Here is the simple code sample to understand how REST Callout can be done using apex:

String endPointUrl = 'https://www.google.com/search?q=site:linkedin.com+linkedin+Employee+Size';  
Http h = new Http();
HTTPRequest req = new HTTPRequest();
HTTPResponse resp = new HTTPResponse();
req.setHeader('Content-Type', 'application/xml');
req.setEndpoint(endPointUrl);
req.setMethod('GET');
resp = h.send(req);
String response='';
response = resp.getBody();
system.debug('Response='+response);

Dont forgot to add "https://www.google.com" in your remote site setting.
Let me know if it is heplful.

Here is sample code for POST method:

HttpRequest req = new HttpRequest();
HttpResponse res = new HttpResponse();
Http http = new Http();

req.setEndpoint('http://yourendpoint.com/newPost');
req.setMethod('POST');
req.setBody('name='+EncodingUtil.urlEncode(name, 'UTF-8')+'&country='+EncodingUtil.urlEncode(country, 'UTF-8'));
req.setCompressed(true);

try {
	res = http.send(req);
} catch(System.CalloutException e) {
	System.debug('Callout error: '+ e);
}
