JAVA的try catch用法错误

//filename: A.java
import java.util.Scanner;

public class A {
    public static void main(String[] args) {
        String line;
        Scanner reader;
        
        // try 是一个关键字 不是方法 所以要去掉括号
        try {
            while (reader.hasNext()) {
                line = reader.nextLine();
                System.out.println("Read a line: " 
                    + line);
                if (line.endsWith("exit") 
                        || line.endsWith("quit")) {
                    break;
                }
            }
        } catch (Exception e) {
            System.out.pritnln(e.getMessage());
            e.printStackTrace();
        }
    }
}
