I have a byte's array and I want to calculate what would be the file size if I'll write these bytes to file. Is it possible without writing the file to disc?

Find length of one array element in bytes and total bytes consumed by the elements in Numpy. In NumPy we can find the length of one array element in a byte with the help of itemsize . It will return the length of the array in integer.
To get the entire buffer, use the GetBuffer method. This method returns a copy of the contents of the MemoryStream as a byte array. If the current instance was constructed on a provided byte array, a copy of the section of the array to which this instance has access is returned.
You can simply iterate the byte array and print the byte using System. out. println() method.
Convert byte[] array to File using Java In order to convert a byte array to a file, we will be using a method named the getBytes() method of String class. Implementation: Convert a String into a byte array and write it in a file.
What about array.Length? Looks like a size in bytes.
