Java String Format Examples
Have you tried to read and understand Java’s String format documentation? I have and found it nearly impenetrable. While it does include all the information, the organization leaves something to be desired. This guide is an attempt to bring some clarity and ease the usage of string formatting in Java.
Photobioreactor in general A bioreactor is an installation for the production of microorganisms outside their natural but inside an artificial environment. The prefix “photo” particularly describes the bio-reactor's property to cultivate phototrophic microorganisms, or organisms which grow on by utilizing light energy. These organisms use the process of photosynthesis to build their own biomass from light and CO2. Members of this group are Plants, Mosses, Macroalgae, Microalgae, Cyanobacteria and Purple Bacteria. Key objective of a photobioreactor, or PBR, is the controlled supply of specific environmental conditions for respective species.
ArrayList in Java
ArrayList is a part of collection framework and is present in java.util package. It provides us with dynamic arrays in Java. Though, it may be slower than standard arrays but can be helpful in programs where lots of manipulation in the array is needed. This class is found in java.util package. Example: The following implementation demonstrates how to create and use an ArrayList. Output:
Java version history
After the Java 7 release, Oracle promised to go back to a 2 year release cycle. However, in 2013, Oracle announced that they would delay Java 8 by one year, in order to improve the Java security model. JDK Alpha and Beta (1995) Alpha and Beta Java public releases had highly unstable APIs and ABIs. The supplied Java web browser was named WebRunner.
The albedo of several types of roofs Reflective surfaces are artificially-altered surfaces that can deliver high solar reflectance (the ability to reflect the visible, infrared and ultraviolet wavelengths of the sun, reducing heat transfer to the surface) and high thermal emittance (the ability to radiate absorbed, or non-reflected solar energy). Reflective surfaces are a form of geoengineering. The most well-known type of reflective surface is the cool roof.
40 Java Inheritance Practice Coding Questions
40 Java Inheritance Practice Coding Questions : 1) Tinku has written the code like below. But, it is showing compile time error. Can you identify what mistake he has done? Answer : In Java, a class can not extend more than one class.
Java SE EOL Policy (Oracle Java SE Support Roadmap)
Oracle provides this updated roadmap for Oracle Java SE products (Oracle Java SE Advanced, Oracle Java SE Advanced Desktop and Oracle Java SE Suite) to help customers understand the maintenance and support options available. Starting September 2017, Oracle has moved to a "Long Term Support" (LTS) model for Oracle Java SE products. This means that LTS versions, offering Premier and Sustaining Support, will be targeted for release every three years. In addition, feature releases will be targeted for every six months along with quarterly maintenance/security updates.
Inheritance - Learn Java - Free Interactive Java Tutorial
In Java, the term inheritance refers to the adoption of all non-private properties and methods of one class (superclass) by another class (subclass). Inheritance is a way to make a copy of an existing class as the starting point for another. In addition to the term subclass, inherited classes are also called derived classes. At this point, it may be helpful to distinguish inheritance from interfaces. Interfaces define only the structure of the class members while inherited classes include the actual code of the superclass. Additionally, inheritance (more accurately, the definition of a subclass) uses the extends keyword in the subclass declaration.
festselenium - fest + selenium for applet automation testing
In-browser applet testing can now be accomplished using festselenium in conjunction with Selenium RC. The purpose of this project is provide a java driver to commnuicate with Selenium then drive the fest-swing to do applet automation acceptance testing. This project relies heavily on the GetEval provided by selenium.
Methods in Java
A method is a collection of statements that perform some specific task and return the result to the caller. A method can perform some specific task without returning anything. Methods allow us to reuse the code without retyping the code. In Java, every method must be part of some class which is different from languages like C, C++, and Python.
JSP Quick Guide
What is JavaServer Pages? JavaServer Pages (JSP) is a technology for developing web pages that support dynamic content which helps developers insert java code in HTML pages by making use of special JSP tags, most of which start with <% and end with %>. A JavaServer Pages component is a type of Java servlet that is designed to fulfill the role of a user interface for a Java web application. Web developers write JSPs as text files that combine HTML or XHTML code, XML elements, and embedded JSP actions and commands.
1.7 Java EE 7 APIs - Java Platform, Enterprise Edition: The Java EE Tutorial (Release 7)
Figure 1-6 shows the relationships among the Java EE containers. Figure 1-7 shows the availability of the Java EE 7 APIs in the web container. Figure 1-8 shows the availability of the Java EE 7 APIs in the EJB container.
Java Platform Debugger Architecture
Java Debugger Interface (JDI) - defines a high-level Java language interface that developers can easily use to write remote debugger application tools.Java Virtual Machine Tools Interface (JVMTI), a native interface that helps to inspect the state and to control the execution of applications running in the Java Virtual Machine (JVM).Java Virtual Machine Debug Interface (JVMDI)- JVMDI was deprecated in J2SE 5.0 in favor of JVM TI, and was removed in Java SE 6.Java Debug Wire Protocol (JDWP) - defines communication between debuggee (a Java application) and debugger processes.
