- Method Detail
  - getInstance
```
public static FractionField getInstance()
```
    Get the unique instance.
    
    Returns:
    
    the unique instance
  - getOne
```
public Fraction getOne()
```
    Get the multiplicative identity of the field.
    The multiplicative identity is the element e₁ of the field such that for all elements a of the field, the equalities a × e₁ = e₁ × a = a hold.
    
    Specified by:
    
    getOne in interface Field<Fraction>
    
    Returns:
    
    multiplicative identity of the field
  - getZero
```
public Fraction getZero()
```
    Get the additive identity of the field.
    The additive identity is the element e₀ of the field such that for all elements a of the field, the equalities a + e₀ = e₀ + a = a hold.
    
    Specified by:
    
    getZero in interface Field<Fraction>
    
    Returns:
    
    additive identity of the field
  - getRuntimeClass
```
public Class<? extends FieldElement<Fraction>> getRuntimeClass()
```
    Returns the runtime class of the FieldElement.
    
    Specified by:
    
    getRuntimeClass in interface Field<Fraction>
    
    Returns:
    
    The Class object that represents the runtime class of this object.
  - equals
```
public boolean equals(Object other)
```
    Overrides:
    
    equals in class Object
  - hashCode
```
public int hashCode()
```
    Overrides:
    
    hashCode in class Object
