69", "object70", "object71", "object72", "object73", "object74", "object75", "object76", "object77", "object78", "object79", "object80", "object81", "object82", "object83", "object84", "object85", "object86", "object87", "object88", "object89", "object90", "object91", "object92", "object93", "object94", "object95", "object96", "object97", "object98", "object99", "object100", "object101", "object102", "object103", "object104", "object105", "object106", "object107", "object108", "object109", "object110", "object111", "object112", "object113", "object114", "object115", "object116", "object117", "object118", "object119");
HealthDeatils healthDetails = new HealthDetails();
Utility.setListToPOJO(data,healthDetails);
}
}
Below is the output
Error Message (Edited):
java.lang.IllegalArgumentException: argument type mismatch
at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)
atsun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39)

at java.lang.reflect.Method.invoke(Method.java:592)

The cause is that the parameter you passed, objList.get(i++) is not the type the method you invoke required.
modify you code to
for(Method method : methods){
String value = objList.get(i);
try {
if(method.getName().startsWith("set"){
method.invoke(healthDetails, value);
i++;
}
} catch (Exception e) {
e.printStackTrace();
System.out.println("Value is: " + value); // show which value is wrong
}
}
This would check which value type is wrong.
On the other hand, for the wrong order of methods. I suggest you change objList from List<String> to Map<String, Obj>, the key is the name of the method you want to invoke, like Id, Name. Then you invoke it by just add set in front of it.
for (Map.Entry<String, String> entry : map.entrySet())
{
Object value = entry.getValue();
Method method = healthDetails.getClass().getDeclaredMethod("set"+entry.getKey(), value.getClass());
method.invoke(healthDetails, value);
}

Your HealthDetails class have 124 properties and 124 setter methods but you are populating data list with only 120 elements causing ArrayIndexOutOfBoundsException while calling the setter methods through reflection.
If we provide arguments for all the setter methods in that list your code will work without any issue.
Below is the working modified code:
public class RunMethod {
public static void main(String[] args) {
List<String> data = Arrays.asList("id", "name", "age", "height", " object0", "object1", "object2", "object3", "object4", "object5", "object6", "object7", "object8", "object9", "object10", "object11", "object12", "object13", "object14", "object15", "object16", "object17", "object18", "object19", "object20", "object21", "object22", "object23", "object24", "object25", "object26", "object27", "object28", "object29", "object30", "object31", "object32", "object33", "object34", "object35", "object36", "object37", "object38", "object39", "object40", "object41", "object42", "object43", "object44", "object45", "object46", "object47", "object48", "object49", "object50", "object51", "object52", "object53", "object54", "object55", "object56", "object57", "object58", "object59", "object60", "object61", "object62", "object63", "object64", "object65", "object66", "object67", "object68", "object69", "object70", "object71", "object72", "object73", "object74", "object75", "object76", "object77", "object78", "object79", "object80", "object81", "object82", "object83", "object84", "object85", "object86", "object87", "object88", "object89", "object90", "object91", "object92", "object93", "object94", "object95", "object96", "object97", "object98", "object99", "object100", "object101", "object102", "object103", "object104", "object105", "object106", "object107", "object108", "object109", "object110", "object111", "object112", "object113", "object114", "object115", "object116", "object117", "object118", "object119");
HealthDetails healthDetails = new HealthDetails();
Utility.setListToPOJO(data, healthDetails);
}
}
Utility Class
public class Utility{
public static void setListToPOJO(List objList, HealthDetails healthDetails) {
System.out.println(objList.size());
Method[] methods = healthDetails.getClass().getDeclaredMethods();
System.out.println("methods array size " +methods.length);
int i = 0;
for (Method method : methods) {
if (method.getName().startsWith("set")) {
System.out.println(method.getName());
try {
method.invoke(healthDetails, objList.get(i++));
} catch (IllegalAccessException e) {
e.printStackTrace();
} catch (InvocationTargetException e) {
e.printStackTrace();
}
}
}
}
}

