Please I need help analyzing this piece of code.

package com.snhu.Module21;

import org.springframework.boot.SpringApplication;

import org.springframework.boot.autoconfigure.SpringBootApplication; import org.springframework.expression.Expression; import org.springframework.expression.ExpressionParser; import org.springframework.expression.spel.standard.SpelExpressionParser;

@SpringBootApplication public class Application {

public static void main(String[] args) { ExpressionParser parser = new SpelExpressionParser(); Expression exp = parser.parseExpression("'Hello World'"); String message = (String) exp.getValue(); System.out.println(message); SpringApplication.run(Application.class, args); }

}
