This is a type alias for java.util.ConcurrentModificationException

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
. 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.

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
Class
object of the component type of the array - length
-
the length of the new array.
Attributes
- 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
elemClass
isnull
. - Example
-
val a = scala.compat.Platform.createArray(classOf[Int], 4).asInstanceOf[Array[Int]] // returns Array[Int](0, 0, 0, 0)

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.
Attributes
- Returns
-
the
Class
object 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
