This article gives 5 reasons to upgrade to Java 2 Platform, Standard Edition (J2SE Platform) 5.0. Each reason is validated by a large amount of data and references to the fact that upgrading to version 5.0 will significantly reduce development and operational costs. J2SE 5.0 (code-named Project Tiger) was released at the end of September 2004. It is one of the major updates of the Java platform over the years. The Java Community cheers for its new fe

Java 8 new features-5 built-in functional interfaces, new features-5 In the previous blog Lambda expressions, I mentioned functional interfaces provided by Java 8. In this article, we will introduce the four most basic functional interfaces of Java 8. For method reference, an interface must be defined strictly. No matter how we operate, there are actually only four possible interfaces. Java 8 provides a fun

Given the two files a and B, each of them stores 5 billion URLs. Each url occupies 64 bytes and the memory limit is 4 GB. How can we find the common URLs of files a and B ?, 5 billion 4g It can be estimated that the size of each file is 5G * 64 = 300G, much larger than 4G. Therefore, it is impossible to fully load it into the memory for processing. Consider a divide-and-conquer approach.Traverse file a, ob
