Explains memory padding in Java — the practice of inserting unused bytes to align data at addresses divisible by 4 or 8, which allows CPUs to read and write 32-bit or 64-bit words more efficiently. The JVM automatically handles padding and can optimize object memory layout to minimize it. Also briefly mentions that JDK 22's memory API supports reading unaligned data for cases where files lack padding.
