Java - String Splitting and Joining

Introduction

split() method to split a string into multiple strings using a delimiter.

split() method returns an array of String.

public class Main {
  public static void main(String[] args) {
    String str = "AL,FL,NY,CA,GA";

    // Split str using a comma as the delimiter
    String[] parts = str.split(",");

    // Print the the string and its parts
    System.out.println(str);

    for (String part : parts) {
      System.out.println(part);
    }

  }
}

join() method to the String class that joins multiple strings into one string. It is overloaded.

String join(CharSequence delimiter, CharSequence... elements)
String join(CharSequence delimiter, Iterable<? extends CharSequence> elements)

The following code uses the first version to join some strings:

Demo

public class Main {
  public static void main(String[] args) {
    // Join some strings using a comma as the delimiter
    String str = String.join(",", "AL", "FL", "NY", "CA", "GA");
    System.out.println(str);//from www  .  j  ava 2  s.co  m

  }
}
