## Quick Start

### Prerequisites

- Java 21 or higher
- Maven 3.6 or higher

### Installation

Add the following dependency to your `pom.xml`:

        assertEquals("3", true, StringUtil.isNotBlank("a"));
        assertEquals("4", true, StringUtil.isNotBlank(" a "));
    }

    /**
     * @throws Exception
     */
    @Test
    public void testContains() throws Exception {
        assertEquals("1", true, StringUtil.contains("a", 'a'));
        assertEquals("2", true, StringUtil.contains("abc", 'b'));
        assertEquals("3", false, StringUtil.contains("abc", 'd'));
