私は絞首刑執行人のアプリケーションを書いており、文字列内の各文字 (推測されている単語) を "-" で非表示にするコードを書かなければならないところです...そして、たくさんの質問を投稿しましたくわでそれを行うと、私の返信の1つは次のとおりです。
public class HangmanWord {
private static final char HIDECHAR = '_';
private String original;
private String hidden;
public HangmanWord(String original) {
this.original = original;
this.hidden = this.createHidden();
}
private String createHidden() {
StringBuilder sb = new StringBuilder();
for (int i = 0; i < this.original.length; i++) {
sb.append(HIDECHAR);
}
return sb.toString();
}
public boolean check(char input) {
boolean found = false;
for (int i = 0; i < this.original.length; i++) {
if (this.original[i].equals(input)) {
found = true;
this.hidden[i] = this.original[i];
}
}
return found;
}
//getter and setter
}
public class TestClass() {
public static void main(String[] args) {
String secret = "stackoverflow";
int wrongGuesses = 0;
HangmanWord hngm = new HangmanWord(secret);
System.out.println(hngm.getHidden()); // _____________
if (hngm.check('a')) {
System.out.println(hngm.getHidden()); // __a_________
}
else {
wrongGuesses++;
}
//... and so on...
}
}
私はこのコードを私のコードで使用しようとしましたが、多くのエラーが発生し、私のコードでは機能しないという結論に達しました。私のコードでは、人がボタンをクリックすると、文字が単語に含まれているかどうかを示すメッセージが表示される配列ボタンを作成しました...今、このコードを私に与えない場所に置き換えたいと思いますメッセージですが、文字を再表示し、文字がない場合は画像を変更する必要があります
可能であれば、それが私のコードで機能しなかった理由を誰かが説明できますか、または誰かが私に何をすべきかを説明してもらえますか...
私のボタン配列:
public JButton getButton(final String text){
final JButton button = new JButton(text);
button.addActionListener(new ActionListener(){
public void actionPerformed(ActionEvent e){
if(original.toUpperCase().indexOf(button.getText())!=-1){
JOptionPane.showMessageDialog(null, "Your word does contain " + text );
}
else{
JOptionPane.showMessageDialog(null, "There is no " + text );
error++;
if(error >= 0) imageName = "hangman1.jpg";
if(error >= 1) imageName = "hangman2.jpg";
if(error >= 2) imageName = "hangman3.jpg";
if(error >= 3) imageName = "hangman4.jpg";
if(error >= 4) imageName = "hangman5.jpg";
if(error >= 5) imageName = "hangman6.jpg";
if(error >= 7) imageName = "hangman7.jpg";
}
}
});
return button;
}
