3.   
4.   
5. public class Test {  
6. public static void main(String[] args) {  
7. ExpressionParser parser = new SpelExpressionParser();  
8.   
9. //arithmetic operator  
10. System.out.println(parser.parseExpression("'Welcome SPEL'+'!'").getValue());  
11. System.out.println(parser.parseExpression("10 * 10/2").getValue());  
12. System.out.println(parser.parseExpression("'Today is: '+ new java.util.Date()").getValue());  
13.   
14. //logical operator  
15. System.out.println(parser.parseExpression("true and true").getValue());  
16.
