Answer 1

는; ImageIO 클래스를 사용하여 이미지를 생성합니다.

Answer 2

클릭했을 때 작업을 수행하는 이미지 (아이콘)를 원한다고 가정합니다. 즉. 두꺼운 직사각형 단추는 원하지 않습니다.

Button myButton = new Button("HELP",Image.createImage("/help.ico")); 

    myButton.getStyle().setBgImage(null); 
    myButton.getStyle().setPadding(0, 0, 0, 0); 
    myButton.getStyle().setBorder(null); 

    myButton.getPressedStyle().setBgImage(null); 
    myButton.getPressedStyle().setPadding(0, 0, 0, 0); 
    myButton.getPressedStyle().setBorder(null); 

OR :
