How to join strings with Delimiter in Java

To join strings with delimiter we can use the String.joiner() method in Java.

Here is an example that joins the given strings with a delimiter -.

public class Main
{
      public static void main(String[] args) {
        String all = String.join("-","01","02","2020");
        System.out.println(all);
   }
}

Output:

01-02-2020

Similarly, in Java 8 we can also use StringJoiner class.

import java.util.StringJoiner;

public class Main
{
	public static void main(String[] args) {
	    StringJoiner all = new StringJoiner("-");
        all.add("1").add("02").add("2020");
		System.out.println(all); // 01-02-2020
	}
}
