Answer:

The delimiter use is "::".

Explanation:

The Java inbuilt String.split( ) function is use to split a String into an array of String.

The split( ) takes delimiter as arguments/parameter which determines at which point the string is to be broken down into different part/token.

From the above code snippet;

Each line in the file a.txt that is not null is splitted using the statement below:

String[ ] v = line.split("::");

The line is splitted using "::" as delimiter and the resulting array is then assigned to the variable 'v'.

For instance, a line in the file could take the form:

John::Smith::Music

When it is splitted,

String lname = John;

because lname make reference to index 0 of the array.

String fname = Smith;

because fname make reference to index 1 of the array.

String dept = Music;

and dept make reference to index 2 of the array.

Everybody at a company is assigned a unique 9 digit ID. How many unique IDs exist?
Brut [27]
If you include all zeroes, then it should be 1,000,000,000. Otherwise it’s 999,999,999.

Think of how between 0-9 theres 10 numbers, and use that logic towards 000000000-999999999

Write a C++ programthat reads in the side of a square and prints out a pattern on$
AnnZ [28]

Answer:

#include<iostream>

using namespace std;

//main function

int main(){

   //initialize the variables

   int side;

   //print the message

   cout<<"Please enter the side of square: ";

   cin>>side;  //read the vale and store in the variable.

   // for loop

   for(int i=1;i<=side;i++){  //lop for rows

       for(int j=1;j<=side;j++){   //loop for column

           cout<<"$";  //print the '*'

       }

       cout<<endl;

   }

}

Explanation:

Create the main function and declare the variable side.

print the message on the screen for the user and then store value enter by the user on the variable side.

take the nested for loop for print the pattern.

nested for loop means, loop inside another loop it is used for print the pattern having rows and columns.

the first loop updates the row number and the second the loop print the character '$' in the column-wise.

in the code,

if i = 1, for loop check the condition 1 <= 5 if the value of side is assume 5.

condition is true and the program moves to the second for loop and starts to print the character '$' five times after that, print the new line.

then, the above process repeat for different rows and finally, we get the pattern in square shape.

How to create json object from variables javascript
tino4ka555 [31]
Not entirely sure what you want to achieve, but consider this program:

var a = 'foo';
var b = 'bar';

var c = { first : a, second : b };

console.log(JSON.stringify(c, null, 4));

A json object c is constructed using the values from variables a and b. Is this what you mean?
