How to join Strings with a delimeter using the Java join() method

In this video, we will have a look at the Java join() method, which is used to join given Strings using a delimiter and returns a concatenated String. Let’s use an example to see exactly how this method works String str1 = “I”; String str2 = “love”; String str3 = “programming”; String str4 = String.join(“/” , str1 , str2 , str3);

String str = String.join(“/” , “I” , “love” , “programming”); Here the first parameter “/” is called a delimiter and it is used to join the remaining strings passed as parameter System.out.println(str); If we run this program, we will get : I/love/programming

This method can also be used to join list elements using a delimiter Here is an example List list String = Arrays.asList("Paris", "Vancouver", "Berlin", "Washington");

String cities = String.join(" | ", list);

System.out.println(cities);

This program will return : Paris|Vancouver|Berlin|Washington
