IntBufferThe content of the new buffer will start at this buffer's current position. Changes to this buffer's content will be visible in the new buffer, and vice versa; the two buffers' position, limit, and mark values will be independent.
The new buffer's position will be zero, its capacity and its limit will be the number of ints remaining in this buffer, and its mark will be undefined. The new buffer will be direct if, and only if, this buffer is direct, and it will be read-only if, and only if, this buffer is read-only.
slice in class IntBufferpublic IntBuffer duplicate()
IntBufferThe content of the new buffer will be that of this buffer. Changes to this buffer's content will be visible in the new buffer, and vice versa; the two buffers' position, limit, and mark values will be independent.
The new buffer's capacity, limit, position, and mark values will be identical to those of this buffer. The new buffer will be direct if, and only if, this buffer is direct, and it will be read-only if, and only if, this buffer is read-only.
duplicate in class IntBufferpublic IntBuffer asReadOnlyBuffer()
IntBufferThe content of the new buffer will be that of this buffer. Changes to this buffer's content will be visible in the new buffer; the new buffer itself, however, will be read-only and will not allow the shared content to be modified. The two buffers' position, limit, and mark values will be independent.
The new buffer's capacity, limit, position, and mark values will be identical to those of this buffer.
If this buffer is itself read-only then this method behaves in
exactly the same way as the duplicate method.

public IntBuffer get(int[] dst,
int offset,
int length)
IntBuffer This method transfers ints from this buffer into the given
destination array. If there are fewer ints remaining in the
buffer than are required to satisfy the request, that is, if
length > remaining(), then no
ints are transferred and a BufferUnderflowException is
thrown.
Otherwise, this method copies length ints from this buffer into the given array, starting at the current position of this buffer and at the given offset in the array. The position of this buffer is then incremented by length.
In other words, an invocation of this method of the form src.get(dst, off, len) has exactly the same effect as the loop
for (int i = off; i < off + len; i++)
dst[i] = src.get();
except that it first checks that there are sufficient ints in
this buffer and it is potentially much more efficient.

dst.lengthlength - The maximum number of ints to be written to the given
array; must be non-negative and no larger than

public IntBuffer put(int x)
IntBufferWrites the given int into this buffer at the current position, and then increments the position.
put in class IntBufferx - The int to be written
public IntBuffer put(int i,
int x)
IntBufferWrites the given int into this buffer at the given index.
put in class IntBufferi - The index at which the int will be writtenx - The int value to be written
public IntBuffer put(IntBuffer src)
IntBuffer This method transfers the ints remaining in the given source
buffer into this buffer. If there are more ints remaining in the
source buffer than in this buffer, that is, if
src.remaining() > remaining(),
then no ints are transferred and a BufferOverflowException is thrown.
Otherwise, this method copies n = src.remaining() ints from the given buffer into this buffer, starting at each buffer's current position. The positions of both buffers are then incremented by n.
In other words, an invocation of this method of the form dst.put(src) has exactly the same effect as the loop
while (src.hasRemaining())
dst.put(src.get());
except that it first checks that there is sufficient space in this
buffer and it is potentially much more efficient.
put in class IntBuffersrc - The source buffer from which ints are to be read;

public IntBuffer put(int[] src,
int offset,
int length)
IntBuffer This method transfers ints into this buffer from the given
source array. If there are more ints to be copied from the array
than remain in this buffer, that is, if
length > remaining(), then no
ints are transferred and a BufferOverflowException is
thrown.
Otherwise, this method copies length ints from the given array into this buffer, starting at the given offset in the array and at the current position of this buffer. The position of this buffer is then incremented by length.
In other words, an invocation of this method of the form dst.put(src, off, len) has exactly the same effect as the loop
for (int i = off; i < off + len; i++)
dst.put(a[i]);
except that it first checks that there is sufficient space in this
buffer and it is potentially much more efficient.
put in class IntBuffersrc - The array from which ints are to be readoffset - The offset within the array of the first int to be read;
must be non-negative and no larger than array.lengthlength - The number of ints to be read from the given array;
must be non-negative and no larger than
array.length - offset
public IntBuffer compact()
IntBufferThe ints between the buffer's current position and its limit, if any, are copied to the beginning of the buffer. That is, the int at index p = position() is copied to index zero, the int at index p + 1 is copied to index one, and so forth until the int at index limit() - 1 is copied to index n = limit() - 1 - p. The buffer's position is then set to n+1 and its limit is set to its capacity. The mark, if defined, is discarded.
The buffer's position is set to the number of ints copied, rather than to zero, so that an invocation of this method can be followed immediately by an invocation of another relative put method.

IntBuffer The byte order of a int buffer created by allocation or by
wrapping an existing int array is the native order of the underlying
hardware. The byte order of a int buffer created as a view of a byte buffer is that of the
byte buffer at the moment that the view is created.
