It's used QR codes in a way that is so useful that it… QR (Quick Response) code is the trademark name for the two dimensional barcode system. It was originally invented in 1994 by Denso Wave, a Toyota subsidiary, as a way to track vehicles as they were assembled, and to scan components at high speeds.

QR codes were created to make a way for people to easily scan codes to get to a website. So you could scan (example) a movie poster to go to the website that has advertisements and tickets.

Kazeer [188]

Answer:

import java.util.*;

public class Main

{

public static void main(String[] args) {

    Random r = new Random();

    int[][] numbers = new int[10][15];

   

    for (int i=0; i<10; i++){

        for (int j=0; j<15; j++){

            numbers[i][j] = new Random().nextInt(101);

        }

    }

   

    for (int i=0; i<10; i++){

        for (int j=0; j<15; j++){

            System.out.print(numbers[i][j] + " ");

        }

        System.out.println();

    }

   

    findmax(numbers);

}

public static void findmax(int[][] numbers){

    int max = numbers[0][0];

   

    for (int i=0; i<10; i++){

        for (int j=0; j<15; j++){

            if(numbers[i][j] > max)

                max = numbers[i][j];

        }

    }

    System.out.println("The max is " + max);

}

}

Explanation:

*The code is in Java.

Create a function called findmax() that takes one parameter, numbers array

Inside the function:

Initialize the max as first number in the array

Create a nested for loop that iterates through the array. Inside the second for loop, check if a number is greater than the max. If it is set it as the new max

When the loop is done, print the max

Inside the main:

Initialize a 2D array called numbers

Create a nested for loop that sets the random numbers to the numbers array. Note that to generate random integers, nextInt() function in the Random class is used

Create another nested for loop that displays the content of the numbers array

Call the findmax() function passing the numbers array as a parameter

Fill in this function that takes three parameters, two Strings and an int. 4- // Write some test function calls here! The String
zimovet [89]

Answer:

The function in Java is as follows:

public static void printMessage(String lineOne, String lineTwo, int lines){

       for(int i = 1;i<=lines;i++){

           if(i%2 == 1){

               System.out.println(lineOne);

           }

           else{

               System.out.println(lineTwo);

           }

       }

   }

Explanation:

This defines the function

public static void printMessage(String lineOne, String lineTwo, int lines){

This iterates through the number of lines

       for(int i = 1;i<=lines;i++){

String lineOne is printed on odd lines i.e. 1,3,5....

      if(i%2 == 1){

               System.out.println(lineOne);

           }

String lineTwo is printed on even lines i.e. 2,4,6....

           else{

               System.out.println(lineTwo);

           }

       }

   }

To call the function from main, use:

printMessage("Hi", "Karel", 5);
