java - 如何使用 if else 在 TextField 中设置 var 值

Question

请问如何立即将名为 txtUserName 的 TextField 等于“Aime”，并将我的 txtPassword 等于“Joy”，以便它显示消息“用户名和密码匹配!” ？任何人？请帮助我:(

public void actionPerformed(ActionEvent e){
    if (e.getSource()== btnClear){
    txtUserName.setText("");
    }
    if(e.getSource() == btnLogin){
        if (txtUserName.setText="Aime" && txtPassword.setText="JOy")){
            JOptionPane.showMessageDialog(null, "User Name and Password Match!");
        }
        else {
            JOptionPane.showMessageDialog(null, "User Name and Password Invalid!");
        }

Answer 1

这些是需要的小修改。

if (txtUserName.getText().equals("Aime") && txtPassword.getText().equals("Joy")){
            JOptionPane.showMessageDialog(null, "User Name and Password Match!");
}else{
        JOptionPane.showMessageDialog(null, "User Name and Password Invalid!");
}
