Note also that protected fields and methods are used in this class, in order to extend it later (the

Next, create a TwitterRESTClient class:

import java.util.Map.Entry;

import com.google.api.client.http.HttpRequest;
import com.google.api.client.http.HttpRequestFactory;
import com.google.api.client.http.HttpResponse;
import com.google.api.client.http.HttpTransport;
import com.google.api.client.http.UrlEncodedContent;
import com.google.api.client.http.javanet.NetHttpTransport;
public class TwitterRESTClient {
private static final String API_ENDPOINT_URL = " https://api.twitter.com/1.1/";
private final HttpTransport transport;
private final OAuthPostSignatureParametersProvider parametersProvider;
public TwitterRESTClient(
OAuthPostSignatureParametersProvider parametersProvider) {
this.transport = new NetHttpTransport();
this.parametersProvider = parametersProvider;
}

return makeRequest(operation, "GET");

}
public String makeRequest(String operation, Map<String, String> parameters) {
return makeRequest(operation, "GET", true, parameters);
}
public String makeRequest(String operation, String method,
Map<String, String> parameters) {
return makeRequest(operation, method, true, parameters);
}
public String makeRequest(String operation, String method, boolean useOAuth,
Map<String, String> parameters) {
