위 코드는 내 코드입니다. 제목 (학생)과 들판 사이에 공백을 넣고 싶습니다.

프레임의 스냅 샷이 첨부됩니다. 이 레이아웃에 익숙하지 않습니다. 도움을 많이 주시면 감사하겠습니다.

Answer 1

공공 무효 addStudentMember() {

final JPanel showConsoleArea = new JPanel(new FlowLayout(FlowLayout.LEFT)); 
    showConsoleArea.setLayout(new GridBagLayout()); 
    GridBagConstraints c = new GridBagConstraints(); 

    // Add below line of code change appropriate spacing 
    c.insets = new Insets(10, 10, 10, 10);
