Conventions

In this book, you will find a number of styles of text that distinguish between different kinds of information. Here are some examples of these styles, and an explanation of their meaning.

Code words in text are shown as follows: "We can include other contexts through the use of the include directive."

A block of code will be set as follows:

package org.springaop.target;
public class ExceptionTarget {
public void errorMethod() throws Exception {
throw new Exception("Fake exception");
}
public void otherErrorMethod() throws IllegalArgumentException {
throw new NullPointerException("Other Fake exception");
}
}

When we wish to draw your attention to a particular part of a code block, the relevant lines or items will be made bold:

package java.lang.reflect;
public interface InvocationHandler {
public Object invoke(Object proxy, Method method, Object[] args)
throws Throwable;
}

Any command-line input and output is written as follows:

java -javaagent:<path_on_your_machine>/spring-framework-X.X/lib/aspectj/aspectjweaver.jar

<package>.<yourclass>.Main

New terms and important words are introduced in a bold-type font. Words that you see on the screen, in menus or dialog boxes for example, appear in our text like this: "clicking the Next button moves you to the next screen".
