Question

Import java.util.Random;

public class Matrix
{
private int[][] matrix;
// A constructor that initializes a matrix with random values
public Matrix(int rows, int cols, int maxRand)
{
// Creating a new 2D array with the specified number of rows and columns
int[][] mVals = new int[rows][cols];
// Creating a new Random object
Random rand = new Random();
// Filling the matrix with random values
for (int i = 0; i < rows; i++)
{
for (int j = 0; j < cols; j++)
{
mVals[i][j] = rand.nextInt(maxRand);
}
}
// Setting the matrix values using the helper method
setMatrixVals(mVals);
}

Answer 1

The question involves Java programming, focusing on initializing a matrix with random values using the Random class.

Step-by-step explanation:

The question provided relates to Computers and Technology, specifically programming with Java. The student is provided with a code snippet, which defines a Java class Matrix that initializes a matrix with random values.

The provided code creates a new 2D integer array with specified dimensions, fills it with random numbers (with the maximum random number not exceeding a specified value), and sets this as the matrix for the Matrix class. The process utilizes the Random class from the Java API to generate random numbers.
