When you call Arrays.asList it does not return a java.util.ArrayList. It returns a java.util.Arrays$ArrayList which is an immutable list. You cannot add to it and you cannot remove from it. If you want a mutable list built from your array you will have to loop over the array yoursel...
Array is mutable, but fixed length. Which means you can modify items in the Array, but you cannot add / remove item; //Array is fixed length, you cannot add or remove itemval ary: Array<String> = arrayOf("Wan", "Zhen", "Tian") ary[1] = "gg"println(ary.contains("gg"))//tru...

.collect(collectors.tolist()); assert.assertequals(expectedstringlist, outputlist); this approach works well for java 8 and above as the streams api was introduced in java 8. the list produced as output here is a mutable list, which means we can add elements to it. the output list can ...
