public static void loadLibrary(String libname)

throws SecurityException, UnsatisfiedLinkError

This method loads a library code file with the specified library name from the

local file system.

The call

System.loadLibrary(name)

 is effectively equivalent to the call

Runtime.getRuntime().loadLibrary(name)

For a more complete description, see the

loadLibrary

 method of class

Runtime

( 20.16.14).

public static void arraycopy(Object src, int srcOffset,

Object dst, int dstOffset, int length)

throws NullPointerException, ArrayStoreException,

IndexOutOfBoundsException

A subsequence of array components is copied from the source array referenced by

src

 to the destination array referenced by

dst

. The number of components copied

is equal to the

length

 argument. The components at the positions

srcOffset

through

srcOffset+length 1

 in the source array are copied into the positions

dstOffset

 through

dstOffset+length 1

, respectively, of the destination array.

If the

src

 and

dst

 arguments refer to the same array object, then copying is

performed as if the components of the source array at positions

srcOffset

through

srcOffset+length 1

 were first copied to a temporary array of length

length

 and then the contents of the temporary array were copied into positions

dstOffset

 through

dstOffset+length 1

 of the destination array.

If

dst

 is

null

, then a

NullPointerException

 is thrown.

If

src

 is

null

, then a

NullPointerException

 is thrown and the destination

array is not modified.

Otherwise, if any of the following is true, then an

ArrayStoreException

 is

thrown and the destination is not modified:

The

src

 argument refers to an object that is not an array.

The

dst

 argument refers to an object that is not an array.

The

src

 argument and

dst

 argument refer to arrays whose component types

are different primitive types.

The

src

 argument refers to an array of primitive component type and the

dst

argument refers to an array of reference component type.
