The long is
a numeric data type in Java
. This is also the primitive type. The long type takes 64 bits of memory. The maximum value that a long type variable can store is 9,223,372,036,854,775,807L. The minimum value is -9,223,372,036,854,775,808L.
What is long in Java example?
long: The long data type is
a 64-bit two’s complement integer
. The signed long has a minimum value of -2
63
and a maximum value of 2
63
-1. In Java SE 8 and later, you can use the long data type to represent an unsigned 64-bit long, which has a minimum value of 0 and a maximum value of 2
64
-1.
What is the use of long in Java?
The Java long keyword is a primitive data type. It is used
to declare variables
. It can also be used with methods. It can hold a 64-bit two’s complement integer.
What is difference between long and int?
The basic difference between the type int and long is of their width where int is 32 bit, and
long is 64 bits
. … In Java, the range of type int is from –2,147,483,648 to 2,147,483,647 whereas, the range of type long is from –9,223,372,036,854,775,808 to 9,223,372,036,854,775,807 which is very much greater than type int.
Is long an int?
An int is a 32-bit integer; a
long is a 64-bit integer
. … int and long are primitive types, while Integer and Long are objects.
What is long example?
Frequency: The definition of long is an extended distance or an extended period of time. An example of long is
a 100 mile road
. An example of long is a 4-hour movie. … A mile long; an hour long.
How is long declared in Java?
Using the long Java data type example
Just like the int type variables, the long type is declared. You may assign a value at the time of declaration or after that. As mentioned earlier, the long type takes
64 bits of memory
, so may store much larger value than int type, that takes 32 bits.
What is the limit of long in Java?
| Data Type Size Description | byte 1 byte Stores whole numbers from -128 to 127 | short 2 bytes Stores whole numbers from -32,768 to 32,767 | int 4 bytes Stores whole numbers from -2,147,483,648 to 2,147,483,647 | long 8 bytes Stores whole numbers from -9,223,372,036,854,775,808 to 9,223,372,036,854,775,807 |

What is difference between == equals () and compareTo () method?
compareTo:
Compares two strings lexicographically
. equals: Compares this string to the specified object. compareTo compares two strings by their characters (at same index) and returns an integer (positive or negative) accordingly. equals() can be more efficient then compareTo().
Can Java long be negative?
The reason why Java doesn’t throw an exception and you receive negative numbers has
to do with the way numbers are stored
. For a long primitive the first byte is used for indicating the sign of the number (0 -> positive, 1 -> negative), while the rest are used for the numeric value. This means that Long.
Why do we use long int?
Sometimes, the range of long is the same as int (32-bit systems; 64-bit Windows); then the main reason for using long or int is
to match the interface to a particular API
(because the types are still distinct, even if they support the same range).
Should I use long or int?
The typical thing to do is to
just use int if you don’t care about the size of the integer
. If you need a 64-bit integer, then you use long . If you’re trying to use less memory and int is far more than you need, then you use byte or short .
Is Long a datatype in C?
Main types. The C language provides the four basic arithmetic type specifiers char, int, float and double, and the modifiers signed, unsigned, short, and long. … It is
an integer type
. Actual type can be either signed or unsigned.
How do you convert long to int?
- public class LongToIntExample2{
- public static void main(String args[]){
- Long l= new Long(10);
- int i=l.intValue();
- System.out.println(i);
- }}
Is Long bigger than int Java?
When we want to store a value bigger than int range, we should use
long type
. … (in C, long is a data modifier but in Java long is a data type). When using a constant bigger than int range, we should suffix it with ‘l’ or ‘L’ to indicate it to be a long value.
What is the maximum value of int?
| Constant Meaning Value | INT_MIN Minimum value for a variable of type int . -2147483648 | INT_MAX Maximum value for a variable of type int . 2147483647 | UINT_MAX Maximum value for a variable of type unsigned int . 4294967295 (0xffffffff) | LONG_MIN Minimum value for a variable of type long . -2147483648 |
