Mothers Who Abuse essays

Mothers Who Abuse essays Mothers can abuse children in many ways. The main form of abuse most people think of is physical. Some other important forms are related to alcohol, tobacco, and cocaine use. There are many effects resulting from the use of alcohol, tobacco, and cocaine during pregnancy. One form of abuse a fetus can experience is the use of alcohol by the mother. A direct result from alcohol use by some mothers is fetal alcohol syndrome. Fetal alcohol syndrome is a serious health problem that tragically affects its victims and their families, but that is completely preventable. Causing a child to suffer from fetal alcohol syndrome is really nothing short of child abuse and it lasts for life. Babies born with fetal alcohol syndrome tend to weigh less and be shorter than normal. They usually suffer from smaller heads, deformed facial features, abnormal joints and limbs, poor coordination, problems with learning, and short memories. Victims of fetal alcohol syndrome often experience mental health problems, a disrupted school experience, inappropriate sexual behavior, trouble with the law, alcohol and drug problems, difficulty caring for themselves and their children, and homelessness. Another form of abuse a fetus can experience is the use of tobacco by the mother. Smoking during pregnancy can cause different problems than alcohol. The main problem with tobacco use during pregnancy is the dirtiness of tobacco. It contains about four thousand different chemicals, including heavy metals, tars, gases, and even radioactive materials. Two of the best known chemicals in cigarette smoke are nicotine and carbon monoxide. Both reduce oxygen flow to the fetus, while nicotine speeds up heartbeat and increases blood pressure in the fetus. There are many risks of smoking during pregnancy. One risk is delayed growth. The more a woman smokes, the less her baby grows. Twice as many babies weighing less than five pounds are born to smokers...

How to Use Comments in Java Code

How to Use Comments in Java Code Java comments are notes in a Java code file that are ignored by the compiler and runtime engine. They are used to annotate the code in order to clarify its design and purpose. You can add an unlimited number of comments to a Java file, but there are some best practices to follow when using comments. Generally, code comments are implementation comments that explain the source code, such as descriptions of classes, interfaces, methods, and fields. These are usually a couple of lines written above or beside Java code to clarify what it does. Another type of Java comment is a Javadoc comment. Javadoc comments differ slightly in syntax from implementation comments and are used by the program javadoc.exe to generate Java HTML documentation. Why Use Java Comments? Its good practice to get into the habit of putting Java comments into your source code to enhance its readability and clarity for yourself and other programmers. It isnt always instantly clear what a section  of Java code is performing. A few explanatory lines can drastically reduce the amount of time it takes to understand the code. Do They Affect How the Program Runs? Implementation comments in Java code are only there for humans to read. Java compilers dont care about them and when compiling the program, they just skip over them. The size and efficiency of your compiled program will not be affected by the number of comments in your source code. Implementation Comments Implementation comments come in two different formats: Line Comments: For a one line comment, type // and follow the two forward slashes with your comment. For example: // this is a single line comment int guessNumber (int) (Math.random() * 10); When the compiler comes across the two forward slashes, it knows that everything to the right of them is to be considered as a comment. This is useful when debugging a piece of code. Just add a comment from a line of code you are debugging, and the compiler wont see it: // this is a single line comment // int guessNumber (int) (Math.random() * 10); You can also use the two forward slashes to make an end of line comment: // this is a single line comment int guessNumber (int) (Math.random() * 10); // An end of line comment Block Comments: To start a block comment, type /*. Everything between the forward slash and asterisk, even if its on a different line, is treated as a  comment until the characters */ end the comment. For example: /* this is a block comment */ /* so is this */ Javadoc Comments Use special Javadoc comments to document your Java API. Javadoc is a tool included with the JDK that generates HTML documentation from comments in source code. A Javadoc comment in  .java  source files is enclosed in start and end syntax like so:  /**  and  */. Each comment within these is prefaced with a  *.   Place these comments directly above the method, class, constructor or any other Java element that you want to document. For example: // myClass.java/** * Make this a summary sentence describing your class.* Heres another line. */public class ​myClass{...} Javadoc incorporates various tags that control how the documentation is generated. For example, the  param  tag defines parameters to a method: /** main method * param args String[] */​ public static void main(String[] args) ​{ ​ System.out.println(Hello World!);​ } Many other tags are available in Javadoc, and it also supports HTML tags to help control the output. See your Java documentation for more detail. Tips for Using Comments Dont over comment. Every line of your program does not need to be explained. If your program flows logically and nothing unexpected occurs, dont feel the need to add a comment.Indent your comments. If the line of code you are commenting is indented, make sure your comment matches the indentation.Keep comments relevant. Some programmers are excellent at modifying code, but for some reason forget to update the comments. If a comment no longer applies, then either modify or remove it.Dont nest block comments. The following will result in a compiler error: /* this is /* This block comment finishes the first comment */ a block comment */
