You can use Postman (app) to test requests

WeatherGet Local Temperature: https://openweathermap.org/api

For example: You can hit a URL like : api.openweathermap.org/data/2.5/forecast?lat=35&lon=139

The,response format that you get is called JSON (Javascript Object Notation). You will want to read up more on this (http://codular.com/json).

A good JSON editor is: http://www.jsoneditoronline.org/ It can easily parse it and let you understand the JSON.

Your Java Program will need to parse the JSON to make use of the data. You will definitely need to use a library to parse the Json. GSON is a good library to use, look it up on your own. Use this website for reference:

Ideally, you will want to make a method that you can call in your Java program that return this information to you.

For example a function like: int getWeather(string city) -> returns the current temperature from the Weather API
