我的任务
分享运行时提示以下错误该怎样解决?
我是这样建立一个新类的,
class newRed extends JLabel implements ListCellRenderer{}
但是jb8提示
Class app.newRed should be declared abstract; it does not define method getListCellRendererComponent(javax.swing.JList, java.lang.Object, int, boolean, boolean) in interface javax.swing.ListCellRenderer at line 67

就是你的类newRed中需要加方法getListCellRendererComponent(javax.swing.JList, java.lang.Object, int, boolean, boolean),因为你实现了javax.swing.ListCellRenderer 接口，所以你要实现javax.swing.ListCellRenderer 中的方法getListCellRendererComponent（javax.swing.JList, java.lang.Object, int, boolean, boolean)，而现在你没有实现该方法，当然要声明成abstract class喽！
