  - equals
```
public boolean equals(Object obj)
```
    Compares based on the executable and the index.
    
    覆盖:
    
    equals 在类中 Object
    
    参数:
    
    obj - The object to compare.
    
    返回:
    
    Whether or not this is equal to the argument.
  - hashCode
```
public int hashCode()
```
    Returns a hash code based on the executable's hash code and the index.
    
    覆盖:
    
    hashCode 在类中 Object
    
    返回:
    
    A hash code based on the executable's hash code.
  - isNamePresent
```
public boolean isNamePresent()
```
    Returns true if the parameter has a name according to the class file; returns false otherwise. Whether a parameter has a name is determined by the MethodParameters attribute of the method which declares the parameter.
    
    返回:
    
    true if and only if the parameter has a name according to the class file.
  - toString
```
public String toString()
```
    Returns a string describing this parameter. The format is the modifiers for the parameter, if any, in canonical order as recommended by The Java™ Language Specification, followed by the fully- qualified type of the parameter (excluding the last [] if the parameter is variable arity), followed by "..." if the parameter is variable arity, followed by a space, followed by the name of the parameter.
    
    覆盖:
    
    toString 在类中 Object
    
    返回:
    
    A string representation of the parameter and associated information.
  - getDeclaringMethod
```
public Method getDeclaringMethod()
```
    Return the Executable which declares this parameter.
    
    返回:
    
    The Executable declaring this parameter.
  - getModifiers
```
public int getModifiers()
```
    Get the modifier flags for this the parameter represented by this Parameter object.
    
    返回:
    
    The modifier flags for this parameter.
  - getName
```
public String getName()
```
    Returns the name of the parameter. If the parameter's name is present, then this method returns the name provided by the class file. Otherwise, this method synthesizes a name of the form argN, where N is the index of the parameter in the descriptor of the method which declares the parameter.
    
    返回:
    
    The name of the parameter, either provided by the class file or synthesized if the class file does not provide a name.
  - getType
```
public Class<?> getType()
```
    Returns a Class object that identifies the declared type for the parameter represented by this Parameter object.
    
    返回:
    
    a Class object identifying the declared type of the parameter represented by this object
  - isImplicit
```
public boolean isImplicit()
```
    Returns true if this parameter is implicitly declared in source code; returns false otherwise.
    
    返回:
    
    true if and only if this parameter is implicitly declared as defined by The Java™ Language Specification.
  - isSynthetic
```
public boolean isSynthetic()
```
    Returns true if this parameter is neither implicitly nor explicitly declared in source code; returns false otherwise.
    
    返回:
    
    true if and only if this parameter is a synthetic construct as defined by The Java™ Language Specification.
  - isVarArgs
```
public boolean isVarArgs()
```
    Returns true if this parameter represents a variable argument list; returns false otherwise.
    
    返回:
    
    true if an only if this parameter represents a variable argument list.
  - getAnnotation
```
public <T extends Annotation> T getAnnotation(Class<T> annotationClass)
```
    指定者:
    
    getAnnotation 在接口中 AnnotatedElement
    
    抛出:
    
    NullPointerException
  - isAnnotationPresent
```
public boolean isAnnotationPresent(Class<? extends Annotation> annotationClass)
```
    指定者:
    
    isAnnotationPresent 在接口中 AnnotatedElement
  - getDeclaredAnnotations
```
public Annotation[] getDeclaredAnnotations()
```
    指定者:
    
    getDeclaredAnnotations 在接口中 AnnotatedElement
  - getDeclaredAnnotation
```
public <T extends Annotation> T getDeclaredAnnotation(Class<T> annotationClass)
```
    指定者:
    
    getDeclaredAnnotation 在接口中 AnnotatedElement
    
    抛出:
    
    NullPointerException
  - getAnnotations
```
public Annotation[] getAnnotations()
```
    指定者:
    
    getAnnotations 在接口中 AnnotatedElement
