我的程序显示匹配结果,但我想将结果排序为最佳匹配、次佳匹配等等。
我的文本文件包含以下行:
red or yellow
red'
黄色'
所以如果我搜索red or yellow
::我得到以下结果
'red or yellow
red
yellow
。所以我想要做的是将找到的结果排序如下:
- “红黄”100%匹配
- “红色” 40% 匹配
- “黄色” 40% 匹配
任何帮助表示赞赏。我的代码如下:
public static void main(String[] args) {
// TODO code application logic here
String strLine;
try{
// Open the file that is the first
// command line parameter
FileInputStream fstream = new FileInputStream("C:\\textfile.txt"");
// Get the object of DataInputStream
DataInputStream in = new DataInputStream(fstream);
BufferedReader br = new BufferedReader(new InputStreamReader(in));
Scanner input = new Scanner (System.in);
System.out.print("Enter Your Search: "); // String key="red or yellow";
String key = input.nextLine();
while ((strLine = br.readLine()) != null) {
Pattern p = Pattern.compile(key); // regex pattern to search for
Matcher m = p.matcher(strLine); // src of text to search
boolean b = false;
while(b = m.find()) {
System.out.println( " " + m.group()); // returns index and match
// Print the content on the console
}
}
//Close the input stream
in.close();
}catch (Exception e){//Catch exception if any
System.err.println("Error: " + e.getMessage());
}
}
