Java – syntax error: Insert ‘}’ to complete the block

My code keeps making mistakes. I'm making an application to generate a quotation. Who can help me with this? No matter what I try, I will get "syntax error: insert"} "to complete the blocking. When I insert"} ", it gives an error, saying that my code is" inaccessible ". When I add a bracket to make it accessible, it will bring me back to the first error and it's just a loop. It makes me crazy! Can I help you? thank you! This is my code:

   {

    vbjokes = (Button) findViewById(R.id.bjokes);
    vbabout = (Button) findViewById(R.id.babout);
    vtvdisplay = (TextView) findViewById(R.id.tvdisplay);
    vbjokes.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View arg0) {
            // TODO Auto-generated method stub


        }
    });
    vbabout.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View arg0) {
            // TODO Auto-generated method stub
            vtvdisplay.setText("                                                                 Thank you for downloading Punny Jokes! 
            vtvdisplay.setTextColor(Color.BLACK);
            vtvdisplay.setTextSize((float) 20d);

Vtvdisplay. Settext ("thank you for downloading Penny jokes!

It looks like you missed a "); in the end, you copied and pasted it wrong
