Android :: Call Intent And Put Into Vector?

b = this.getIntent().getExtras();
s = this.getIntent().getStringExtra("DEFAULTTEXT");

public void onClick(View v)
{
String a = "http://152.226.152.156:1010/jsp-examples/test1";
URL url = null;
HttpURLConnection httpurlconnection = null;
try {
url = new URL(a);
httpurlconnection = (HttpURLConnection) url
.openConnection();
httpurlconnection.setDoOutput(true);
httpurlconnection.setRequestMethod("POST");
Toast.makeText(Booking.this, a, Toast.LENGTH_SHORT).show();
Toast.makeText(Booking.this, "Toast1", Toast.LENGTH_SHORT).show();
ObjectOutputStream dos = new ObjectOutputStream(httpurlconnection.getOutputStream());
SendVEctor.add(txtArrivalTime.getText().toString());
SendVEctor.add(txtFerry.getText().toString());
SendVEctor.add(txtStatus.getText().toString());
SendVEctor.add(txtDestination.getText().toString());
SendVEctor.add(s.toString());
dos.writeObject(SendVEctor);
dos.close();

s would be my intent and how would i put it into my SendVEctor?
