我试图在三个不同的JFrame中使用来自一个类的数据。例如，我创建了MVCE。在此示例中，我拥有Person类，其中包含一些信息。我想在两个不同的JFrame（Screen1和Screen2）中捕获此信息，并在第三个JFrame（Screen3）中展示它们。我的实现在下面的代码中进行了描述，但是代码无法按预期运行
主要：
package teste;
public class Teste {
public static void main(String[] args) {
Screen1 sc1 = new Screen1();
sc1.setVisible(true);
}
}
人员班级：
package teste;
public class Person {
String name;
String age;
public Person(String name, String age){
this.name = name;
this.age = age;
}
public void setName(String name) {
this.name = name;
}
public String getName(){
return this.name;
}
public void setAge (String age) {
this.age = age;
}
public String getAge(){
return this.age;
}
}
Screen1：
package teste;
public class Screen1 extends javax.swing.JFrame {
public Screen1() {
initComponents();
}
@SuppressWarnings("unchecked")
// <editor-fold defaultstate="collapsed" desc="Generated Code">

我应该怎么做才能将一个对象的信息存储在不同的JFrame中，并在另一个JFrame中显示相同的信息？
