Webproblem on calculating Big O complexity. i have this function on which i have to calculate the time complexity with the Big O notation: public void print (ArrayList … WebGetting the keyset is O(1) and cheap. This is because HashMap.keyset() returns the actual KeySet object associated with the HashMap.. The returned Set is not a copy of the keys, but a wrapper for the actual HashMap's state.Indeed, if you update the set you can actually change the HashMap's state; e.g. calling clear() on the set will clear the HashMap!

Having 4 years of experience in Quantitative Data Analysis, Time Series Forecasting, Visualization, Modeling ... Usually, when we talk about time complexity, we refer to Big-O notation. Simply put, the notation describes how the time to perform the algorithm grows with the input size. Useful write-ups are available to learn more about Big-O notation theory and practical Java examples. See more In this tutorial, we'll talk about the performance of different collections from the Java Collection API.
