I need to get the username from the login.java page and put it in a variable in the account.java JFrame. How can I do this in the Java NetBeans using the Swing?

推荐答案

您可以使用getter和setter方法...

You can use getter and setter methods...

在设置器中设置用户名.并使用login.java对象通过getter在account.java中使用它.

Set the username in a setter. And using object of login.java use it in account.java through getter...

public class login {
    private String username;
    private String password;

    public String getUsername() {
        return username;
    }
    public void setUsername(String username) {
        this.username = this.usernameTextField.getText();
    }
    public String getPassword() {
        return password;
    }
    public void setPassword(String password) {
        this.password = this.passwordTextField.getText();
    }
}

使用login.java对象访问account.java中的getPassword()，getUsername(). 您需要先将login.java对象传递给account.java ...

Using objects of login.java access getPassword(), getUsername() in account.java. you need to pass object of login.java to account.java first...
