Answer:

D zip code or postal code

Explanation:

Your zip code is only numbers, no text.

Your birth date can be written as August 26 2007 including text

The Zip Code should not use a domain of text. Hence, option (d) is correct, all others are not correct.

The United States Postal Service uses a ZIP Code as a postal code (USPS). The standard format included five digits and was unveiled on July 1, 1963.  An expanded ZIP+4 code, which had four additional digits after the hyphen and the five-digit ZIP Code to identify a more precise location, was first implemented in 1983.

The word ZIP stands for Zone Improvement Plan, and it was chosen to imply that when senders include the number in the postal address, mail moves more swiftly and effectively (or "zipping along"). The USPS initially filed a service mark application for the term "ZIP Code," however that application was later canceled.

This is the code of your question. Copy and paste the code in java IDE or compiler and run it and name the file as "abc1.java"

Moreover, method Mystery() takes two argument first and second and check whether number 'first' contains digit 'second' or not means when we call method with:

public class abc{

  public static boolean Mystery(int first,int second){

       boolean result=false;

       while(first>0){

           if(first%10==second)

               result=true;

           first=first/10;

       }

         return result;

   }

   public static void main(String[] args) {

           System.out.println(Mystery(252,2));

           System.out.println(Mystery(322,5));

       }

}

It will give output as:

True

False

Because when we call method with argument 252 and 2 then it will find remainder as 2 by dividing by 10 and check whether remainder 2 is equal to second argument or not if it equal then it will assign true in variable result. This process continue until first argument is greater than zero. It will true because number 252 contains digit 2.

Similarly it will do same thing with second call with argument 322 and 5 it will return false because number 322 does contains 5.

2) method zeroDigits takes one argument and count number of zero in a argument. when we run following code:

public class abc{

   public static int zeroDigits(int number){

       int count=0;

       do{

           if(number%10==0)

               count++;

           number=number/10;

       }while(number>0);

       return count;

   }

     public static void main(String[] args) {

           System.out.println(zeroDigits(500));

           System.out.println(zeroDigits(20));

       }

  }

It will give output as:

2

1

Because when we pass 500 as parameter then method counts the number of zeros bu finding remainder and check whether it is equal to 0 or not if it is equal then it increment variable count by 1. It will return 2 because 500 contains 2 zeros. Similarly, when we pass 20 as parameter then method returns 1 because 20 contains 1 zero.

This is the code of your question. Copy and paste the code in java IDE or compiler and run it and name the file as "abc.java" . I also provide the screenshot of output.

What is Port number?

An internet message or other network communication that arrives at a server can be redirected to a specific process by using the port number. All network-connected devices have standardized ports with a unique number installed.

A client submits a request of some kind to a server running on a different system, and the server reviews the request, acts on it in some way, and then might deliver some form of data back to the client. This fundamental concept is used by nearly all IP applications.

The list constructor is commonly used to find an index of array as it returns the array value for a particular index.

An array allows you to store multiple values with the same name and access them by using an index number.

A block of memory known as an array is used to store a group of identically typed data objects (also known as elements). When you need to keep track of numerous identical data elements but don't need to name them all, arrays come in handy. The position of an item in the array is instead indicated by the array name and a number (referred to as an index). You are able to create arrays of ints, doubles, Strings, and even custom classes like Students.

An index can be used to store a value in an array   A locker number is similar to an array index. It makes it easier for you to locate a specific location to keep and get items. Using an index, you can retrieve or add a value from or to an array.

Most programming languages count elements in lists and arrays starting at index 0, so the first element in an array is at index 0. An integer that designates a spot in an array is called an array index. The first character is at index 0, which is similar to how Strings are indexed in Java. In Java, arrays start the index at 0 not 1.

For example, if we want to make an array with 5 elements of type int the the following displays the indexes and values it:

index    0    1    2    3    4    5
