我想创建一个单词搜索java程序,每当我输入一个包含通配符的单词时,例如:b * t
我想从我拥有的文本文件中找到适合该单词的所有可能单词。
这是我到目前为止所做的,
Scanner cin = new Scanner(System.in);
System.out.print("Enter a query: ");
String input = cin.nextLine();
try{
String line;
BufferedReader br = new BufferedReader(new FileReader("dictionary.txt"));
while((line = br.readLine()) != null){
if (input.length()==line.length()) {//show all letters in that range
if ('*' != input.charAt(x)) {//check if letters contain '*'
if (line.charAt(x) == input.charAt(x)) {//check if letters match
System.out.print(line+"\n");//show all words that fit criteria
}else{//skip letter
x=+1;
}
}else{//skip
x=+1;
}
}// end if
}// end while
}catch (IOException e){
e.printStackTrace();
}
我可以找到一定长度的所有单词,我只是在努力寻找适合我查询的单词。

我相信这符合您的需求:
public static void main(String [] args){
Scanner cin = new Scanner(System.in);
System.out.print("Enter a query: ");
String input = cin.nextLine();
try{
String line;
BufferedReader br = new BufferedReader(new FileReader("dictionary.txt"));
while((line = br.readLine()) != null){
String[] words = line.split(" ");
for(String w: words) {
String p = "^" + input.replaceAll("\\*", ".*") + "$";
if (w.matches(p)) {
System.out.println(w);
}
}
}
}catch (IOException e){
e.printStackTrace();
}
System.exit(0);
}
