public FloatBuffer slice()
FloatBufferThe 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 floats 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 FloatBufferpublic FloatBuffer duplicate()
FloatBufferThe 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 FloatBufferpublic FloatBuffer asReadOnlyBuffer()
FloatBufferThe 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.

get in class FloatBufferi - The index from which the float will be read
public FloatBuffer get(float[] dst,
int offset,
int length)
FloatBuffer This method transfers floats from this buffer into the given
destination array. If there are fewer floats remaining in the
buffer than are required to satisfy the request, that is, if
length > remaining(), then no
floats are transferred and a BufferUnderflowException is
thrown.
Otherwise, this method copies length floats 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 floats in
this buffer and it is potentially much more efficient.

public FloatBuffer put(float[] src,
int offset,
int length)
FloatBuffer This method transfers floats into this buffer from the given
source array. If there are more floats to be copied from the array
than remain in this buffer, that is, if
length > remaining(), then no
floats are transferred and a BufferOverflowException is
thrown.
Otherwise, this method copies length floats 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 FloatBuffersrc - The array from which floats are to be readoffset - The offset within the array of the first float to be read;
must be non-negative and no larger than array.lengthlength - The number of floats to be read from the given array;
must be non-negative and no larger than
array.length - offset
public FloatBuffer put(FloatBuffer src)
FloatBuffer This method transfers the floats remaining in the given source
buffer into this buffer. If there are more floats remaining in the
source buffer than in this buffer, that is, if
src.remaining() > remaining(),
then no floats are transferred and a BufferOverflowException is thrown.
Otherwise, this method copies n = src.remaining() floats 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 FloatBuffersrc - The source buffer from which floats are to be read;
must not be this buffer
public FloatBuffer compact()
FloatBufferThe floats between the buffer's current position and its limit, if any, are copied to the beginning of the buffer. That is, the float at index p = position() is copied to index zero, the float at index p + 1 is copied to index one, and so forth until the float 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 floats copied, rather than to zero, so that an invocation of this method can be followed immediately by an invocation of another relative put method.
compact in class FloatBufferpublic ByteOrder order()
FloatBuffer The byte order of a float buffer created by allocation or by
wrapping an existing float array is the native order of the underlying
hardware. The byte order of a float buffer created as a view of a byte buffer is that of the
byte buffer at the moment that the view is created.
