    Here you go:

    int currentX1 = 15;
    int currentY1 = 45;
    int currentX2 = 15;
    int currentY2 = 110;
     
    protected void paint(Graphics g) {
     
            g.setColor(211,211,211);
            g.fillRect(0, 0, getWidth(), getHeight());
            g.setColor(0,0,0);
            g.drawString("  Price", 113, 15, Graphics.TOP | Graphics.HCENTER);
            g.setColor(255,255,255);
            g.fillRect(10, 30, 218, 40);
            g.setColor(0);
            g.drawString("Magsad", 100, 80, 0);
            g.setColor(255,255,255);
            g.fillRect(10, 100, 218, 40);
            g.setColor(0,0,0);
            g.setFont(Font.getFont(Font.FACE_SYSTEM, Font.STYLE_BOLD, Font.SIZE_LARGE));
     
            g.drawString(s_text1,currentX1, currentY1,0);
            g.drawString(s_text2,currentX2, currentY2,0);
     
    }
            static boolean b_upText=true;
    	static String s_text1="";
    	static String s_text2="";
    protected void keyPressed(int keyCode){
    		String keyName = getKeyName(keyCode); 
    		if (keyName.equals("DOWN") || keyName.equals("UP")){
    			b_upText=!b_upText;
    		}
    		else
    		{
    			if(b_upText)
    			{
    				s_text1+=keyName;
    			}
    			else 
    			{
    				s_text2+=keyName;
    			}
                            repaint();
    		}
    }
