The Reflection API represents or reflects the classes, interfaces, and objects in the Java virtual machine. (JVM¹).

• Arrays
• Examining Classes
• Manipulating Objects

• array2.java creates a 10-long array of Strings and sets location 5 in the array to a string value. The value is retrieved and displayed. For supporting information see Using Java Reflection.
  
  
• SampleArray.java prints the names of the arrays encapsulated in an object. For supporting information see The Java Tutorial Continued: Reflection.
  
  
• SampleComponent.java prints out the class name of each array's component type. For supporting information see The Java Tutorial Continued: Reflection.
  
  
• SampleCreateArray.java creates a copy of an array that is twice the size of the original array. For supporting information see The Java Tutorial Continued: Reflection
  
  
• SampleGetArray.java uses the set and get methods to copy the contents of one array to another. For supporting information see The Java Tutorial Continued: Reflection.
  
  
• KeyPad.java works with SampleComponent.java. For supporting information see The Java Tutorial Continued: Reflection.
  
  

• constructor1.java determines which constructors are defined in a given class. For supporting information see Using Java Reflection.
  
  
• find1.java determines which data fields are defined in a given class. For supporting information see Using Java Reflection.
  
  
• instance1.java checks to see which objects are instances of a given class. For supporting information see Using Java Reflection.
  
  
• method1.java determines which methods are defined in a given class. For supporting information see Using Java Reflection.
  
  
• SampleCheckInterface.java checks two class objects to find out whether each represents a class or an interface. For supporting information see The Java Tutorial Continued: Reflection.
  
  
• SampleConstructor.java prints out the parameter types for each constructor in a class. For supporting information see The Java Tutorial Continued: Reflection.
  
  
• SampleField.java prints the names and types of fields belonging to a class. For supporting information see The Java Tutorial Continued: Reflection.
  
  
• SampleInterface.java prints the interfaces implemented by a class. For supporting information see The Java Tutorial Continued: Reflection.
  
  
• SampleMethod.java prints the name, return type, and parameter types of every public method in a class. For supporting information see The Java Tutorial Continued: Reflection.
  
  
• SampleModifier.java identities the modifiers of the String class. For supporting information see The Java Tutorial Continued: Reflection.
  
  
• SampleName.java gets the class name of an object. For supporting information see The Java Tutorial Continued: Reflection.
  
  
• SampleSuper.java finds the names of a class's ancestors. For supporting information see The Java Tutorial Continued: Reflection.
  
  

• field2.java changes the value of data fields in objects. For supporting information see Using Java Reflection.
  
  
• Method interposing example shows how to use the common interface provided by the Proxy class to encode and dispatch a method invocation to another object.
  
  
• method2.java invokes a specific method by its name. For supporting information see Using Java Reflection.
  
  
• constructor2.java finds a constructor that handles the specified parameter types and invokes it to create a new instance of the object. For supporting information see Using Java Reflection.
  
  
• SampleGet.java determines which fields belong to a class. For supporting information see The Java Tutorial Continued: Reflection.
  
  
• SampleInstance.java creates a Rectangle with the constructor that accepts two integers as parameters. For supporting information see The Java Tutorial Continued: Reflection.
  
  
• SampleInvoke.java invokes a method dynamically. For supporting information see The Java Tutorial Continued: Reflection.
  
  
• SampleNoArg.java creates an instance of the Rectangle class using the no-argument constructor. For supporting information see The Java Tutorial Continued: Reflection.
  
  
• SampleSet.java modifies the width field of a Rectangle object by invoking the set method. For supporting information see The Java Tutorial Continued: Reflection.
