A java Set of floats can be converted to a String in Scala by utilizing toString method of Java in Scala. Here, you need to import Scala’s JavaConversions object in order to make this conversions work.
Now, lets see some examples and then discuss how it works in details.
[3.2, 6.4, 9.6]
Here, the digit after decimal is different for each element of the set and so, the resultant output is arranged in the ascending order of the digit after the decimal.
[2.1, 3.1, 1.1]
Here, the digit after the decimal is same for all the elements of the list so, the resultant output is in same order as stated above.
