In Java, constants can be defined using the final keyword. The value of a constant cannot be changed once it has been initialized.

Constants are typically named using uppercase letters, with underscores separating multiple words.

Constants can be defined at either the class level or the method level.

Example of defining constants at the class level:

public class MyClass {
    public static final int MAX_VALUE = 100;
    public static final String MESSAGE = "Hello, world!";
}

An example of defining constants at the method level:

public void myMethod() {
    final int MAX_VALUE = 100;
    final String MESSAGE = "Hello, world!";
}

It is important to note that constants defined at the class level can be accessed anywhere within the class, while constants defined at the method level can only be accessed within the method.
