## What is a long class in Java?

Long class is **a wrapper class for the primitive type long** which contains several methods to effectively deal with a long value like converting it to a string representation, and vice-versa. An object of Long class can hold a single long value.

## What can long hold in Java?

A Java long data type can hold **the largest integer values**. It takes up 64 bits of memory and accepts a range from -9,223,372,036,854,775,808 to 9,223,372,036,854,775,807. It’s useful for storing numbers that outgrow the integer data type.

## What is long Max_value Java?

long: The long data type is a 64-bit signed two’s complement integer. It has a minimum value of -9,223,372,036,854,775,808 and a maximum value of **9,223,372,036,854,775,807 (inclusive)**.

## Is Long a class in Java?

The Long class **wraps a value of the primitive type long in an object**. An object of type Long contains a single field whose type is long . In addition, this class provides several methods for converting a long to a String and a String to a long , as well as other constants and methods useful when dealing with a long .

## Is long a Java type?

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.

## Should I use long or long in Java?

Always use the simplest thing that works, so if you need any of the features of Long , **use Long otherwise use long** .

## What is long in Java example?

The long (primitive type) and Long class:

The long is a **numeric data type** in Java. … 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 bigger than long in Java?

The largest integer number that a long type can represent is 9223372036854775807. If we deal with even larger numbers, we have to use the java.

…

Integers.

Type | Size | Range |
---|---|---|

char | 16 bits | 0 to 65,535 |

int | 32 bits | -2,147,483,648 to 2,147,483,647 |

long | 64 bits | -9,223,372,036,854,775,808 to 9,223,372,036,854,775,807 |

## IS 10/9 long or int?

Yes it is (assuming that you are adopting the notation 10^9 to mean 1e9 – ^ is the XOR operator in C, and 10^9 is 3 ). An unsigned long long has to be capable of storing a number between 0 and 2^{64} – 1.

## Which is bigger double or long Java?

3 Answers. If you are storing integers, **use Long** . Your statement that “Advantage of Using Double is that it gives a more wider range for storing Whole Numbers” is incorrect. Both are 64 bits long, but double has to use some bits for the exponent, leaving fewer bits to represent the magnitude.

## How many digits is a long Java?

long 8 bytes -9,223,372,036,854,775,808 to 9,223,372,036,854,775,80. float 4 bytes **7 decimal** digits.

## What is Maxvalue in Java?

Integer. MAX_VALUE represents the maximum positive integer value that can be represented in 32 bits (i.e., **2147483647** ). This means that no number of type Integer that is greater than 2147483647 can exist in Java.

## What is difference between long and long in Java?

A Long is a class, or a reference type, defined in the standard library. It stores a reference to an object containing a value (a “box”). A long on the other hand, is a primitive type and part of the language itself. … We say that Long is the wrapper type for long , and objects of type Long are boxed **values**.
