This is a type alias for java.util.ConcurrentModificationException,
which may be thrown by methods that detect an invalid modification of an object.
This is a type alias for java.util.ConcurrentModificationException,
which may be thrown by methods that detect an invalid modification of an object.
For example, many common collection types do not allow modifying a collection
while it is being iterated over.
Thrown when a stack overflow occurs because a method or function recurses too deeply.
Thrown when a stack overflow occurs because a method or function recurses too deeply.
On the JVM, this is a type alias for java.lang.StackOverflowError, which itself extends java.lang.Error.
The same rules apply to catching a java.lang.Error as for Java, that it indicates a serious problem that a reasonable application should not try and catch.

Equivalent to x.hashCode except for boxed numeric types and null.
For numerics, it returns a hash value which is consistent
with value equality: if two value type instances compare
as true, then ## will produce the same hash value for each
of them.
For null returns a hashcode where null.hashCode throws a
NullPointerException.

On the JVM, this is equivalent to calling the method:

Copies length elements of array src starting at position srcPos to the
array dest starting at position destPos.
Copies length elements of array src starting at position srcPos to the
array dest starting at position destPos. If src==dest, the copying will
behave as if the elements copied from src were first copied to a temporary
array before being copied back into the array at the destination positions.

java.lang.ArrayStoreException If either src or dest are not of type
[java.lang.Array]; or if the element type of src is not
compatible with that of dest.
java.lang.IndexOutOfBoundsException If either srcPos or destPos are
outside of the bounds of their respective arrays; or if length
is negative; or if there are less than length elements available
after srcPos or destPos in src and dest respectively.
java.lang.NullPointerException If either src or dest are null.
Cast the receiver object to be of type T0.
Cast the receiver object to be of type T0.
Note that the success of a cast at runtime is modulo Scala's erasure semantics.
Therefore the expression 1.asInstanceOf[String] will throw a ClassCastException at
runtime, while the expression List(1).asInstanceOf[List[String]] will not.
In the latter example, because the type argument is erased as part of compilation it is
not possible to check whether the contents of the list are of the requested type.

ClassCastException if the receiver object is not an instance of the erasure of type T0.

This is a request that the underlying JVM runs the garbage collector. The results of this call depends heavily on the JVM used. The underlying JVM is free to ignore this request.
Creates a new array of the specified type and given length.
Creates a new array of the specified type and given length.
Note that if elemClass is a subclass of scala.AnyVal then the returned value is an Array of the corresponding java primitive type.
For example, the following code scala.compat.Platform.createArray(classOf[Int], 4) returns an array of the java primitive type int.
For a scala.AnyVal array, the values of the array are set to 0 for numeric value types (scala.Double, scala.Float, scala.Long, scala.Int, scala.Char,
scala.Short, and scala.Byte), and false for scala.Boolean. Creation of an array of type scala.Unit is not possible.
For subclasses of scala.AnyRef, the values of the array are set to null.
The caller must cast the returned value to the correct type.

Tests whether the argument (arg0) is a reference to the receiver object (this).
Tests whether the argument (arg0) is a reference to the receiver object (this).
The eq method implements an equivalence relation on
non-null instances of AnyRef, and has three additional properties:
x and y of type AnyRef, multiple invocations of
x.eq(y) consistently returns true or consistently returns false.x of type AnyRef, x.eq(null) and null.eq(x) returns false.null.eq(null) returns true. When overriding the equals or hashCode methods, it is important to ensure that their behavior is
consistent with reference equality. Therefore, if two objects are references to each other (o1 eq o2), they
should be equal to each other (o1 == o2) and they should hash to the same value (o1.hashCode == o2.hashCode).

The details of when and if the finalize method is invoked, as
well as the interaction between finalize and non-local returns
and exceptions, are all platform dependent.
