Answer 1

After I worked on it I got the below code which works.

public void postMethod() throws Exception{
    String result="";
    try{
        Map<String,String> map=new LinkedHashMap<>();
        map.put("key_data","value");
        StringBuilder postdata=new StringBuilder();
        for(Map.Entry<String,String> param:map.entrySet()){
            if(postdata.length()!=0) postdata.append('&');
            postdata.append(URLEncoder.encode(param.getKey(),"UTF-8"));
            postdata.append('=');
            postdata.append(URLEncoder.encode(param.getValue(),"UTF-8"));
        }
        byte[] data=postdata.toString().getBytes("UTF-8");
        String user='admin';
        String pwd='admin';
        String val=user+":"+pwd;
        String url="https://example.com";
        byte[] authEncode=Base64.encodeBase64(val.getBytes());
        String authString=new String(authEncoder);
        URL url1=new URL(url);
        HttpURLConnection urlConnection=(HttpURLConnection)url1.openConnection();
        urlConnection.setRequestMethod("POST");
        urlConnection.setRequestProperty("Authorization","Basic "+authString);
        urlConnection.setRequestProperty("Content-Type","application/x-www-form-urlencoded");
        urlConnection.setRequestProperty("Content-Length",String.valueOf(data.length));
        urlConnection.setDoOutput(true);
        urlConnection.getOutputStream().write(data);
        Reader in=new BufferedReader(new InputStreamReader(urlConnection.getInputStream(),"UTF-8"));
        StringBuilder str=new StringBuilder();
        for(int i;(i=in.read())>=0;)
            str.append((char)i);
        result=str.toString();
    }
    catch(Exception e){
    //handle the exception
    }
    System.out.println(result);
}

I hope this helps and welcome any other method for the above question or optimization of the above code.

postman helps you create code snippet from itself you can use that also:

Now use the code you want :
