5. Command to install Protractor globally is: npm install -g protractor [We use globally when need to execute Protractor from any directory of the system]
6. Execute command to check version of the installed Protractor: protractor --version
7. Install webdriver managet to run selenium server and command is: webdriver-manager update
8. To start the selenium server command is: webdriver-manager start
In next step let's check script execution:
9. Open command prompt and go to example folder of Protractor. [e.g; C:\Users\<username>\AppData\Roaming\npm\node_modules\protractor\example] Here, username is your window system's user.
10. Execute command to run script is: protractor conf.js

Note: If you are getting any error to run example then recheck followed steps.

if (length == 0) {
return false;
}

for (int i = 0; i < length; i++) {
char c = str.charAt(i);
if (c < '0' || c > '9') {
return false;
}
}
return true;
}

Generate Random Number

public static String generateRandomNumber() {
Calendar c = Calendar.getInstance();
String str = String.valueOf(c.get(Calendar.YEAR)) + String.valueOf(c.get(Calendar.MONTH)) + String.valueOf(c.get(Calendar.DAY_OF_MONTH)) + String.valueOf(c.get(Calendar.HOUR_OF_DAY)) + String.valueOf(c.get(Calendar.MINUTE)) + String.valueOf(c.get(Calendar.SECOND));
return str;
}
