1. def equals(arg0: Any): Boolean

   This method is used to compare the receiver object (this) with the argument object (arg0) for equivalence

   This method is used to compare the receiver object (this) with the argument object (arg0) for equivalence.

   The default implementations of this method is an equivalence relation:

   • It is reflexive: for any instance x of type Any, x.equals(x) should return true.
   • It is symmetric: for any instances x and y of type Any, x.equals(y) should return true if and only if y.equals(x) returns true.
   • It is transitive: for any instances x, y, and z of type AnyRef if x.equals(y) returns true and y.equals(z) returns true, then x.equals(z) should return true.

   If you override this method, you should verify that your implementation remains an equivalence relation. Additionally, when overriding this method it is often necessary to override hashCode to ensure that objects that are "equal" (o1.equals(o2) returns true) hash to the same Int (o1.hashCode.equals(o2.hashCode)).

   arg0

   the object to compare against this object for equality.

   returns

   true if the receiver object is equivalent to the argument; false otherwise.

2. def hashCode(): Int

   Returns a hash code value for the object

   Returns a hash code value for the object.

   The default hashing algorithm is platform dependent.

   Note that it is allowed for two objects to have identical hash codes (o1.hashCode.equals(o2.hashCode)) yet not be equal (o1.equals(o2) returns false). A degenerate implementation could always return 0. However, it is required that if two objects are equal (o1.equals(o2) returns true) that they have identical hash codes (o1.hashCode.equals(o2.hashCode)). Therefore, when overriding this method, be sure to verify that the behavior is consistent with the equals method.

10. def nextInt(): Int

    Returns the next pseudorandom, uniformly distributed int value from this random number generator's sequence

    Returns the next pseudorandom, uniformly distributed int value from this random number generator's sequence.

11. def nextLong(): Long

    Returns the next pseudorandom, uniformly distributed long value from this random number generator's sequence

    definition classes: Random

12. def nextString(length: Int): String

    Returns a pseudorandomly generated String

    Returns a pseudorandomly generated String. This routine does not take any measures to preserve the randomness of the distribution in the face of factors like unicode's variable-length encoding, so please don't use this for anything important. It's primarily intended for generating test data.

    length

    the desired length of the String

    returns

    the String

13. val self: Random

14. def setSeed(seed: Long): Unit

    Returns a new collection of the same type in a randomly chosen order

    Returns a new collection of the same type in a randomly chosen order.

    coll

    the Traversable to shuffle

    returns

    the shuffled Traversable

16. def toString(): String

    Returns a string representation of the object

    Returns a string representation of the object.

    The default representation is platform dependent.
