This is a type alias forjava.util.ConcurrentModificationException, which may be thrown by methods that detect an invalid modification of an object.
This is a type alias forjava.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 forjava.lang.StackOverflowError, which itself extendsjava.lang.Error. The same rules apply to catching ajava.lang.Error as for Java, that it indicates a serious problem that a reasonable application should not try and catch.

Copieslength elements of arraysrc starting at positionsrcPos to the arraydest starting at positiondestPos.
Copieslength elements of arraysrc starting at positionsrcPos to the arraydest starting at positiondestPos. Ifsrc==dest, the copying will behave as if the elements copied fromsrc 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.
Attributes
- Throws
java.lang.ArrayStoreExceptionIf either
srcordestare not of type [java.lang.Array]; or if the element type ofsrcis not compatible with that ofdest.java.lang.IndexOutOfBoundsExceptionIf either

Runs the garbage collector.
Runs the garbage collector.
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.

- Platform.scala
Creates a new array of the specified type and given length.
Creates a new array of the specified type and given length.
Note that ifelemClass is a subclass ofscala.AnyVal then the returned value is an Array of the corresponding java primitive type. For example, the following codescala.compat.Platform.createArray(classOf[Int], 4) returns an array of the java primitive typeint.
For ascala.AnyVal array, the values of the array are set to 0 fornumeric value types (scala.Double,scala.Float,scala.Long,scala.Int,scala.Char,scala.Short, andscala.Byte), andfalse forscala.Boolean. Creation of an array of typescala.Unit is not possible.
For subclasses ofscala.AnyRef, the values of the array are set tonull.
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.
Attributes
- Returns
an array of the given component type as an
AnyRef.- Throws
java.lang.IllegalArgumentExceptionif componentType isscala.Unit or

val a = scala.compat.Platform.createArray(classOf[Int], 4).asInstanceOf[Array[Int]] // returns Array[Int](0, 0, 0, 0)- Deprecated

Returns theClass object associated with the class or interface with the given string name using the currentClassLoader.
Returns theClass object associated with the class or interface with the given string name using the currentClassLoader. On the JVM, invoking this method is equivalent to:java.lang.Class.forName(name)
For more information, please see the Java documentation forjava.lang.Class.
Value parameters
- name
the fully qualified name of the desired class.
Attributes
- 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
