The white-space characters include space, tab, line-feed, carriage-return, new line, form-feed. Let’s see the code snippet below: package org.kodejava.lang; import java.util.Arrays; public class SplitStringMultiSpaces { public static void main(String[] args) […]
In this example you’ll learn how to clear or reset the content of an array. We can use the java.util.Arrays.fill() method to replace to content of each element in the array.

This example show you how to validate input when using java.util.Scanner. To validate input the Scanner class provides some hasNextXXX() method that can be use to validate input. For example if we want to check whether the input is a valid integer we can use the hasNextInt() method. In the code snippet below will demonstrate […]
This example show you how to use the DosFileAttributes class to get file attribute that support DOS file system. This class extends the BasicFileAttributes class. Using the DosFileAttributes class we can read file attributes using isArchive(), isHidden(), isReadOnly() and isSystem() methods. Let’s see the code snippet below: package org.kodejava.io; import java.nio.file.Files; import java.nio.file.Path; import java.nio.file.Paths; […]
This code snippet show you an example on how to set the value of file attributes. Here we will set the DosFileAttributes. To set the value of file attributes we use the Files.setAttributes() method. To set DosFileAttributes we can use the following attributes: "dos:archive", "dos:hidden", "dos:readonly" and "dos:system". For details let’s see the code snippet […]
