float usually 4
double usually 8
long is 8 but integer, unlike double
string is a pointer to a memory address containing array of chars, so it doesn't have a fixed size
and a char is usually 1, but i think its 2 in java
In Java, you can use either a float or a double
four
about eight bits, which is equal to one byte
double or float
It means that you can only store values like Integer, String etc in a Vector and not values like int, float etc. int, float, double etc are primitive data types. collections by their default behavior can hold only objects and not primitives.
In SQL, the storage size of a VARCHAR data type is determined by the length of the string stored in it, plus an additional byte (or two bytes for very large strings) to store the length of the string. Specifically, it uses 1 byte for strings up to 255 characters and 2 bytes for strings longer than 255 characters. Therefore, the total size in bytes for a VARCHAR(n) can be up to n + 1 or n + 2, depending on the length of the data.
how many bytes are there in a 64-bit machine? Another Answer: It takes 8 bytes to store a 64 bit number.
A system with a capacity of 232 bytes can store 4,294,967,296 bytes of data.

61440 Mega Bytes(MB) that is 62914560 Kilo bytes(KB) that is 64424509440 BYTES....- Mayank
Different computer languages use different amounts of memory to store integers. For example, C++ uses a minimum of 4 bytes, Java a min of 8 bytes. A long integer is one which is requires more bytes than the standard amount. When the storage requirement gets to twice the standard amount, the number becomes a double integer.
32767 is the maximum value that can be stored in two bytes.
Floating point types are used to represent fractional numbers. In both C and Java the names for these types are float and double. double offers greater precision than float.
4 - one for each character. However, depending on the computer language being used, there is some "overhead" - for example, with "C", the end of a text string is indicated with a null character, so "Bill" would need 5 bytes. Other languages precede strings with their length, the length taking 2, 4 or 8 bytes.
A data structure such as an array or a string can hold a number of bytes or characters in a storage medium. In programming, arrays store multiple values of the same type, while strings specifically hold sequences of characters. Additionally, files on disk or in memory can also serve as storage for bytes and characters, enabling data persistence and retrieval.
One byte is made up of 8 bits, and each bit can store 1 character. Therefore, 8 Bytes can store 64 Characters.
A stick of 512 megabytes of RAM can hold about 512 megabytes of data. It cannot, however, store it for long because it is volatile and is not designed to store data.
The number of bytes required to store a number in binary depends on the size of the number and the data type used. For instance, an 8-bit byte can store values from 0 to 255 (or -128 to 127 if signed). Larger numbers require more bytes: a 16-bit integer uses 2 bytes, a 32-bit integer uses 4 bytes, and a 64-bit integer uses 8 bytes. Thus, the number of bytes needed corresponds to the number of bits needed for the binary representation of the number.
The word: microprocessors, is 15 characters long, and would need a minimum of 15 bytes to store as ASCII. Some systems may need additional bytes to indicate that text is stored there, or how long the text field is, though.
