Concatenate Strings Using String Joiner
Java 8 has added a new class called StringJoiner. This concatenates Strings using a delimiter as well as adds a prefix and suffix to the concatenated String. Performance-wise, it is similar to StringBuffer.append, but it has the added advantage that it automatically adds a delimiter, prefix and suffix. The following code demonstrates how the StringJoiner class can be used to...
Concatenate Strings Using String.join() for Collections
There is an overloaded version of the String.join method that accepts as parameter an Iterable implementation. Since all Collection classes implement the Iterable interface, this method can be used to concatenate all the elements in a Collection. The following code demonstrates this: This code creates a List of String values and passes this List to the String.join method with a...

The findElement method is used when you want to deal with one HTML element on a website. On the other hand, the findElements method is used when you want to deal with more than one...
Concatenate Strings Using String.join()
Java 8 has added a static join method to the String class. This concatenates Strings using a delimiter. Performance wise, it is similar to StringBuffer.append, but it has the added advantage that it automatically adds a delimiter. As before, this code creates string1 and string2. It invokes the join method with these Strings and specifies space (“ “) as...
Concatenate Strings Using StringBuilder.append()
In addition to String, Java has the java.lang.StringBuffer and java.lang.StringBuilder classes. These can also be used to concatenate Strings. The advantage of these classes is that both these classes are mutable, so using them does not result in the creation of new String objects. So StringBuffer and StringBuilder have a better performance as compared to the + operator...
