Common HTTP methods defined by the HTTP specification.
Each method is:
- Either safe or unsafe: An HTTP method is safe if it doesn't change the state of the server. In other words, a method is safe if it's read-only.
- Either idempotent or non-idempotent: An HTTP method is idempotent if making a single request has the same effect as making several identical requests. All safe methods are also idempotent, but not all idempotent methods are safe. For example, PUT and DELETE are both idempotent but unsafe.

- Method Detail
  - values
```
public static Method[] values()
```
    Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:
```
for (Method c : Method.values())
    System.out.println(c);
```
    Returns:
    
    an array containing the constants of this enum type, in the order they are declared
  - valueOf
```
public static Method valueOf(String name)
```
    Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)
    
    Parameters:
    
    name - the name of the enum constant to be returned.
    
    Returns:
    
    the enum constant with the specified name
    
    Throws:
    
    IllegalArgumentException - if this enum type has no constant with the specified name
    
    NullPointerException - if the argument is null
  - isSafe
```
public boolean isSafe()
```
    Tests whether this method is safe.
    
    Returns:
    
    whether this method is safe.
  - isIdempotent
```
public boolean isIdempotent()
```
    Tests whether this method is idempotent.
    
    Returns:
    
    whether this method is idempotent.
  - isSafe
```
public static boolean isSafe(String value)
```
  - isIdempotent
```
public static boolean isIdempotent(String value)
```
  - normalizedValueOf
```
public static Method normalizedValueOf(String method)
```
    Returns the Method for a normalized value of a method name.
    
    Parameters:
    
    method - A method name like "delete", "DELETE", or any mixed-case variant.
    
    Returns:
    
    the Method for the given method name.
  - isSame
```
public boolean isSame(String value)
```
