  The 9 lines of code of Google

Are you still remembering the then hot debated news about Oracle suing Google allegedly copying a small portion of codes from Oracle's Java in 2010. At that time, Oracle experts estimated that Google owes Oracle between $1.4 billion and $6 billion in damages if liable. But the court thought Oracle was eligible only for statutory damages for that copying, which were not expected to exceed a few hundred thousand dollars. At last, Oracle agreed the zero damage result. Are you curious about whi...

  C vs Java Complete Comparison

Similarities: Java and C have same syntax operators. Difference—thinking Two paradigms: Java: Object oriented language C: Structured language Differences: --Syntax No preprocessor Java does not include a preprocessor and does not define any analogs of the #define, #include, and #ifdef directives. Constant definitions are replaced with static final fields in Java. (See the java.lang.Math.PI field for an example.) Macro definitions are not available in...

  Android create button tutorial

This tutorial assumes that you already have an activity and are using an XML layout. Open the layout XML and add the button element.  Assign an ID with the “@+id” operator.  The + tells Android to generate an ID for this element so that you can reference it in your Java files. This is an example. Your layout and text elements will probably be very different. In this example case, the ID of the button is “close”. <Button android:id="@+id/close" android:lay...

  ByteBuffer in Java

ByteBuffer is introduced in java.nio since Java 1.4. It provides a way of representing raw structured data such as from a file or from network. It enables fast access of underlying data compared to traditional ways like byte[] Prior to Java 1.4, if you want to represent a structured raw data, you need to create a byte[] and then having a set of checks to delimit the byte array to get the expected tokens. There are three ways to create a ByteBuffer: Wrapping an exiting array by calling ByteBuffe...

  The ‘Edge’ in Developing for Android Devices

In today’s times, the consumer is spoiled for choice with the number of options they have with respect to owning mobile device hardware and their operating systems. This diverse availability raises a critical question for both independent developers as well as large app development companies as to which platform to target. Although for larger app development companies, it is possible to simultaneously develop for multiple platforms, it might not be the case for small-scale enterprises. In...

  Some thoughts about Facebook native app

On Techcrunch Disrupt last month, Facebook CEO Mark Zuckerberg's remarks about their mobile app sparked a denunciation against Web App. HTML 5 seems to have become the bottleneck of poor experience of all related mobile applications. From the user perspective, Facebook native iOS App rates from the 1.5 star to four star now; since the introduction of new native app, the user usage is doubled.

  Arrays.equals() vs MessageDigest.isEqual()

Both Arrays.equals() and MessageDigest.isEqual() are used to compare the equality of two arrays. They can be interchangeably in many cases. However, they do have some differences which lead to different use cases in real applications. One difference is that the arrays passed to MessageDigest.isEqual() cannot be null while it's ok for Arrays.equals(). The one major difference between these two methods is that Arrays.equals() is not time-constant while MessageDigest.isEqual() is time-constant. Thi...

  How many bytes a boolean value takes in Java?

Have you ever wondered how many bytes a boolean value takes in Java? One byte, this might be the answer comes out of your mind right away. But is it? Let's dig in more. Per Oracle documentation on boolean value definition, there is below statement: boolean: The boolean data type has only two possible values: true and false. Use this data type for simple flags that track true/false conditions. This data type represents one bit of information, but its "size" isn't something that's precisely defin...
