if文で使用されているintの値をswitch文のif文の内側から変更しようとしていますが、値を変更する方法はありません変数の新しいインスタンスを作成します。switch文のif文をwithからswitch文に変更する
問題があるクラスはメインクラスにあり、コードの残りのクラスは必要ですが、関連するものはarntです。ただし、ユーザーがguiコマンドボックスに数値を入力すると、FramePanelクラスはdecisionChooserメソッドを初期化します。
以下は私のフルコードです。メインクラスの下にあなたがいる場合を見つけて、問題の文を切り替えます場所です。
メインクラス:
public class Main
{
public static void main(String[] args)
{
FramePanel.runLater();
StoryArray.main();
}
public int a1;
public int a2;
public int a3;
public int a4;
public int a5;
public int textNumber;
public String chosenText;
public void decisionChooser()
{
String inputText = FramePanel.commandsField.getText();
FramePanel.commandsField.setText(null);
try
{
textNumber = Integer.parseInt(inputText);
textNumber = textNumber - 1;
if (textNumber == a1 || textNumber == a2 || textNumber == a3 || textNumber == a4 || textNumber == a5)
{
System.out.println(textNumber + " in If");
System.out.println("Entering switch");
switch (textNumber)
{
case 0:
a1 = 70; // this will change a1 for in the if statement
chosenText = StoryArray.storyLine[textNumber];
FramePanel.currentTextArea.append(chosenText + "\n");
break;
case 70:
a1 = 281;
chosenText = StoryArray.storyLine[textNumber];
FramePanel.currentTextArea.append(chosenText + "\n");
break;
default:
break;
}
}
else
{
FramePanel.currentTextArea.append("\nPlease choose a valid page number!\n");
}
System.out.println("Out of If statement");
}
