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 creating single and multi dimentional arrays using SpEL.

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

import java.util.Arrays;

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

public class ArrayTest {

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

    ExpressionParser parser = new SpelExpressionParser();

    int [] nums = (int[])parser.parseExpression("new int [6]").getValue();
    System.out.println(Arrays.toString(nums));

    nums = (int[])parser.parseExpression("new int [] {1, 2, 3, 4, 5, 6}").getValue();
    System.out.println(Arrays.toString(nums));
    
    int [][] nums2 = (int[][])parser.parseExpression("new int [6][4]").getValue();
    System.out.println(nums2);
    
  }

}
   

It gives the following output,
[0, 0, 0, 0, 0, 0]
[1, 2, 3, 4, 5, 6]
[[I@11d0a4f


                    Print
