如何更改check变量，以便它不检查LastNameField是否为空，以便检查lastNameField是否等于lastNamefield？

private boolean isInputValid() {
    String errorMessage = "";

    if (firstNameField.getText() == null || firstNameField.getText().length() == 0) {
        errorMessage += "No valid German word!\n"; 
    }
    if (lastNameField.getText() == null || lastNameField.getText().length() == 0) {
        errorMessage += "No valid English word!\n"; 
    }

      //if (pw.equals(gpw) == true) {
    if (errorMessage.length() == 0) {
        return true;
    } else {
        // Show the error message.
        Dialogs.create()
            .title("wrong spelling")
            .masthead("Please correct!")
            .message(errorMessage)
            .showError();
        return false;
    }

如果你想要一个方法来检查字段是否等于除非是空的，请使用：

if (!"lastNamefield".equals(lastNameField)){
    errotMessage+= "No valid English word!\n";
}

或者问你问题是否正确，很难理解，你想要什么！

将功能从更改为相同的检查
