我正在编码hangman class
,并且unexpected type error
有点问题。 this.hidden.charAt(i) = this.original.charAt(i);
中存在此错误。任何帮助将不胜感激。
public class HangmanClass {
private ArrayList<String> words = new ArrayList();
private String word;
private final static char HIDECHAR = '*';
private String original;
private String hidden;
public void HangmanWord(String original){
this.original = original;
this.hidden = this.hideWord();
}
public String getWord() {
words.add("greetings");
words.add("cheese");
words.add("making");
words.add("juvenile");
words.add("car");
word = words.get(new Random().nextInt(words.size()));
return word;
}
private String hideWord() {
StringBuilder sb = new StringBuilder();
for (int i = 0; i < word.length(); i++) {
sb.append(HIDECHAR);
}
return sb.toString();
}
public boolean checkInput(char input){
boolean found = false;
for (int i = 0; i < this.original.length(); i++) {
if (this.original.charAt(i) == input) {
found = true;
this.hidden.charAt(i) = this.original.charAt(i);
}
}
return found;
}
};
最佳答案
String.charAt(int)
不能在赋值语句的左侧使用。而且您不能在Java中更改/更改String
。
请改用StringBuilder.setCharAt(int index, char ch)
。
