The “toString()” method can be used to print a list in Java. This method prints the specified list elements directly using their references. Example First, we will create a list of String type named “gadgetList” using the Java collection ArrayList: List<String>gadgetList=newArrayList<String...

Starting from Java 8, we can use theString.join()method to concatenate the elements of a Set into a single string. This method takes a delimiter and an Iterable, which the Set implements. Here’s an example: importjava.util.Set;publicclassSetToStringExample{publicstaticvoidmain(String[]args...
