Why are lambas better than anonymous classes?

Question

Java

Lamba expressions require the interface to contain only 1 method, while using an anonymous class it can contain as many methods as desired. What is the point of using lamb expressions then?

Answer 1

Even without going deep into the jungle, it is obvious that the lambda is more compact.
than an anonymous class

someButton.addActionListener(new ActionListener() {
  public void actionPerformed(ActionEvent e) {
      JOptionPane.showMessageDialog(this, "Hello!")
  }
});

Answer 2

They are better for brevity.
