public ArrayFieldVector(Field<T> field)
```
    Build a 0-length vector.
    Zero-length vectors may be used to initialized construction of vectors by data gathering. We start with zero-length and use either the ArrayFieldVector(ArrayFieldVector, ArrayFieldVector) constructor or one of the append methods (append(FieldElement[]), add(FieldVector), append(ArrayFieldVector)) to gather data into this vector.
    
    Parameters:
    
    field - field to which the elements belong
  - ArrayFieldVector
```
public ArrayFieldVector(Field<T> field,
                        int size)
```
    Construct a (size)-length vector of zeros.
    
    Parameters:
    
    field - field to which the elements belong
    
    size - size of the vector
  - ArrayFieldVector
```
public ArrayFieldVector(int size,
                        T preset)
```
    Construct an (size)-length vector with preset values.
    
    Parameters:
    
    size - size of the vector
    
    preset - fill the vector with this scalar value
  - ArrayFieldVector
```
public ArrayFieldVector(T[] d)
                 throws java.lang.IllegalArgumentException
```
    Construct a vector from an array, copying the input array.
    This constructor needs a non-empty d array to retrieve the field from its first element. This implies it cannot build 0 length vectors. To build vectors from any size, one should use the ArrayFieldVector(Field, FieldElement[]) constructor.
    
    Parameters:
    
    d - array of Ts.
    
    Throws:
    
    java.lang.IllegalArgumentException - if d is empty
