To convert the integer variable to the string variable, you need to use the explicit conversion or the functional method. In the below example, we are assigning an integer value to the variable $X.$x = 120 $x.GetType().NameNow when you check the data type of that variable, it will be Int32.To convert it into the string variable, first, we will use the explicit method by using a square bracket and data type to convert inside the brackets.[string]$x = 130 $x.GetType().NameThe data type of $x is the String.In the second method, you can use the PowerShell functional method ToString() to convert. For ... Read More
There are different data types exist for the variable like Byte, Int32, Float, String, etc. To get the variable type, we need to use the GetType() method.Example$x = 10 $x.GetType()OutputIsPublic IsSerial Name BaseType -------- -------- ---- -------- True True Int32 System.ValueTypeTo get only the variable datatype use Name property.$x.GetType().NameInt32
In Java 9, the module concept has introduced. It is a named, self-describing collection of code and data. The code can be organized as a set of packages containing types like java classes and interfaces, and data includes resources and other kinds of static information. A module contains a name, dependencies, and exported packages.Syntaxmodule com.tutorialspoint.mymodule { // some statements }In the below example, we can able to display all module names by using the ModuleLayer class.Examplepublic class AllModulesNamesTest { public static void main(String args[]) { ModuleLayer.boot().modules().forEach((module) -> { System.out.println(module.getName()); ...

JShell is a REPL tool introduced in Java 9 that allows us to execute Java code and getting results immediately. We can evaluate expressions or simple algorithms without creating a new project, compile or build it by using JShell. We can also execute expressions, use imports, define classes, methods, and variables. It is a part of Java 9 JDK but not JRE.We can start JShell session in command-prompt by simply typing jshell. We can use different commands: /exit to quit the JShell session, reset/reload JShell anytime by typing /reset, and /reload, /import to list the imports, etc.In the below example, we can print ...

Since Java 9, the JVM optimizes strings by using a new feature called Compact Strings. Instead of having a char[] array, a string can be represented as a byte[] array. We can use either UTF-16 or Latin-1 to produce either one or two bytes per character. If JVM detects the string contains only ISO-8859-1/Latin-1 characters, then string uses one byte per character internally.The string can be represented with a compact string or not is detected when the string is created. This feature has enabled by default and switches off using the -XX:-CompactStrings. It doesn't revert to a char[] implementation and stores all strings as ... Read More
Stack Walking API can provide a flexible mechanism to traverse and extract information from call stacks that allow us to filter and access frames in a lazy manner. StackWalker class is an entry point to Stack Walking API. The stack trace is a representation of a call stack at a certain point of time in which each element represents a method invocation. It contains all invocations from the start of a thread until the point it’s generated.In the below example, we can print/display all stack frames of the current thread by using StackWalker API.Exampleimport java.lang.StackWalker.StackFrame; import java.lang.reflect.Method; import java.util.List; import java.util.stream.Collectors; public ...

UAC (User account control ) is a windows IS security that enables a user to perform limited number of admin operations. Overall, it prevents normal users from performing specific actions that could pose a security risk to the system by requiring users to have admin-level permission. For security reasons enabling UAC to detect application installations and prompt for elevation to prevent regular user accounts from installing unauthorized software on clients is a best practice within Windows OS environments.In this tutorial, we shall investigate how to elevate the admin-level right from the end of a normal logged-in user by bypassing UAC ...

The Kali Linux is a Debian-derived Linux distribution designed for penetration testing and digital forensics adopted by both hackers and security professionals. It is highly probable that the user could not have been login owing to the forgotten password or not able to reset the password after installing it in the virtual environment or in the dual boot along with other OS. Hence, this article is designed to teach the aspiring penetration tester how to reset the Kali Linux password.The user is, typically stuck by confronting the following experience while not able to login to the Kali system as follows.But, ...
