org.apache.commons.lang3.builder.ToStringBuilder
Assists in implementing {@link Object#toString()} methods.
This class enables a good and consistent toString() to be built for any class or object. This class aims to simplify the process by:
- allowing field names
- handling all types consistently
- handling nulls consistently
- outputting arrays and multi-dimensional arrays
- enabling the detail level to be controlled for Objects and Collections
- handling class hierarchies
To use this class write code as follows:
```
 public class Person { String name; int age; boolean smoker; ... public String toString() { return new ToStringBuilder(this). append("name", name). append("age", age). append("smoker", smoker). toString(); } } 
```
This will produce a toString of the format: Person@7f54[name=Stephen,age=29,smoker=false]

To add the superclass toString, use {@link #appendSuper}. To append the toString from an object that is delegated to (or any other object), use {@link #appendToString}.

Alternatively, there is a method that uses reflection to determine the fields to test. Because these fields are usually private, the method, reflectionToString, uses AccessibleObject.setAccessible to change the visibility of the fields. This will fail under a security manager, unless the appropriate permissions are set up correctly. It is also slower than testing explicitly.

A typical invocation for this method would look like:
```
 public String toString() { return ToStringBuilder.reflectionToString(this); } 
```
You can also use the builder to debug 3rd party objects:
```
 System.out.println("An object: " + ToStringBuilder.reflectionToString(anObject)); 
```
The exact format of the toString is determined by the {@link ToStringStyle} passed into the constructor.
