   The ByteBuffer class is important because it forms a basis for the use of channels in Java. ByteBuffer class defines six categories of operations upon byte buffers, as stated in the Java 7 documentation: Methods for compacting, duplicating, and slicing a byte buffer. Example code : Putting Bytes into a buffer.

   Aug 10, 2024 · Conceptually, the ByteBuffer class is a byte array wrapped inside an object. It provides many convenient methods to facilitate reading or writing operations from/to underlying data. These methods are highly dependent on the indices maintained. Now, let’s deliberately simplify the ByteBuffer class into a container of byte array with extra indices:

   Mar 12, 2024 · Java ByteBuffers provide a way to allocate and manage memory outside of the Java heap. They are part of the java.nio package and are especially useful when working with I/O operations, networking, and direct memory access. The ByteBuffer class allows direct access to native memory, which can be leveraged to improve performance and avoid certain ...

   Dec 20, 2012 · 1. 2. int first = bb.getInt(); int second = bb.getInt(); The second option is often convenient, but at the cost of having a side-effect on the buffer (i.e., changing it). Not the contents itself, but the ByteBuffers view into that content. In this way, ByteBuffers can behave similarly to a stream, if used as such.

   What is a byte buffer?

   • A ByteBuffer has value semantics with respect to hashCode () / equals () and as a result can be more conveniently used in containers. A ByteBuffer has offers the ability to pass around a subset of a byte buffer as a value without copying the bytes, by instantiating a new ByteBuffer. The NIO API makes extensive use of ByteBuffer:s.

   The byte order of a view buffer is fixed to be that of its byte buffer at the time that the view is created. Invocation chaining. Methods in this class that do not otherwise have a value to return are specified to return the buffer upon which they are invoked. This allows method invocations to be chained.
