what is the meaning of public static final string SOME_VARIABLE = "variable text"

what is the meaning of public static final string SOME_VARIABLE = "variable text"

final indicates that the value of the variable won't change - in other words, a variable who's value can't be modified after it is declared.

Use public final static String when you want to create a String that:

belongs to the class (static: no instance necessary to use it), and that
won't change (final), for instance when you want to define a String constant that will be available to all instances of the class, and to other objects using the class.


Similarly:

public static final int ERROR_CODE = 54654;
It isn't required to use final, but it keeps a constant from being changed inadvertently during program execution, and serves as an indicator that the variable is a constant.

Even if the constant will only be used - read - in the current class and/or in only one place, it's good practice to declare all constants as final: it's clearer, and during the lifetime of the code the constant may end up being used in more than one place.

Also, you may access the value of a public static string w/o having an instance of a class.

static means that the object will only be created once, and does not have an instance object containing it. The way you have written is best used when you have something that is common for all objects of the class and will never change. It even could be used without creating an object at all.

Usually it's best to use final when you expect it to be final so that the compiler will enforce that rule and you know for sure. static ensures that you don't waste memory creating many of the same thing if it will be the same value for all objects.

public makes it accessible across other classes.

package org.junit does not exist

package org.junit does not exist

Your Test class might be located in src/main/java.
Also the value of the "scope" element in the POM for JUnit was "test", although that is how it is supposed to be.
The problem was that You had been sloppy when creating the test class in Eclipse that is
resulting in it being created in src/main/java insted of src/test/java.

So put your .java class in src/test/java


And in pom.xml just add  <scope>test</scope> for junit dependency if it is already existed.


<dependency>
  <groupId>junit</groupId>
  <artifactId>junit</artifactId>
  <version>4.11</version>
  <scope>test</scope>
</dependency>

ANDROID_HOME not set appium java

Where the Android-SDK is installed depends on how you installed it. If you downloaded the SDK through their website and then dragged/dropped the Application to your Applications folder, it's most likely in /Applications/ADT/sdk (as it is in your case).

If you installed it using Homebrew (brew install android-sdk), then it's located here:

/usr/yourusername/android-sdks

env | grep ANDROID_HOME on the terminal that is working. If the file is already existed This should give something like

ANDROID_HOME=/usr/yourusername/android-sdks

If not they do changes on Bash file

Type below command to check whether bash_profile existed or not

ls -1 ~/.bash_profile

 

If it is not existed then it message throws as “No such file or directory”

touch ~/.bash_profile 

now open .bash_profile, if you dont have one just create one

vi ~/.bash_profile

Add the following:

esc + i   it allow to enter data into vim editor

#set ANDROID_HOME

ANDROID_HOME=/usr/yourusername/android-sdks

export ANDROID_HOME

Once you have this set, you need to add this to the PATH environment variable

export PATH=$PATH:$ANDROID_HOME/tools:$ANDROID_HOME/platform-tools

Now save the file  by pressing below commands esc + :wq  

And after that to execute bash file 

 source ~/.bash_profile

 

 Now if you type this command it should show path

 

 echo $ANDROID_HOME
