How to split a a string in java by multiple delimiters with padding spaces?

Question

We tried many forms of regular expressions in this answer. Our input string is

"string1 & string2 / string3"

and we would like to split it into the string into

{"string1","string2","string3"}

on the delimiters & and / (with one space of padding for each).

How can we construct a regular expression to do this using string.split(" [/&] ")?

Answer 1

Didn't got ur question correctly, what you have mentioned is perfectly ok.

And if you want this :: {"string1","string2","string3"}

simply do : System.out.println( "{\"" + s.replaceAll( " [/&] ", "\",\"") + "\"}" );

Answer 2

Try the below one.

String[] result = string.split(" & | / ");

Hopes this helps.

Answer 3

Try this:

String[] split = s.split("[&//] ");

Answer 4

    for (String part : "string1 & string2 / string3".split(" [/|&] ")) {
        System.out.println(part);
    }

So what you're interested in is the .split(" [/|&] ") part

Answer 5

Just try with

String input = "string1 & string2 / string3";
boolean first = true;

StringBuilder sb = new StringBuilder("{\"");

for (String part : input.split(" [&/] ")) {
    if (!first) {
        sb.append("\",\"");
    }
    sb.append(part);
    first = false;
}

String output = sb.append("\"}").toString();

Output:

{"string1","string2","string3"}

Answer 6

Your code runs just fine.

import java.lang.*;

public class StringDemo {

  public static void main(String[] args) {

    String str = "string1 & string2 / string3";
    String delimiters = " [/&] ";

    // analyzing the string
    String[] tokensVal = str.split(delimiters);

    // prints the number of tokens
    System.out.println("Count of tokens = " + tokensVal.length);

    for(String token : tokensVal) {
       System.out.println("#" + token + "#");
    }
  }
}
