Java JLabel - 添加唯一标识符

Question

Is there anyway to add an ID or a unique identifier to a JLabel?

Thanks all

Answer 1

JLabel has a setName method that is inherited from java.awt.Component. You could use this for an ID.

Answer 2

You can call Component.setName on it, or JComponent.putClientProperty , or subclass or use the JLabel object as a key is a Map of some sort.

But probably the way to go is to keep hold of a reference to the original object, so you can write clean, direct code that doesn't have to look the component up.
