package com.bethecoder.tutorials.spring3.tests.spel;

import org.springframework.expression.Expression;
import org.springframework.expression.ExpressionParser;
import org.springframework.expression.spel.standard.SpelExpressionParser;

public class BooleanTest {

  /**
   @param args
   */
  public static void main(String[] args) {

    ExpressionParser parser = new SpelExpressionParser();
    Expression exp = parser.parseExpression("2 > 0");
    Boolean value = exp.getValue(Boolean.class);
    System.out.println(value);

    exp = parser.parseExpression("2 > 6");
    value = exp.getValue(Boolean.class);
    System.out.println(value);
    
    exp = parser.parseExpression("'BTC' == 'BTC'");
    value = exp.getValue(Boolean.class);
    System.out.println(value);
  }

}
   

It gives the following output,
true
false
true


                    Print
