通过两件事拆分字符串？

Question

I have the following code:

import java.util.Scanner;
public class Chapter11_ProjectPinochle {
public static void main(String[]args) {
    Scanner sc=new Scanner(System.in);
    String a;
    System.out.println("Type in your pinochle deals: ");
    a=sc.nextLine();
    sc.close();
    String[] deals=a.split(""); 
}
}

I need to split the String I named "a" into a 16 spaced array. But the problem with the splitting is that the input is something like this: ATKQQJ,AKQQ,KQQJN,A . I need to split this into 16 parts and save it to an array I named "deals." I've tried String[] deals=a.split("" && ","); but apparently that isn't valid. I've also tried to split String a into 2 separate arrays and then put them together, but I realized I didn't know how. I want the output to be ["A","T","K","Q","Q","J","A","K","Q","Q","K","Q","Q","J","N","A"] when the input is: ATKQQJ,AKQQ,KQQJN,A . How should I accomplish this?

Answer 1

//Split it out into individual characters
System.out.println(Arrays.toString("ATKQQJ,AKQQ,KQQJN,A".replace(",", "").toCharArray()));
//Split it into strings of a single character
System.out.println(Arrays.toString("ATKQQJ,AKQQ,KQQJN,A".replace(",", "").split("")));

Answer 2

Here you go:

    String a = "ATKQQJ,AKQQ,KQQJN,A";

    // Split the string into comma-separated parts
    String[] parts = a.split(",");

    //Join those parts into a single string
    String whole = String.join("",parts);

    //Finally, split it up into individual letters
    String[] letters = whole.split("");

Could have also generated whole by removing the commas from a .

Try this code

import java.util.Scanner;

public class Chapter11_ProjectPinochle {
    public static void main(String[]args) {
        Scanner sc = new Scanner(System.in);
        String a,b="";
        System.out.println("Type in your pinochle deals: ");
        a = sc.nextLine();
        sc.close();
        String[] temp = a.split(",");
        for (int i=0; i<temp.length; i++){
            for (int j=0; j<temp[i].length(); j++){
                b+=temp[i].charAt(j);
            }
        }
        char[] deals=new char[b.length()];
        for (int i=0; i<b.length(); i++){
            deals[i]=b.charAt(i);
        }

    }

}
