We can use it to avoid the conversion of the null values from inside the Iterable: String commaSeparatedStringSkipNulls = Joiner.on(",")ĪssertThat(commaSeparatedStringSkipNulls).isEqualTo("ONE,TWO,THREE") Īnother option is to use useForNull(), which takes a String value as a parameter to substitute the null values inside the Iterable to convert: String commaSeparatedStringUseForNull = Joiner.on(",")ĪssertThat(commaSeparatedStringUseForNull).isEqualTo("ONE, ,TWO, ,THREE") 6.If you are willing to change your datatype a bit, you could use a Map. Given that, we can use other methods between the on() and join(), and one of these is the skipNulls() method. Let’s take another list containing some null values for the next example: List arraysAsListWithNull = Arrays.asList("ONE", null, "TWO", null, "THREE") The first method is on(), which takes as a delimiter parameter a String, and then the second method is the join() method which takes as a parameter the Iterable having the values to convert: String commaSeparatedString = Joiner.on(",")ĪssertThat(commaSeparatedString).isEqualTo("ONE,TWO,THREE")
