non static variable from static context error

[chopficaro]

in this class i have a constructor and a main() function for testing the constructor
theres a couple things stopping me from testing it in the command prompt tho
the post data is a string with an ampersand in it and when i try to pass it to the main function in the command prompt it thinks that the ampersand means something, i dont know how to "escape" it
also, i would like to know how to pass a value from the constructor to main() so i can print string test, i tried putting it outside both meathods into the class but it gave me non static context error

//takes am address, and post data, and returns the html as a string
import java.net.*;
import java.io.*;
import java.lang.*;
public class UrlToString
{
	public String test = "";
	public static void main (String[] args) throws Exception
	{
		//enter url and post data in cmd prompt to test
		new UrlToString  (test,args[0],args[1]);
		System.out.println(test);
	}
	//paramaters of returned string, address to get it from, and post data in th for of variable1=value1&variable2=value2...
	UrlToString (String returnString, String inAddr, String rawData) throws Exception
	{
		returnString = "";
		//connection variables
		String agent = "Mozilla/4.0";
		String type = "application/x-www-form-urlencoded";
		HttpURLConnection connection = null;
		String encodedData = URLEncoder.encode( rawData, "UTF-8");
		//connect
		try 
		{
			URL searchUrl = new URL(inAddr);
			connection = (HttpURLConnection)searchUrl.openConnection();
			connection.setDoOutput(true);
			connection.setRequestMethod("POST");
			connection.setRequestProperty( "User-Agent", agent );
			connection.setRequestProperty( "Content-Type", type );
			connection.setRequestProperty( "Content-Length", Integer.toString(encodedData.length()) );
			OutputStream os = connection.getOutputStream();
			os.write( encodedData.getBytes() );
			os.flush();
			os.close();
			//check if theres an http error
			int rc = connection.getResponseCode();
			if(rc==200)
			{
				//no http response code error
				//read the result from the server
				
				InputStreamReader in = new InputStreamReader(connection.getInputStream());
				BufferedReader br = new BufferedReader(in);
				String strLine;
				//Read File Line By Line
				while ((strLine = br.readLine()) != null)
				{
					returnString = returnString.concat(strLine);
					System.out.println(strLine);
				}
				return;
			}
			else
			{
				System.out.println("http response code error: "+rc+"\n");
				return;
			}

		}
		catch( IOException e )
		{
			System.out.println("search URL connect failed: " + e.getMessage());
			e.printStackTrace();
		}
	}
}

Your stated problem is with regard to an ampersand in a command line parameter, and using the command line parameters in the construction of an instance of a class. So why did you post about 50 lines of code relating to making a network connection?

To get better help sooner, post a SSCCE (Short, Self Contained, Correct (Compilable), Example) that demonstrates the problem.

tldr
lol
but seriously tho the problem is in the first 5 lines of code
