Criando um Split Pane utilizando Swing

Criando um Split Pane utilizando Swing

O split pane é um componente que separa graficamente dois componentes e permite que o usuário faça os ajustes necessários nesses dois componentes. O split pane pode ser utilizado para dividir componentes na horizontal ou na vertical.

O código abaixo mostra como usar o Split Pane.
