How to find symbolic link or soft link in Linux - ls + find command example

There are two ways you can find a symbolic link or soft link in UNIX based operating system like Linux, Solaris, BSD, or IBM AIX. The first way is by using the ls command in UNIX which displays files, directories, and links in any directory and the other way is by using UNIX find command which has the ability to search any kind of files e.g. file, directory, or link.

Can You Override Static Method in Java? Method Hiding

Can we override the static method in Java

This is one of the most popular Java interview questions. The answer to this question is No, you cannot override the static method in Java because the method overriding is based upon dynamic binding at runtime and static methods are bonded using static binding at compile time. This means static methods are resolved even before objects are created, that's why it's not possible to override static methods in Java. Though you can declare a method with the same name and method signature in the subclass which does look like you can override static methods in Java but in reality that is method hiding.
