I want to join a String[]
with a glue string. Is there a function for this?

Starting from Java8 it is possible to use String.join()
.
String.join(", ", new String[]{"Hello", "World", "!"})
Generates:
Hello, World, !
Otherwise, Apache Commons Lang has a StringUtils
class which has a join
function which will join arrays together to make a String
.
For example:
StringUtils.join(new String[] {"Hello", "World", "!"}, ", ")
Generates the following String
:
Hello, World, !
