Implementing PayPal Payments: A Practical Guide and Pain Points

I’m trying to solve all the Advent of Code puzzles in this video series.

We talk about the different collection structures in Java and how to measure their performance and memory footprint Simple example of performance testing for collection types in java: package org.ea.debugger; import java.lang.management.ManagementFactory; import java.util.*; import java.util.function.IntConsumer; public class CollectionTest { public static void sleep() { try { Thread.sleep(3000); } catch (Exception e) { e.printStackTrace(); }…

We look at what will come in the next release of java. Java 14, this release will wrap up development for the long time support release.

We look at connecting up a native library, native source to our Android application.
