What Is The Default Value Of Long In Java?

The long has a minimum value of -2 63 and a maximum value of 2 63 -1, with a minimum value of -2 63 and a maximum value of 2 63 -1. Long may now be represented as an unsigned 64-bit long in Java 8, with a minimum value of 0 and a maximum value of 2 64 -1; this is the first time this has happened. The default value for this variable is 0L.

Default Values

Data Type Default Value (for fields)
long 0L
float 0.0f
double 0.0d
char ‘\u0000’

What is the maximum value of long data type in Java?

There is a difference between the minimum and maximum values of the signed long. The least value is -263, while the highest value is 263–1. For unsigned 64-bit longs with a minimum value of 0 and a maximum value of 264–1, the long data type can be used in Java SE 8 and subsequent versions of the language.

What is an object of type long in Java?

An object of type Long includes a single field of type long, which is the type of the object. This class also has various methods for converting from and to strings, as well as additional constants and methods that are important when dealing with strings.

What is long default value?

Default Values are listed in Table 3.12.

Type Default
sbyte, byte, short, ushort, int, uint, long, ulong
char ‘\x0000’
float 0.0f
double 0.0d

What is a long value in Java?

In Java, the long data type is a numeric data type. This is often referred to as the primitive type. The long type requires 64 bits of available memory. There is a limit to the amount of data that a long type variable may store: 9,223,372,036,854,775,807L. There is a minimum value of -9,223,372,036,854,775,808L in this equation.

What is long value?

Long: The long data type is a signed two’s complement integer with a length of 64 bits. -9,223,372,036,854,775,808 is the lowest possible value, and 9,223,372,036,854,775,807 is the highest possible value (inclusive).

Is double longer than long?

According to an article on Microsoft’s Developer Network, the double data type has a range of ‘-1.79769313486232e308 1.79769313486232e308’ (negative 1.79769313486232e308). The long data type, on the other hand, only has a range of ‘-9,223,372,036,854,775,808’.

What is the size of Long variable?

Data Types and Sizes

Type Name 32–bit Size 64–bit Size
short 2 bytes 2 bytes
int 4 bytes 4 bytes
long 4 bytes 8 bytes
long long 8 bytes 8 bytes

How long is a long Java?

Primitive Data Types

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

Is Long same as int?

The long data type is bigger than the int data type. The difference between an int and a long is that an int has a width of 32 bits whereas a long has a width of 64 bits.

Should I use long or int?

When developing code, if a value in the medium range is required, the int type can be used. However, when the output generated by any expression is greater, or when larger values are required for computation, the long type variable must be used to store the values in the long range.

What is final long in Java?

When creating an entity in Java, the final keyword can be used to complete the declaration. If the final keyword is used, it indicates that the value cannot be changed in the future. This entity can take the form of a variable, a class, or a method, but it is not restricted to these. Variables, parameters, methods, and classes are the final step.

What is long class in Java?

The Long class contains an object that has a value of the primitive type long. An object of type Long includes a single field of type long, which is the type of the object. This class also has various methods for converting from and to strings, as well as additional constants and methods that are important when dealing with strings.

Can Java long have decimals?

Long variables may store values ranging from -9,223,372,036,854,775,808 to 9,223,372,036,854,775,807, with the highest value being 9. Long operations are slightly slower than Integer operations, although they are not significantly slower. Use the Decimal Data Type if you want even greater values than those provided by the Floating Point Data Type.

What is difference between long and long in Java?

Long is a type of person. Long is a basic form of expression. That is, Long can be null, but Long cannot be null. In contrast to long, which can go anyplace that accepts an Object, long cannot (since it isn’t a class, it doesn’t derive from Object).

What is the default value of INT in Java?

Now, let’s put together a java application that demonstrates how the default value of int is calculated in Java. The preceding software clearly demonstrates that the default value of 0 is assigned to unassigned int data type variables in Java by the compiler. There is no limit to the number of such variables that may be added and their values shown; the outcome will always be 0.
