*** ** * ** ***
A `Method` provides information about, and access to, a single method on a class or interface. The reflected method may be a class method or an instance method (including an abstract method).
A `Method` permits widening conversions to occur when matching the actual parameters to invoke with the underlying method's formal parameters, but it throws an `IllegalArgumentException` if a narrowing conversion would occur.

### getTypeParameters
Added in [API level 1](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)
```
public TypeVariable[] getTypeParameters ()
```
Returns an array of `TypeVariable` objects that represent the type variables declared by the generic declaration represented by this `GenericDeclaration` object, in declaration order. Returns an array of length 0 if the underlying generic declaration declares no type variables.

### hashCode
Added in [API level 1](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)
```
public int hashCode ()
```
Returns a hashcode for this `Method`. The hashcode is computed as the exclusive-or of the hashcodes for the underlying method's declaring class name and the method's name.
| Returns ||
|---|---|
| `int` | a hash code value for this object.
|
### invoke
Added in [API level 1](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)
```
public Object invoke (Object obj,
Object... args)
```
Invokes the underlying method represented by this `Method` object, on the specified object with the specified 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 underlying method is static, then the specified `obj` argument is ignored. It may be null.
If the number of formal parameters required by the underlying method is 0, the supplied `args` array may be of length 0 or null.
If the underlying method is an instance method, it is invoked using dynamic method lookup as documented in The Java Language Specification, Second Edition, section 15.12.4.4; in particular, overriding based on the runtime type of the target object will occur.
If the underlying method is static, the class that declared the method is initialized if it has not already been initialized.
If the method completes normally, the value it returns is returned to the caller of invoke; if the value has a primitive type, it is first appropriately wrapped in an object. However, if the value has the type of an array of a primitive type, the elements of the array are *not* wrapped in objects; in other words, an array of primitive type is returned. If the underlying method return type is void, the invocation returns null.
| Parameters ||
|---|---|
| `obj` | `Object`: the object the underlying method is invoked from
|
| `args` | `Object`: the arguments used for the method call
|
| Returns ||
|---|---|
| `https://developer.android.com/reference/java/lang/Object` | the result of dispatching the method represented by this object on `obj` with parameters `args`
|
| Throws ||
|---|---|
| `https://developer.android.com/reference/java/lang/ExceptionInInitializerError` | if the initialization provoked by this method fails. |
| `https://developer.android.com/reference/java/lang/IllegalAccessException` | if this `Method` object is enforcing Java language access control and the underlying method is inaccessible. |
| `https://developer.android.com/reference/java/lang/IllegalArgumentException` | if the method is an instance method and the specified object argument is not an instance of the class or interface declaring the underlying method (or of a subclass or implementor thereof); 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. |
| `https://developer.android.com/reference/java/lang/NullPointerException` | if the specified object is null and the method is an instance method. |
| `https://developer.android.com/reference/java/lang/reflect/InvocationTargetException` | if the underlying method throws an exception. |
### isBridge
Added in [API level 1](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)

public boolean isVarArgs ()
```
Returns `true` if this executable was declared to take a variable number of arguments; returns `false` otherwise.
| Returns ||
|---|---|
| `boolean` | `true` if an only if this executable was declared to take a variable number of arguments.

### toGenericString
Added in [API level 1](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)
```
public String toGenericString ()
```
Returns a string describing this `Method`, including type parameters. The string is formatted as the method access modifiers, if any, followed by an angle-bracketed comma-separated list of the method's type parameters, if any, followed by the method's generic return type, followed by a space, followed by the class declaring the method, followed by a period, followed by the method name, followed by a parenthesized, comma-separated list of the method's generic formal parameter types. If this method 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 method 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 generic thrown exception types.
The access modifiers are placed in canonical order as specified by "The Java Language Specification". This is `public`, `protected` or `private` first, and then other modifiers in the following order: `abstract`, `default`, `static`, `final`, `synchronized`, `native`, `strictfp`.
| Returns ||
|---|---|
| `https://developer.android.com/reference/java/lang/String` | a string describing this `Method`, include type parameters
|
### toString
Added in [API level 1](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)
```
public String toString ()
```
Returns a string describing this `Method`. The string is formatted as the method access modifiers, if any, followed by the method return type, followed by a space, followed by the class declaring the method, followed by a period, followed by the method name, followed by a parenthesized, comma-separated list of the method's formal parameter types. If the method throws checked 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. For example:
```
public boolean java.lang.Object.equals(java.lang.Object)
```
The access modifiers are placed in canonical order as specified by "The Java Language Specification". This is `public`, `protected` or `private` first, and then other modifiers in the following order: `abstract`, `default`, `static`, `final`, `synchronized`, `native`, `strictfp`.
| Returns ||
|---|---|
| `https://developer.android.com/reference/java/lang/String` | a string describing this `Method`
