Answer 1

I tried with GSON, GSON is directly convert your JSONString to java class object.

Example:

String jsonString = {"phoneNumber": "8888888888"}

create a new class:

class Phone {

@SerializedName("phoneNumber")
private String phoneNumebr;


public void setPhoneNumber(String phoneNumebr) {
this.phoneNumebr = phoneNumebr;
}

public String getPhoneNumebr(){
return phoneNumber;
}

}

// in java

Gson gson = new Gson();
Phone phone = gson.fromJson(jsonString, Phone.class);

System.out.println(" Phone number is "+phone.getPhoneNumebr());
