Splitting a String by two things?
问题
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(",");String concatenatedDeals = String.join("", deals);String[] finalDeals = concatenatedDeals.split("");}}
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(",");String concatenatedDeals = String.join("", deals);String[] finalDeals = concatenatedDeals.split("");// At this point, finalDeals will contain the desired output.// You can print it to verify.System.out.print("[");for (int i = 0; i < finalDeals.length; i++) {System.out.print("\"" + finalDeals[i] + "\"");if (i < finalDeals.length - 1) {System.out.print(",");}}System.out.println("]");}}

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?

// 将其拆分为单个字符System.out.println(Arrays.toString("ATKQQJ,AKQQ,KQQJN,A".replace(",", "").toCharArray()));// 将其拆分为单个字符的字符串System.out.println(Arrays.toString("ATKQQJ,AKQQ,KQQJN,A".replace(",", "").split("")));
英文:
//Split it out into individual charactersSystem.out.println(Arrays.toString("ATKQQJ,AKQQ,KQQJN,A".replace(",", "").toCharArray()));//Split it into strings of a single characterSystem.out.println(Arrays.toString("ATKQQJ,AKQQ,KQQJN,A".replace(",", "").split("")));

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);}}}
英文:
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);}}}

这里是您要的内容：
String a = "ATKQQJ,AKQQ,KQQJN";// 将字符串按逗号分隔成部分String[] parts = a.split(",");// 将这些部分合并为一个单独的字符串String whole = String.join("", parts);// 最后，将其分割为单个字母String[] letters = whole.split("");
也可以通过从 a 中删除逗号来生成 whole。
英文:
Here you go:
String a = "ATKQQJ,AKQQ,KQQJN,A";// Split the string into comma-separated partsString[] parts = a.split(",");//Join those parts into a single stringString whole = String.join("",parts);//Finally, split it up into individual lettersString[] letters = whole.split("");
Could have also generated whole by removing the commas from a.
