```
public boolean equals(java.lang.Object obj)
```
    Compares this Constructor against the specified object. Returns true if the objects are the same. Two Constructor objects are the same if they were declared by the same class and have the same formal parameter types.
    
    Overrides:
    
    equals in class java.lang.Object
  - hashCode
```
public int hashCode()
```

  - toString
```
public java.lang.String toString()
```
    Returns a string describing this Constructor. The string is formatted as the constructor access modifiers, if any, followed by the fully-qualified name of the declaring class, followed by a parenthesized, comma-separated list of the constructor's formal parameter types. For example:
```
    public java.util.Hashtable(int,float)
 
```
    The only possible modifiers for constructors are the access modifiers public, protected or private. Only one of these may appear, or none if the constructor has default (package) access.
    Overrides:
    
    toString in class java.lang.Object
    
    Returns:
    
    a string describing this Constructor
  - toGenericString
```
public java.lang.String toGenericString()
```
    Returns a string describing this Constructor, including type parameters. The string is formatted as the constructor access modifiers, if any, followed by an angle-bracketed comma separated list of the constructor's type parameters, if any, followed by the fully-qualified name of the declaring class, followed by a parenthesized, comma-separated list of the constructor's generic formal parameter types.
    If this constructor was declared to take a variable number of arguments, instead of denoting the last parameter as "Type[]", it is denoted as "Type...".
    A space is used to separate access modifiers from one another and from the type parameters or return type. If there are no type parameters, the type parameter list is elided; if the type parameter list is present, a space separates the list from the class name. If the constructor is declared to throw exceptions, the parameter list is followed by a space, followed by the word "throws" followed by a comma-separated list of the thrown exception types.
    The only possible modifiers for constructors are the access modifiers public, protected or private. Only one of these may appear, or none if the constructor has default (package) access.
    
    Specified by:
    
    toGenericString in class Executable

  - newInstance
```
public T newInstance(java.lang.Object... initargs)
              throws java.lang.InstantiationException,
                     java.lang.IllegalAccessException,
                     java.lang.IllegalArgumentException,
                     java.lang.reflect.InvocationTargetException
```
    Uses the constructor represented by this Constructor object to create and initialize a new instance of the constructor's declaring class, with the specified initialization parameters. Individual parameters are automatically unwrapped to match primitive formal parameters, and both primitive and reference parameters are subject to method invocation conversions as necessary.
    If the number of formal parameters required by the underlying constructor is 0, the supplied initargs array may be of length 0 or null.
    If the constructor's declaring class is an inner class in a non-static context, the first argument to the constructor needs to be the enclosing instance; see section 15.9.3 of The Java™ Language Specification.
    If the required access and argument checks succeed and the instantiation will proceed, the constructor's declaring class is initialized if it has not already been initialized.
    If the constructor completes normally, returns the newly created and initialized instance.
    
    Parameters:
    
    initargs - array of objects to be passed as arguments to the constructor call; values of primitive types are wrapped in a wrapper object of the appropriate type (e.g. a float in a Float)
    
    Returns:
    
    a new object created by calling the constructor this object represents
    
    Throws:
    
    java.lang.IllegalAccessException - if this Constructor object is enforcing Java language access control and the underlying constructor is inaccessible.
    
    java.lang.IllegalArgumentException - if the number of actual and formal parameters differ; if an unwrapping conversion for primitive arguments fails; or if, after possible unwrapping, a parameter value cannot be converted to the corresponding formal parameter type by a method invocation conversion; if this constructor pertains to an enum type.
    
    java.lang.InstantiationException - if the class that declares the underlying constructor represents an abstract class.
    
    java.lang.reflect.InvocationTargetException - if the underlying constructor throws an exception.
    
    java.lang.ExceptionInInitializerError - if the initialization provoked by this method fails.

  - getParameterAnnotations
```
public java.lang.annotation.Annotation[][] getParameterAnnotations()
```
    Returns an array of arrays of Annotations that represent the annotations on the formal parameters, in declaration order, of the Executable represented by this object. Synthetic and mandated parameters (see explanation below), such as the outer "this" parameter to an inner class constructor will be represented in the returned array. If the executable has no parameters (meaning no formal, no synthetic, and no mandated parameters), a zero-length array will be returned. If the Executable has one or more parameters, a nested array of length zero is returned for each parameter with no annotations. The annotation objects contained in the returned arrays are serializable. The caller of this method is free to modify the returned arrays; it will have no effect on the arrays returned to other callers.
    A compiler may add extra parameters that are implicitly declared in source ("mandated"), as well as parameters that are neither implicitly nor explicitly declared in source ("synthetic") to the parameter list for a method. See Parameter for more information.
    
    Specified by:
    
    getParameterAnnotations in class Executable
