What does values ​​mean in java

values() is a static method of the enumeration type in Java, used to obtain an array containing all the constants of the enumeration, arranged in the order of declaration. Specifically: Returns a typed array containing the enumeration constants. The elements in the array are arranged in the order in which the enumeration is declared. Methods are static and can be called without creating an instance. There is only one values() array per enumeration type. The values ​​of enumeration constants cannot be modified.

The meaning of Values ​​in Java

In Java, values() is a Static method for obtaining a constant array of enumeration type. It is an important part of the enumeration type and is used to access the fixed values ​​defined by the enumeration.

Function

##values() The method returns an array containing all the constants of the enumeration, and its type is an array of the enumeration type. The elements in the array are arranged in the order in which the enumeration is declared.

Syntax

public static T[] values()

Where:

• T is the type parameter of the enumeration type.

Returns

An array containing all the constants of the enumeration.

Example

Consider the following enumeration type:

public enum Season {
    SPRING, SUMMER, FALL, WINTER
}

We can get the enumeration using the

values() method All constants in the example:

Season[] seasons = Season.values();

Now, the

seasons array will contain the following elements:

<code>[SPRING, SUMMER, FALL, WINTER]</code>

Notes

• values() The method is static and therefore can be called directly from the class level without creating an instance of the class.
For each enumeration type, only a single
• values() array exists.
The constant values ​​of the enumeration are not modifiable, which means that the constants returned in the
• values() array cannot be modified.
