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.

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.
- Value parameters:
- dest
A non-null array as destination for the copy.
- destPos
The starting index in the destination array.
- length
The number of elements to be copied.
- src
A non-null array as source for the copy.
- srcPos
The starting index in the source array.
- Throws:
- java.lang.ArrayStoreException
If either
srcordestare not of type [java.lang.Array]; or if the element type ofsrcis not compatible with that ofdest.- java.lang.IndexOutOfBoundsException
If either
srcPosordestPosare outside of the bounds of their respective arrays; or iflengthis negative; or if there are less thanlengthelements available aftersrcPosordestPosinsrcanddestrespectively.- java.lang.NullPointerException

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.
- Value parameters:
- elemClass
the
Classobject of the component type of the array- length
the length of the new array.
- Returns:
an array of the given component type as an
AnyRef.- Throws:
- java.lang.IllegalArgumentException
if componentType is scala.Unit or
java.lang.Void.TYPE- java.lang.NegativeArraySizeException
if the specified length is negative
- java.lang.NullPointerException
If
elemClassisnull.
- Example:
val a = scala.compat.Platform.createArray(classOf[Int], 4).asInstanceOf[Array[Int]] // returns Array[Int](0, 0, 0, 0)- Deprecated

Returns the Class object associated with the class or interface with the given string name using the current ClassLoader.
On the JVM, invoking this method is equivalent to: java.lang.Class.forName(name)
For more information, please see the Java documentation for java.lang.Class.
- Value parameters:
- name
the fully qualified name of the desired class.
- Returns:
the
Classobject for the class with the specified name.- Throws:
- java.lang.ClassNotFoundException
if the class cannot be located
- java.lang.ExceptionInInitializerError
if the initialization provoked by this method fails
- java.lang.LinkageError
if the linkage fails
- Example:
val a = scala.compat.Platform.getClassForName("java.lang.Integer") // returns the Class[_] for java.lang.Integer- Deprecated
