```
public static Direction[] 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 (Direction c : Direction.values())
    System.out.println(c);
```
    Returns:
    
    an array containing the constants of this enum type, in the order they are declared
  - valueOf
```
public static Direction valueOf(java.lang.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:
    
    java.lang.IllegalArgumentException - if this enum type has no constant with the specified name
    
    java.lang.NullPointerException - if the argument is null
  - isEqual
```
public boolean isEqual(Direction dir)
```
    Returns if this direction is equal to target direction. It costs 1 energy.
    
    Parameters:
    
    dir - Given direction.
    
    Returns:
    
    if this direction is equal to target direction.
  - rotateLeft
```
public Direction rotateLeft()
```
    Returns the direction obtained by rotating this direction 45 degrees to the left. It costs 1 energy.
    
    Returns:
    
    the direction obtained by rotating this direction 45 degrees to the left.
  - rotateRight
```
public Direction rotateRight()
```
    Returns the direction obtained by rotating this direction 45 degrees to the right. It costs 1 energy.
    
    Returns:
    
    the direction obtained by rotating this direction 45 degrees to the right.
  - opposite
```
public Direction opposite()
```
    Returns the opposite direction. It costs 1 energy.
    
    Returns:
    
    the opposite direction.
  - length
```
public float length()
```
    Returns the euclidean norm of this direction. It costs 2 energy.
    
    Returns:
    
    the euclidean norm of this direction.
  - getDirection
```
public static Direction getDirection(int dx,
                                     int dy)
```
    Computes the direction that moves the closest from (0,0) to (dx,dy). It costs 5 energy.
    
    Parameters:
    
    dx - x-coordinate of the target
    
    dy - y-coordinate of the target
    
    Returns:
    
    the direction that moves the closest from (0,0) to (dx,dy).
