“cannot create directory `JAVA': Permission denied ” how to solve this issue?

Question

can anybody help me in solving this issue. I am new to Linux and here's problem:

gourab@gourab-RV509:/usr/share/java$ cd /
gourab@gourab-RV509:/$ cd usr
gourab@gourab-RV509:/usr$ mkdir JAVA
mkdir: cannot create directory `JAVA': Permission denied
gourab@gourab-RV509:/usr$ 

Answer 1

Instead of mkdir JAVA use sudo mkdir JAVA, then enter your password.

That should fix it.

However, you only really need to use one command instead of these two or three.

cd / 
cd usr 
sudo mkdir JAVA 

cd just changes the directory, no point in doing that. You can simply put the path of the file after mkdir, like so.

sudo mkdir /usr/JAVA

Answer 2

Permission denied means you have to be a superuser or root to create files/folder on a specific directory. So to create folder that needs a root permission, you need to simply add sudo before your command: sudo mkdir -p JAVA

Answer 3

In order to create a directory in any folder other than /home/username, where username is your account's username, you need to prepend mkdir with sudo, so create the folder like this:
sudo mkdir JAVA
