带有特殊字符和空格的正则表达式模式问题

Question

I'm trying to extract only the letters using the split method and I'm not getting the expected results. Here's my code

    Scanner myInput = new Scanner(System.in);
    System.out.println("Enter greeting: ");
    String greeting = myInput.nextLine().toLowerCase();
    String[] myGreeting = greeting.split("(.[^a-z])*");
    for(String stry: myGreeting){
        System.out.println(stry);
    }

My output looks like:

Enter greeting: 
Hello!! my Man
h
e
l
l

m

m
a
n

Answer 1

Your regular expression is incorrect, it seems you want the following instead ...

String[] myGreeting = greeting.split("[^a-z]+");
