Java用逗号或0（零）后跟空格分隔字符串

Question

If I have a string, eg

 s = "david,marko,rita,0 megan,0 vivian,law";

I need split this string into

david
marko
rita
megan
vivian
law

I am trying with

String arr[] = s.split("[,\\s]");

but didn´t work. Any suggestions?

Answer 1

You could use this expression:

String arr[] = s.split(",0?\\s*");

Or maybe even:

String arr[] = s.split("[,0\\s]+");

Which one you want is unclear from the example.

Answer 2

Your regex is : "(,0 |,)"

So try this code :

public static void main(String[] args){
        String s = "david,marko,rita,0 megan,0 vivian,law";
        String[] ss = s.split("(,0 |,)");
        for (int i = 0; i < ss.length; i++) {
            String string = ss[i];
            System.out.println(string);
        }
    }

Answer 3

Just an advice Rather then splitting with multiple values try this

import java.util.*;
class test {
  public static void main(String[] args) {
    String s = "david,marko,rita,0 megan,0 vivian,law";
    System.out.println(Arrays.toString(s.replace("0","").replace(" ","").split(",")));
  }
}

Answer 4

You can try this:

public class SplitTest {

    public static void main(String[] args) {
        String inputString = "david,marko,rita,0 megan,0 vivian,law";
        String splits[] = inputString.split(",0?\\s*");
        for (String split : splits) {
            System.out.println(split);
        }
    }
}

Answer 5

String[] arr = s.split(",(0\\s+)*");

The regex splits on a comma followed optionally by a 0 and one or more spaces.

      public static void main(String[] args) {
         String s = "da0vid,marko,rita,0 megan,0 vivian,law";
         String[] arr = s.split(",(0\\s+)*");
         for (int i = 0; i < arr.length; i++)
           System.out.println("'"+arr[i]+"'");
      }

=>
'da0vid'
'marko'
'rita'
'megan'
'vivian'
'law'
