Java defined int as a 32-bit number because that is generally large enough to hold the information you need.
The size of an int in C may actually have either 16 or 32 bits, depending on the implementation. Basically, the specifications for any C implementation in UNIX must have 32-bit ints, while the ISO C standard only requires 16-bit ints. The stdint.h and limits.h files exist exactly because not all implementations are the same, and these files will define the min/max values of the integral types.

∙ 15y agoCharacters in C are ASCII characters. There are only 256 different characters in the ASCII character set, and so 8-bits are enough to store this data.
Characters in Java are 16-bit Unicode characters (65536 different characters), so twice as much storage is needed to store the extra characters.

What are the only types in Java that are not classes?
The non-class Java data types are primitives: * byte * short * int * long * float * double * boolean * char
What are java kaywords?
if ,while,do , int ,float, for,switch,else,
What is the memory size of integer pointer?
for C: sizeof (int), often 2 or 4 bytefor Java: 4 byte
How many types are there in java?
The two basic data types in Java are primitives and objects. Primitives: byte, char, short, int, long, float, double, boolean Objects: Everything else.
What are the nine basic data types?
Byte Short Int Long Float Double Char Bool String
How integer classified in java?
int short byte long
What is java int?
This groups includes byte,short,int and long.Integer data type is used for storing integer values.The size of the int is 32 bit.The range of the int is -2,147,483,648 to 2,147,483,648
What are the only types in Java that are not classes?
The non-class Java data types are primitives: * byte * short * int * long * float * double * boolean * char
How do you write a function which takes 2 arguments - a byte and a field in the byte and returns the value of?
bool F1(int byte,int pos) { return(byte & 1<<pos) } //pos -> position in the field // say byte is b1011 and pos is 2 then it will return value 0
Eight basic data types used in java?
char, boolean, byte, short, int, long, double, or float
What are java kaywords?
if ,while,do , int ,float, for,switch,else,
What is the memory size of integer pointer?
for C: sizeof (int), often 2 or 4 bytefor Java: 4 byte
What are fundamental data types in java?
Assuming by "fundamental" you mean the primitive data types: boolean, byte, char, short, int, long, float, and double
What is meant by wrapper classes?
Java has several "primitive" types (byte, short, int, float, double, boolean, char). Wrapper classes refer to the classes which "wrap up" each of these. For example, the Byte class contains a byte primitive and the methods to modify the class.
Why char consumes 2 bytes in java and int consumes 4 bytes in java?
in java, char consumes two bytes because it uses unicode instead of ascii. and int takes 4 bytes because 32-bit no will be taken
Write the program for two matrix adds in java?
