To get the package name of a class we can use the getClass().getPackage() method of the inspected object. package org.kodejava.lang; import java.util.Date; public class GetPackageName { public static void main(String[] args) { // Create an instance of Date class, and then obtain the class package // name. Date date = new Date(); Package pack = […]
To get the super class of an object we can call the object’s getClass() method. After getting the class type of the object we call the getSuperclass() method to get the superclass. Let’s see the code snippet below. package org.kodejava.lang; public class ObtainingSuperClass { public static void main(String[] args) { // Create an instance of […]
This code snippet uses the java.util.regex.Pattern.split() method to split-up input string separated by commas or whitespaces (spaces, tabs, new lines, carriage returns, form feeds). package org.kodejava.regex; import java.util.regex.Pattern; public class RegexSplitExample { public static void main(String[] args) { // Pattern for finding commas, whitespaces (spaces, tabs, new lines, // carriage returns, form feeds). String pattern […]
