### Type Members

1. #### type ConcurrentModificationException = 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.

   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.

2. #### type StackOverflowError = java.lang.StackOverflowError

   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.

### Value Members

3. #### final def ==(arg0: Any): Boolean

4. #### val EOL: String

   The default line separator.

   The default line separator.

   On the JVM, this is equivalent to calling the method: `System.getProperty("line.separator")` with a default value of "\n".

5. #### def arrayclear(arr: Array[Int]): Unit

   Assigns the value of 0 to each element in the array.

   Assigns the value of 0 to each element in the array.

   arr

     A non-null Array[Int].

   Annotations
     @inline()
   Exceptions thrown
     `java.lang.NullPointerException`

     If `arr` is `null`.

6. #### def arraycopy(src: AnyRef, srcPos: Int, dest: AnyRef, destPos: Int, length: Int): Unit

   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.

   src

     A non-null array as source for the copy.

   srcPos

     The starting index in the source array.

   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.

   Annotations
     @inline()
   Exceptions thrown
     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`.

9. #### def collectGarbage(): Unit

   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.

10. #### def createArray(elemClass: Class[_], length: Int): AnyRef

    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.

    elemClass

      the `Class` object 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`.

    Annotations
      @inline()
    Example:

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

    Exceptions thrown
      `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` is `null`.

11. #### def currentTime: Long

    The current time in milliseconds.

    The current time in milliseconds. The time is counted since 1 January 1970 UTC.

    Note that the operating system timer used to obtain this value may be less precise than a millisecond.

17. #### def getClassForName(name: String): Class[_]

    Returns the `Class` object associated with the class or interface with the given string name using the current `ClassLoader`.

    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.

    name

      the fully qualified name of the desired class.

    returns

      the `Class` object for the class with the specified name.
