How to split string by comma and newline (\n) in Java?

Kopite1905 :

So I have this string : "New York,USA,1000\n" + "City,World,2000\n";

I need to split it first by newline and then by comma, so at the end I get an array of strings that is like this: New York has index 0, USA index 1, 1000 index 2, World index 4 and so on..I tried using String[] newline = string.split("\n") and then declaring a new array of strings called result ( giving it 1000 characters randomly ) and making a for loop like this:

String[] result = new String[1000];
for (String s : newline){
  result=s.split(",");
}

But it doesn't work properly. Any help, please?

public class Test {
    public static void main(String[] args) {
        String string = "New York,USA,1000\n" + "City,World,2000\n";
        String[] newline = string.split("\n");
        String[] result = new String[1000];
        //first loop
        result = newline[0].split(",");
        System.out.println(Arrays.toString(result));
        //second loop
        result = newline[1].split(",");
        System.out.println(Arrays.toString(result));
    }
}
/*
output:
[New York, USA, 1000]
[City, World, 2000]
 */

result would be overrided instead of append.

public class Test {
    public static void main(String[] args) {
        String string = "New York,USA,1000\n" + "City,World,2000\n";
        String[] newline = string.split("\n");
        String[] result = new String[1000];
        int index = 0;
        for (String s : newline) {
            for (String t : s.split(",")) {
                result[index++] = t;
            }
        }
        for (int i = 0; i < index; i++) {
            System.out.print(result[i] + " ");
        }
    }
}
/*
output:
New York USA 1000 City World 2000 
 */
