How to convert a String to lowercase in Java

In this blog post, I will be explaining how you can convert a String to lowercase in Java. Consider the following code snippet:

 

</pre>package learnjava.strings;public class StringLowerCaseDemo {public static void main(String[] args) {String str = "Hello World";str = str.toLowerCase();System.out.println(str);}}<pre>

 

There is a String.toLowerCase method. This converts the String object on which it is invoked to lowercase and returns the converted String. So when you run the above code, you will get the following output:

hello world

How to check if a Date is before or after another Date

In this article, I will be covering how to can check if a date is before or after another Date. You can achieve this using the java.util.Date , java.util.Calendar classes or the new Java 8 java.util.LocalDate class. Using Date class Using the java.util.Date class, there are two ways to check if a date is before or after another Date. You can either use the before/after method or the compareTo method. Using Before/After The java.util.Date class has methods before() and after() . You can use these methods to compare two dates. These methods work as follows: The before method returns true if the date on which is it invoked is before the specified date, otherwise it returns false. The after method returns true if the date on which is it invoked is after the specified date, otherwise it returns false. The following code demonstrates this: SimpleDateFormat simpleDateFormat = new SimpleDateFormat("yyyy-MM-dd");Date date1 = simpleDateFormat.parse("2014-08-08");Date date2...

Java 11 String enhancements with examples

Java 11 has made some significant improvements to the String class. In this article, we will be exploring the Java 11 String enhancements strip Java 11 has added a new strip method to the String class. This method removes all the leading and trailing whitespaces in a String. Consider the following code: String input = " Hello World ";System.out.println(input);String output = input.strip();System.out.println(output); This code produces the following output: Hello WorldHello World In addition to strip , the String class also has a trim method which also removes all leading and trailing whitespaces. This method exists right from the early versions of Java and so has some limitations. Earlier, the ASCII character set was used. So, trim can only remove whitespaces represented by ASCII characters. However, later on Java adopted the Unicode character set.  Unicode has some additional characters that represent whitespace. The trim method cannot remove these whitespaces....

How to add Maven dependencies via Eclipse

In this blog post, I will be giving step by step directions on how you can add Maven dependencies via Eclipse. What is Maven Maven as you might probably know is a dependency management tool. It automatically downloads the necessary jar files for you.So you do not need to download the jar files and add them to your classpath explicitly. Maven uses a file named as pom.xml. This file has all the project configuration. The external jar files that are needed for the project need to be added as dependencies in this pom file. So for example, if you need Hibernate JAR files in your project, you will need to add Hibernate dependencies in the pom file. Maven then automatically downloads the jar files and adds them to the classpath. So let’s get started. Adding Maven Dependencies Via Eclipse Step 1 – Create your Maven project via Eclipse (Refer this post)   Step 2 – Right click on pom.xml. Click on Maven –> Add Depenency Step 3 – Enter group id, artifact id a...
