Depuis Tiger (java 5.0 ou 1.5 …), la structure du langage java \u00e0 int\u00e9gr\u00e9 l’ellipse.<\/p>\n

Voici un exemple d’utilisation
\n
\nJPanel mkEntry(String label, javax.swing.JComponent... jc)
\n{
\nJPanel p = new JPanel(new FlowLayout());
\np.add(new JLLabel(label));
\nfor (javax.swing.JComponent comp: jc)
\np.add(comp);
\nreturn p;
\n}<\/p>\n

void test()
\n{
\nJPanel p = new JPanel();
\np.add(mkEntry(\"test\", new JTextField(), new JButton(\"valider\"));
\n}
\n<\/code><\/p>\n

Bon malheureusement on est oblig\u00e9 de n’avoir qu’un seul param\u00e8tre avec ellipse mais perso je trouve cela plus \u00e9l\u00e9gant que d’utiliser un tableau cr\u00e9er d’un c\u00f4t\u00e9 puis de l’autre. Au passage cela revient au m\u00eame que de cr\u00e9er un tableau (puisque ce qu’on r\u00e9cup\u00e8re est un tableau) mais l’\u00e9criture en est simplifi\u00e9.<\/p>\n","protected":false},"excerpt":{"rendered":"
