java - 如何在循环中声明标签？

如何在循环中自动创建对象？为什么此代码不起作用？

String strLbl[] = {"Model","Weight","Length","Age","Number of keys"};
JLabel lbl[] = new JLabel[5];

for (int i=0;i<strLbl.length;i++){
    JLabel lbl[i] = new JLabel(strLbl[i]);
}

最佳答案

数组元素分配不允许使用类型声明：

JLabel lbl[i] = new JLabel(strLbl[i]);

应该

lbl[i] = new JLabel(strLbl[i]);
