如何将方法打印到 JavaFX 中的文本字段中，方法输出是整数？
我有这个类，它可以制作骰子，我想将数字打印到文本字段中。
import java.util.Random;
public class Dice {
public Die Die1 = new Die(6);
public Die Die2 = new Die(6);
public int throwDice(){
Die1.throwDie();
Die2.throwDie();
return(Die1.diceEyes+Die2.diceEyes);
}
public void isItaPair(){
if(Die1.diceEyes==Die2.diceEyes)
System.out.println("Its a pair, throw again.");
throwDice();
}
class Die {
private final int diceSides;
public int diceEyes;
private Random randomEyes = new Random();
public Die(int diceSides){
this.diceSides = diceSides;
}
public void throwDie(){
diceEyes = randomEyes.nextInt(diceSides)+1;
}
}
}
这是我的 JavaFX Controller 类，我想将 Die1.throwDice() 的结果打印到文本字段 dice_field 中。
import java.net.URL;
import java.util.ResourceBundle;
import javafx.event.ActionEvent;
import javafx.fxml.FXML;
import javafx.fxml.Initializable;
import javafx.scene.control.Button;
import javafx.scene.control.Label;
import javafx.scene.control.TextArea;
import javafx.scene.control.TextField;
import moole15gop_1.Dice;
import moole15gop_1.Player;
public class FXMLDocumentController implements Initializable {
@FXML
private TextField user1;
@FXML
private TextField user2;
@FXML
private TextArea game_text1;
@FXML
private TextArea game_text2;
@FXML
private Button start_btn1;
@FXML
private Button start_btn2;
@FXML
private Button game_btn;
@FXML
private Label game_label;
@FXML
private TextField dice_field;
@Override
public void initialize(URL url, ResourceBundle rb) {
}
@FXML
private void start_action1(ActionEvent event) {
user1.setText(user1.getText());
System.out.println(user1.getText());
if(user1.getText().isEmpty()){
game_label.setText("You need to enter a username for the first player!");
}
else
{
game_text1.setText("Your username is " + user1.getText() + " and you have " + Player.playerMoney + ". You start at position " + Player.position);
}
}
@FXML
private void start_action2(ActionEvent event) {
user2.setText(user2.getText());
System.out.println(user2.getText());
if(user2.getText().isEmpty()){
game_label.setText("You need to enter a username for the second player!");
}
else
{
game_text2.setText("Your username is " + user2.getText() + " and you have " + Player.playerMoney + ". You start at position " + Player.position);
}
}
Dice die1 = new Dice();
@FXML
private void game_action(ActionEvent event) {
}
}
当 game_action 事件被激活时，应该打印该方法。
感谢您提前提供的帮助。
最佳答案
只需将从方法返回的 int 转换为 string，然后将其打印到文本字段。
使用
dice_field.setText(Integer.toString(new Dice().throwDice()));
或者
dice_field.setText(String.valueOf(new Dice().throwDice()));
