Ternary Operator
The Spring Expression Language (SpEL ) is a simple and powerful expression language
which helps to query and manipulate objects at runtime.
The following example shows using ternary operator.
package com.bethecoder.tutorials.spring3.tests.spel; import org.springframework.expression.ExpressionParser; import org.springframework.expression.spel.standard.SpelExpressionParser; import org.springframework.expression.spel.support.StandardEvaluationContext; public class TernaryOperatorTest { /** * @param args */ public static void main ( String [] args ) { StandardEvaluationContext stdContext = new StandardEvaluationContext () ; ExpressionParser parser = new SpelExpressionParser () ; String value = null ; for ( int i = 1 ; i < 10 ; i ++ ) { stdContext.setVariable ( "num" , new Integer ( i )) ; value = parser.parseExpression ( "#num + ' is ' + (#num%2 == 0 ? 'even' : 'odd') " ) .getValue ( stdContext, String. class ) ; System.out.println ( value ) ; } } }
1 is odd
2 is even
3 is odd
4 is even
5 is odd
6 is even
7 is odd
8 is even
9 is odd
