what is pojo
It stands for Plain old Java Object and basically we use it when we need to represent some data as Java object. So to that we need to create a Java class to represent it's data. For example: { "name" : "ABC", "gender : "Female", "phone : 1234567890 } So we can create a java object with this 3 data and encapsulate them (name, gender, phone) and also we need to create constructor to create object easily So the idea is we want to create a class and eventually we want it to turn into Json file automatically. Without us doing anything.
