It can be best explained with an example. Arrays.asList() returns its own implementation of a List based on the implementation of the array parameter, which may not be an ArrayList. I need to pass an arraylist of integer type to method calculate() and I can not make paretoSet an integer arraylist as it creates problem in other methods of the program. Each Line is then created as an ArrayList of Strings, with each String being a word on that line (I used the String Split at spaces (" ") to perform this).

I tried to cast an arraylist at index i in paretoSet to integer type and then added it to toPass but this casting is not allowed!!! check my blog I thought it worked similar to the asList in that it simply made one data set into another type (So, list would convert "to an Array").

Other points of interest: your variable should be camel case: pareToSet auto-boxing means the cast in your for loop has been unnecessary since JDK5 Paretoset has been declared with a raw

Since a string array is passed into Arrays.asList in both cases, shouldn't both snippets produce an exception or not produce an exception? More broadly, you have a classic code style problem: You should be referring to abstract interfaces (ie List), not concrete implementations (ie ArrayList).
