package com.bethecoder.tutorials.jodd.utils;

import jodd.util.StringUtil;

public class StringNotBlankTest {

  /**
   @param args
   */
  public static void main(String[] args) {
    System.out.println(StringUtil.isNotBlank(null));
    System.out.println(StringUtil.isNotBlank(""));
    System.out.println(StringUtil.isNotBlank("  "));
    System.out.println(StringUtil.isNotBlank("ABCD"));
  }
