我想将jcomp1连接到void类somma

import java.awt.*;
import java.awt.event.*;
import java.util.Scanner;

import javax.swing.*;
import javax.swing.event.*;

@SuppressWarnings({ "unused", "serial" })
public class Calcolatrice extends JPanel {
    private JButton jcomp1;

        public Calcolatrice() {
        //construct components
        jcomp1 = new JButton ("Somma");
    }

    void somma(){
        String val1 = jcomp5.getText();
        String val2 = jcomp6.getText();
        String sum = val1 + val2;
        System.out.println(sum);
    }

我试过：

jcomp1.addActionListener(new ActionListener() { 
  public void somma(ActionEvent e) { 
        String val1 = jcomp5.getText();
        String val2 = jcomp6.getText();
        String sum = val1 + val2;
        System.out.println(sum);
  } 
} );

但似乎不起作用。。。有什么想法吗？我刚开始编写代码，我认为这是一个简单的项目，但我已经有麻烦了。为此，请你尽可能解释清楚好吗？谢谢您。
