May 26, 2009 · The byte array would take less memory unless you had several copies of the string, in which case the string would take up less memory thanks to the string table. But the real questions is, does it really matter? There are a lot of benefits you get to using the string as a string, rather than storing it as an array of bytes.
Oct 23, 2008 · 20. Yes, a byte variable in Java is in fact 4 bytes in memory. However this doesn't hold true for arrays. The storage of a byte array of 20 bytes is in fact only 20 bytes in memory. That is because the Java Bytecode Language only knows two integer number types: ints and longs.
A byte array in Java is an array of bytes used to store binary data. The byte data type takes 8 bits of memory and can store values from 0 to 255. Unlike arrays of primitive types like ints or floats, a byte array can hold raw binary data as-is, without any conversion. This makes it very efficient for storing data like: Some key advantages of ...

Here are some questions to test your knowledge and understanding of byte arrays in Python:What is a byte array in Python, and how is it different from bytes and strings?How do you create a byte array in Python, and what methods can be used to modify it?What are some applications of byte arrays in Python, and in what scenarios would you prefer to use them over other data types?Aug 21, 2023 · Example of an array of integers and assigning to Random Access Memory. Integers commonly occupy 4 bytes in RAM. While storing an array, an address is associated with each value.
Jan 11, 2024 · Code Explanation: The code defines a ByteArray class capable of handling byte-level data. The ByteArray class internally uses a std::vector<uint8_t> to store bytes, providing methods to append data and read data from it. The append method takes a pointer to some data and the number of bytes to append.
