How do we loop Java object

Question

Below is the output of my code...

System.out.println(CompanyStructure.get());

 Output:    [com.some.spf.b2bac.facilit.api.parameter.GetkingResult$king@2357662d, com.some.spf.b2bac.facilit.api.parameter.GetkingResult$king@633ced71, com.some.spf.b2bac.facilit.api.parameter.GetkingResult$king@312aac03]

I tried to convert to json string.

jsonString = CommonUtil.convertFromEntityToJsonStr(CompanyStructure.get());

System.out.println(jsonString);

Output:[{"customerId":"1"},{"customerId":"2"},{"customerId":"3"}];

I want to fetch all names with the ids 1,2,3 through sql iam using postgresql. how do i fix this?

if you are new to Java, you should start at the beginning, not start with utils, converters, Json, ... — Stultuske, Nov 27 '15 at 13:31

You get the Object representation of object. To loop though the objects that get() method use a for each:

for (GetkingResult result : CompanyStructure.get()) {
    if (result.getId() == 1) // do something
}

Also you can override the toString() method of the GetkingResult object.
