Explanation:
the general structure of a for-each loop header is represented as :
for (type variable-name : array-or-collection) - On each iteration the next element can be accessed using the specified variable.
In other words it can be represented as:
for (type variable-name : array-or-collection)
{
//On each iteration the variable-name will contain the next value in the array or collection and this value can be referenced in the loop body using the variable-name.
}

Phishing
Explanation:
Phishing is a social engineering attack where users are asked to respond to an email or are directed to a website where they are requested to login with their personal credentials, such as passwords or credit card numbers.

A computer virus is a program that is installed without the permission or knowledge of the computer user.
It is designed to alter the computer's normal operations and can replicate itself to infect other files, programs, or media it can access. Computer viruses are malicious and often spread through infected files, emails, or downloads.
Once inside a computer system, they can cause various damages, such as corrupting data, stealing personal information, or disrupting the computer's functionality.
As they replicate, they can rapidly spread to other devices and networks, making them a significant threat to the security and integrity of computer systems worldwide.
Protecting against viruses requires robust antivirus software and cautious online behavior.
