Nodir Nasirov :
There is a json file with multiple objects:
{
"object1": {
"property": "bar",
},
"object2": {
"property": "foo",
},
"object3": {
"property": "buzz"
}
}
There are 3 classes as well, Object1, Object2 and Object3, how can I extract all 3 as separate objects?
This obviously did not work:
Object1 = gson.fromJson(reader, Object1.class);
Object2 = gson.fromJson(reader, Object2.class);
Object3 = gson.fromJson(reader, Object3.class);
Deadpool :
You just need a wrapper class with these three properties
public class Wrapper {
private Object1 object1;
private Object2 object2;
private Object3 object3;
// getters and setters
}
And then use gson.fromJson to parse json into Wrapper
Wrapper wrapper = gson.fromJson(reader, Wrapper.class);
From Wrapper get all the required attributes
Object1 object1 = wrapper.getObject1();
Object2 object2 = wrapper.getObject2();
Object3 object3 = wrapper.getObject3();
