JAVA 判断某个文件中是否包含指定字符串

public class FindStringInTxt {
	String encoding = "UTF-8";
	public static void main(String[] args) throws IOException {
		findStringInFile("C://1.TXT");
	}
	
	public static void findStringInFile(String path) throws IOException{
		File file = new File(path);
        InputStreamReader read = new InputStreamReader(new FileInputStream(file),"UTF-8");//考虑到编码格式
        BufferedReader bufferedReader = new BufferedReader(read);
		String line = null;
		while ((line = bufferedReader.readLine()) != null) {
			if(line.startsWith("#")){
				continue;
			}
			//指定字符串判断处
			if (line.contains("xxyy")) {
				System.out.println(line);
			}
		}
	}
}
