Java – add custom attributes to JTree nodes

I need to store some data in the JTree node Can I add custom attributes to the node to save my data?

Solution

You can create a node class with the extension defaultmutabletreenode, which contains data properties

public final class MyDatanode extends DefaultMutableTreeNode {
    private final MyData myData;

    public MyDatanode(MyData myData) {
        this.myData = myData;
    }

    public MyData getMyData() {
        return myData;
    }
}
