IntBuffer

IntBuffer is a class in the Java NIO (New Input/Output) package that represents a buffer of primitive integers. It is a type of direct or non-direct buffer that holds a sequence of int values. Unlike arrays, IntBuffer provides methods for reading and writing data efficiently, and it can operate in either a direct or non-direct manner. Direct buffers are allocated outside the Java heap, which can offer performance advantages for I/O operations, while non-direct buffers are allocated on the heap.

IntBuffer allows for various operations on its contents, including retrieving and putting integer values at specific positions. It also supports concepts like position, limit, and capacity. The capacity of an IntBuffer is the total number of integers it can hold. The limit defines the boundary up to which the buffer can be read or written. The position indicates the index of the next element to be accessed. Methods such as get(), put(), rewind(), flip(), and clear() are commonly used to manipulate the buffer's state and access its data.

IntBuffer is often used in scenarios involving file I/O, network programming, and graphics processing where efficient handling of sequences of integer data is required. It offers a more flexible and performant alternative to traditional arrays for certain types of data manipulation.