A different approach.
Currently, your code reads:
Methods[] methods = healthDetails.getClass().getDeclaredMethods();
int i = 0;
for(Method method : methods){
if(method.getName().startsWith("set"){
method.invoke(healthDetails, objList.get(i++));
}
}
The implicit assumption here is: the setter methods returned by getDeclaredMethods() are in the same order as your parameters (List<String> objList).
First of all, that assumption is wrong. There is no guaranteed order in that array.
But beyond that: when you know the order of elements in your list you simply don't need to use reflection at all.
You just do:
for (int i=0; i < objList.size(); i++) {
String parm = objList.get(i);
switch (i) {
case 0: healthDetails.setId(parm); break;
case 1: healthDetails.set...(parm); break;
and so on.
The point is, as stated multiple times: using a flat list means that you (somehow) must know in which order the arguments come in. And then you can simply use that order to determine the required setter method.
In other words: the code example you are showing implies that you do not need to use reflection to solve this problem. At all. Your idea to use reflection only buys you complexity, nothing else.
( of course: when the input would be a Map<String, String> that provided the field names, things would be different. but as long as you use a list with a fixed order, there is no need and point using reflection! )
Given the update, the only real answer there is: don't use 100+ fields named data1, data2, ... that is what arrays/list are for.

Spark: Mapping RDD to RDD returning nullpointer Exception

In my logic, I am attempting to map a JDBCRDD - TopologyRDD over to a JavaBean of JavaRDD.
TopologyRDD.count() returns the CORRECT number of rows, so I know the data was loaded in correctly. I also mapped TopologyRDD to a List just to confirm the data was loaded in, and it loaded in the data just fine.
Problem: When mapping TopologyRDD to MODEL_TOPOLOGYRDD, the MODEL_TOPOLOGYRDD.count() action is returning a nullpointer exception error.

The only problem I can see with this code is if any line2[i] are null.
And if(line2[i].toString() == null) won't work because toString() never returns null for the Object class.
I see that you want any null values to become empty strings, so try this as your for-loop instead
for(int i = 0; i < line2.length; i++){
line2[i] = (line2[i] == null) ? "" : String.valueOf(line2[i]);
}
Note the use of String.valueOf, which altogether avoids the NullPointerException when trying to get the String value of objects.

JSON Parsing with GSON

I have the following Json string.How to parse this kind of Json using Gson in Java?Any help would be appreciated.
{
"acclst":[{
"accountInfoData":[{
"userId":9,
"rid":"1-Z5S3",
"acnme":"acc_1234.",
"actpe":"Fabricator / Distributor",
"mph":"2660016354",
"euse":"Biofuels",
"com":"0",
"sta":"Active",
"stem":"BBUSER5",
"wsite":"",
"fax":"",
"zone":"",
"crted":"BBUSER4",
"statusX":1,
"partyId":0,
"address":[]
}
]
}
],
"conlst":[],
"actlst":[],
"prolst":[],
"code":"200"

your Gson getter/Setter class will be

to fetch
String json= "your_json_string";
Gson gson= new Gson();
sample objSample=gson.fromJson(json,sample.getClass());
thats it

You have to use JSONObject to parse this json in android.
Take a look at the following link.
http://developer.android.com/reference/org/json/JSONObject.html

Android already contains the required JSON libraries. You can use a valid string or a file for input. Here is code and explanation taken from here:
import org.json.JSONArray;
import org.json.JSONObject;
import android.app.Activity;
import android.os.Bundle;
public class JsonParser extends Activity {
private JSONObject jObject;
private String jString = "{\"menu\": {\"id\": \"file\", \"value\": \"File\", \"popup\": { \"menuitem\": [ {\"value\": \"New\", \"onclick\": \"CreateNewDoc()\"}, {\"value\": \"Open\", \"onclick\": \"OpenDoc()\"}, {\"value\": \"Close\", \"onclick\": \"CloseDoc()\"}]}}}";//write your JSON String here
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
try {
parse();
} catch (Exception e) {
e.printStackTrace();
}
}
private void parse() throws Exception {
jObject = new JSONObject(jString);
JSONObject menuObject = jObject.getJSONObject("menu");
String attributeId = menuObject.getString("id");
System.out.println(attributeId);
String attributeValue = menuObject.getString("value");
System.out.println(attributeValue);
JSONObject popupObject = menuObject.getJSONObject("popup");
JSONArray menuitemArray = popupObject.getJSONArray("menuitem");
for (int i = 0; i < 3; i++) {
System.out.println(menuitemArray.getJSONObject(i)
.getString("value").toString());
System.out.println(menuitemArray.getJSONObject(i).getString(
"onclick").toString());
}
}
}
