public static record Poly.Term(int coefficient, int degree) extends Record
A non-zero term of a polynomial.

A term is a pair of a coefficient \( c \neq 0\) and a degree \( d \geq 0 \), representing \(cx^d\).

  • Field Details

    • coefficient

      private final int coefficient
      The field for the coefficient record component.

    • degree

      private final int degree
      The field for the degree record component.

  • Constructor Details

    • Term

      public Term(int coefficient, int degree)
      Creates a new term with the given coefficient and degree.
      Parameters:
      coefficient - the coefficient of the term.
      degree - the degree of the term.
      Throws:
      IllegalArgumentException - if the degree is negative or the coefficient is zero.

  • Method Details

    • toString

      public final String toString()
      Returns a string representation of this record class. The representation contains the name of the class, followed by the name and value of each of the record components.
      Specified by:
      toString in class Record
      Returns:
      a string representation of this object

    • hashCode

      public final int hashCode()
      Returns a hash code value for this object. The value is derived from the hash code of each of the record components.
      Specified by:
      hashCode in class Record
      Returns:
      a hash code value for this object

    • equals

      public final boolean equals(Object o)
      Indicates whether some other object is "equal to" this one. The objects are equal if the other object is of the same class and if all the record components are equal. All components in this record class are compared with the compare method from their corresponding wrapper classes.
      Specified by:
      equals in class Record
      Parameters:
      o - the object with which to compare
      Returns:
      true if this object is the same as the o argument; false otherwise.

    • coefficient

      public int coefficient()
      Returns the value of the coefficient record component.
      Returns:
      the value of the coefficient record component

    • degree

      public int degree()
      Returns the value of the degree record component.
      Returns:
      the value of the degree record component
