        setFullScreenMode(true);
    }

        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);

    }
    protected void keyPressed(int keyCode){
 
       keyName = getKeyName(keyCode);     
       if (keyName.equals("DOWN")){
              currentX=15;

       }
       else if(keyName.equals("UP")){

       }
       else{
           key();
       }
       repaint();
       }
 
 
  public String key(){
 
       if(keyName.equals("0")){
        bufferText = "0";
        text = (text.length()>=23)?( text) :( text + bufferText);
       }

       }
       else if(keyName.equals("4")){
           bufferText = "4";
           text = (text.length()>=23)?( text) :( text + bufferText);
       }
       else if(keyName.equals("5")){

       }
       else if(keyName.equals("8")){
           bufferText = "8";
           text = (text.length()>=23)?( text) :( text + bufferText);
       }
       else if(keyName.equals("9")){
           bufferText = "9";
           text = (text.length()>=23)?( text) :( text + bufferText);
       }
     //  else if (keyName.equals("DOWN")){
      //     currentX=15;
     //      currentY=110;
    //   }
     //  else if(keyName.equals("UP")){
     //        currentX = 15;
     //        currentY = 45;
     //  }
       else{
           text = keyName;
       }
           return text;
       }
 
    }

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();
		}
}
