In one sentence, describe what the following article is about: " In your text editor, create a new file and save it as "HelloWorld.java". HelloWorld is your class name and you will need your class name to be the same name as your file. The main method public static void main(String[] args) is the method that will be executed when the programming is running. This main method will have the same method declaration in every Java program.   public class HelloWorld {     public static void main(String[] args) {     } } "   System.out.println("Hello World.");    Let's look at the components of this line:   System tells the system to do something.  out tells the system that we are going to do some output stuff.  println stands for "print line," so we are telling the system to print a line in the output. The parentheses around ("Hello World.") means that the method System.out.println() takes in a parameter, which, in this case, is the String "Hello World."    Note that there are some rules in Java that we have to adhere to:  You must always add a semicolon at the end of every line. Java is case sensitive, so you must write method names, variable names, and class names in the correct case or you will get an error. Blocks of code specific to a certain method or loop are encased between curly brackets. Your final Hello World program should look like the following:  public class HelloWorld {     public static void main(String[] args) {         System.out.println("Hello World.");     } } Navigate to the folder where you saved HelloWorld.java and type in javac HelloWorld.java. This tells the Java compiler that you want to compile HelloWorld.java. If there are errors, the compiler will tell you what you did wrong. Otherwise, you shouldn't see any messages from the compiler. If you look at the directory where you have HelloWorld.java now, you should see HelloWorld.class. This the the file that Java will use to run your program. Finally, we get to run our program! In command prompt or terminal, type in java HelloWorld. This tells Java that you want to run the class HelloWorld. You should see "Hello World." show up in your console.
Summary: We will first create a program that prints "Hello World. Declare your class and your main method. Write the line of code that will print out "Hello World. Put it all together. Save your file and open up command prompt or terminal to compile the program. Run the program. Congratulations, you have made your first Java program!

In one sentence, describe what the following article is about: A decreased appetite is a common sign of digestive problems in rabbits. Be aware that a reduced appetite can be hard to notice at first—your rabbit may be sick for several days before you realize he’s eating less. Anorexia in rabbits can lead to serious medical problems, so do not delay in getting treatment for your rabbit if you notice he is not eating. Your rabbit may be eating less because he is unable to eat, not because he doesn’t want to. For example, dental disease may make it difficult for your rabbit to chew his food properly. A healthy rabbit produces two types of fecal pellets: a hard pellet made of indigestible fiber, and a soft pellet (‘cecotrope’). Rabbits eat the cecotropes for additional nutrients. For some digestive problems, such as gastrointestinal (GI) stasis, rabbits will produce fewer pellets, or none at all.  Digestive problems due to a bacteria or virus can cause diarrhea. Inflammation of the intestine can produce mucus-covered pellets.  Consider taking a picture of the feces so you can show your veterinarian what the feces look like. As with a decreased appetite, your rabbit’s demeanor and behavior may change when he has digestive upset. For example, he may become more lethargic and prefer to be left alone. Your rabbit may also lie awkwardly on his side or remain in a sitting position to decrease pressure on his belly.  Your rabbit may develop a hunched posture and start grinding his teeth because of the abdominal pain.  Your rabbit may even press his stomach against the floor because of the pain. This occurs if your rabbit has gas. If your rabbit will let you, gently touch his belly. His belly may feel like dough, which indicates gas buildup. Gas accumulation may also make the belly feel very hard. With some digestive problems, such as GI stasis, harmful bacteria can outnumber good bacteria in the gut. These harmful bacteria can release gas. The digestive system will make sounds (‘gut sounds’) as it is processing food and moving it along through the system. These sounds will be abnormal or completely absent if your rabbit has a digestive problem. For example, if your rabbit has gas, his belly will make gurgling noises. With GI stasis, gut sounds are abnormally frequent early on, then decrease or stop completely as the condition worsens.
Summary: Observe changes in your rabbit’s appetite. Monitor your rabbit’s production of fecal pellets. Look for changes in your rabbit’s behavior. Touch your rabbit’s belly. Listen to the sounds of your rabbit’s belly.

In one sentence, describe what the following article is about: A strong social media presence is key for successful fundraising. Get on Facebook, Twitter, Foursquare, and other social media outlets.  Ask a social media savvy friend to help if you're not familiar with these outlets yourself. A strong Facebook fan page, as well as a Twitter presence, can be a great means to spread the word of an event to many people at once. Reach out to the right people. Blindly inviting your entire Facebook friend's list is a big no-no. You're likely to annoy people who do not live in the area or who are not interested in the cause. Stick to inviting people who you know have similar views and live near enough to attend. People are more likely to donate if they know where their money is going. Know exactly where your money will be going and be upfront with people about this. If people know that, say, $5 buys one vaccination for a child in need in a third world country they'll be motivated to give. As you'll likely have to go through some auditing process for tax purposes, keep thorough records. Keep records of who donated, how much they donated, and what the money went towards. The key to getting people to donate is genuinely believing in your cause yourself. Know as much as you can about your cause so you sincerely believe it's worth it.  If you know a lot about your cause, you're likely to feel more passionate about it. When you send out an e-mail or letter asking for donations, you'll sound more convicted. This can motivate people to donate.  People enjoy contributing to worthy causes. It makes them feel positive about themselves and involved in their community. The stronger you believe in your cause, the more others will want to help you out. The easier it is for passersby to donate to your cause, the more money you'll be likely to raise. Make it easy for potential donors to make a contribution. If you have a website set up to collect donations, ensure that it is easy to navigate. If you've set up an account at the local bank, make sure the instructions for making a deposit are clear. Low minimums for donations are more likely to make people feel like they can afford it. Each person that donates should receive a message from you or your organization, thanking them for their contribution and outlining what the money will be used for. Make the donor feel good about the money that they contributed. Thanking your donor also makes it easier to get in contact again when you run another fundraiser.  For large organizations, its expected that a thank-you message be sent out within 48 hours of the donation. For personal fundraisers, you should be working to thank people as soon as they make their donation, and again after the fundraiser is complete.
Summary:
Build a strong social media presence. Itemize expenses. Keep records. Believe in your cause. Make donating as easy as possible. Thank each of your donors.
