Mas não quero que o jlist ocupe todo o meu panel, quero que ele fique com tamanho 150,200; como faço isso?

obrigada.

Olá

JList.setBounds(x, y, 150, 200);

Acredito que seja isso

Até mais

O Swing não trabalha assim.

Para saber dimensionar componentes, você deve entender como funcionam os layout managers.
Só com eles você vai ter uma interface gráfica que suporte redimensionamento, multiplos look&feel e seja realmente muiti-plataforma.

Dá uma lida nos textos daqui:
