Static constant<\/strong>.<\/p>\n<p>A static constant is a variable that is declared with the <code>static<\/code> keyword and the <code>final<\/code> keyword. It is initialized once, at compile time, and its value cannot be changed after it has been initialized.<\/p>\n<p>A constant variable is a variable that is declared with the <code>final<\/code> keyword. It can be initialized at compile time or at runtime.<\/p>\n<p>A class variable is a variable that is declared inside a class but outside of any methods or constructors. It is shared by all instances of the class.<\/p>\n<p>A named constant is a variable that is declared with the <code>const<\/code> keyword. It is similar to a static constant, but it can only be used in the file in which it is declared.<\/p>\n<p>Here is an example of a static constant:<\/p>\n<p>&#8220;`<br \/>\npublic class MyClass {<\/p>\n<pre><code>private static final int CONSTANT = 10;\n\npublic static void main(String[] args) {\n    System.out.println(CONSTANT); \/\/ prints 10\n}\n<\/code><\/pre>\n<p>}<br \/>\n&#8220;`<\/p>\n<p>In this example, the <code>CONSTANT<\/code> variable is a static constant. It is initialized to the value 10 at compile time, and its value cannot be changed after it has been initialized.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>[amp_mcq option1=&#8221;Constant variable&#8221;
