Introduction

In this page you can find the example usage for org.apache.commons.lang.math NumberUtils toInt.

Prototype

public static int toInt(String str, int defaultValue)

Source Link

Document

Convert a String to an int, returning a default value if the conversion fails.

If the string is null, the default value is returned.

 NumberUtils.toInt(null, 1) = 1 NumberUtils.toInt("", 1)   = 1 NumberUtils.toInt("1", 0)  = 1

Usage

From source file:MainClass.java

public static void main(String[] args) {
    //Convert String to int. If value invalid, return default value.
    System.out.println("String to Int >>> " + NumberUtils.toInt("ABCD", 77));

}

From source file:com.cloud.utils.NumbersUtil.java

public static int parseInt(String s, int defaultValue) {
    return NumberUtils.toInt(s, defaultValue);
}

    assertTrue(xml.endsWith("</stud:studies>"));

    String xml2 = new XsltTransformer().toText(xmlStudyDetailsResult(), "/xslt/c2a_generic_response.xslt");
    String s = StringUtils.trim(xml2);
    int i = NumberUtils.toInt(s, -99);
    assertEquals(1, i);/*from  w  ww.j  a v a2s  .c o m*/
