Using HTTPClientParams for HttpClient 4.5 - httpclient

Question

I have a code with HttpClient 3.x which uses HTTPClientParams.
HttpClientParams params = new HttpClientParams();
params.setVersion(HttpVersion.HTTP_1_1);
params.setContentCharset(ENCODING);
try {
URI uri = new URI(some-resource);
int port = uri.getPort();
Protocol protocol = null;
if(port == -1){
if(uri.getScheme().compareToIgnoreCase("http") == 0){
port = 80;
protocol = Protocol.getProtocol("http");
}
else if(uri.getScheme().compareToIgnoreCase("https") == 0){
port = 443;
protocol = Protocol.getProtocol("https");
}
}
Protocol.registerProtocol(uri.getScheme(), protocol);
HttpConnectionManager manager = new SimpleHttpConnectionManager();
HttpClient client = new HttpClient(manager);
client.setParams(params);
I have verified that for HTTPClient 4.5 there are not HTTPParam method. How can I upgrade the same? Are there any alternatives?

Please have a look at RequestConfig class
This code should be roughly equivalent to your code above
CloseableHttpClient client = HttpClientBuilder.create()
.setConnectionManager(new BasicHttpClientConnectionManager())
.setDefaultRequestConfig(RequestConfig
.custom()
// Add custom request parameters
.build())
.build();
URI uri = new URI(some - resource);
HttpGet httpGet = new HttpGet(uri);
httpGet.setProtocolVersion(HttpVersion.HTTP_1_1);
try (CloseableHttpResponse response1 = client.execute(httpGet)) {
EntityUtils.toString(response1.getEntity(), Charset.forName(ENCODING));
}
