    Default Splitting

    Very new to java

    Simply, i want to split a user input wherever they have put .,! etc...

    Then add each split to a separate array

    my very basic code...

    ArrayList array = new ArrayList();
    System.out.println("Enter: ");
    BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
    String input = null;
    try{
    input = br.readLine();
    } catch (IOException e){
    System.out.println("Error");
    }

    Have a look here for a simple tokenizing method: StringTokenizer (Java Platform SE 6)

    ...Unless this is an assignment in which you are supposed to create the method yourself? I couldn't tell by your original post.

    You can use the Scanner class to get input, and regex class to split on your input
    Java Code:
    import java.util.Scanner;
    import java.util.regex.*;
    
    public class StringInput {
        public static void main(String[] args){
            Scanner sc = new Scanner ( System.in ) ;
            System.out.println("Enter: ");
            String input = sc.nextLine();
            sc.close();
            Pattern p = Pattern.compile("[!.,]");
            String[] tokens = p.split( input );
            for( String str : tokens){
                System.out.println("->"+str);
            }
        }
    }
