Convert Comma-Separated String to List in Java [3 ways]

In this post, I will be sharing how to convert comma-separated String to List in Java with examples. There are 3 ways to achieve our goal of converting comma-separated String to List:

1. Using Java 8 Stream API

2. Using String's split() and Arrays asList() method

3. Using Pattern class

Let's dive deep into the topic:

Convert Comma-Separated String to List in Java

1. Using Java 8 Stream API

We can convert comma-separated String to List using the Collectors.toList() method as shown below in the example:

import java.util.List;
import java.util.stream.*;

public class StringToListOne {
    public static void main(String args[]) {
        String givenString = "Alive, is, Awesome";
        List<String> result = Stream.of(givenString.trim().split(",")).collect(Collectors.toList());
        System.out.println(result);
    }
}

Output:
[Alive, is, Awesome]

2. Using String's split() and Arrays asList() method

Using the String class split() method and Arrays.asList() method we can convert comma-separated string to the List as shown in the below example.

import java.util.List;
import java.util.Arrays;

public class StringToListTwo {
    public static void main(String args[]) {
        String givenString = "Be, in, Present";
        String[] arr = givenString.split(",");
        List<String> list = Arrays.asList(arr);
        System.out.println(list);
    }
}

Output:
[Be, in, Present]

3. Using Pattern class

Using Pattern class also we can convert comma-separated String to the List<String> as shown in the example below:

import java.util.List;
import java.util.stream.*;
import java.util.regex.Pattern;

public class StringToListThree {
    public static void main(String args[]) {
        String givenString = "Love, Yourself";
        List<String> result = Pattern.compile("\\s*,\\s*").splitAsStream(givenString.trim()).collect(Collectors.toList());
        System.out.println(result);
    }
}

Output:
[Love, Yourself]
