its java programming.

Exercise B:

Write a program, MatchingArray, that contains an array of five names and another array of five passwords(your choice). Your program should ask the user to enter a name and password. If the user enters the correct name with it\'s related password , Printout ..It\'s a match. If the user enters the wrong name/password (can be either or both), Print the message..It\'s not a match.

Note: In your array, first name should match with your first password. Second name should match with your second password...etc..

Solution

/*this program has been tested on eclipse */

import java.util.Scanner; //for using scanner
public class HelloWorld{

public static void main(String []args){
Scanner sc=new Scanner(System.in);
String usrname,pwd; //variable for storing the username and password //provided by the user
    String name_ary[]={\"jhon\",\"ram\",\"anurag\",\"gopal\",\"christina\"}; //initializing a name array containing 5 //names of my choice,you can change the names
String password_ary[]={\"#hello\",\"1234\",\"wifi12$\",\"forgetpassword\",\"12#abc$%\"}; //initializing a password //array containing 5 passwords of my //choice,you can change the passwords
System.out.println(\"Enter a name \"); //Asking the user to enter the username
       usrname=sc.next(); //storing the user entered username in the //variable usrname
System.out.println(\"Enter a password \"); //Asking the user to enter the password         
pwd=sc.next(); //storing the user entered password in the //variable pwd
int index=-1; //initializing a variable index
for(int i=0;i<name_ary.length;i++) //searching the user entered usrname in the //name_ary
{
if(usrname.equals(name_ary[i])) //if user entered usrname is available in //name_ary
{
index=i; //store the index of the found username in index
break;
}
}
if( index >= 0 && index < name_ary.length ) //if index is greater than 0 and less than // 5,it means user entered username is available in //name_ary
      
{
if(password_ary[index].equals(pwd)) //find the user entered password in //password_ary at the index
System.out.println(\"It\'s a match \"); //prints its a match
else
System.out.println(\"It\'s not a match \"); //prints its not a match
}
else
System.out.println(\"It\'s not a match \"); //prints its not a match
}
}
//end of program

**************OUTPUT***********
