Help on merging classes

Question

hi i have 3 classes, player, card, test
player class:
public class Player {
String name;
public String getName() {
return name;
public void setName(String playerName) {
name = playerName;
}card class:
import java.util.*;
public class card {
     public static int[][] createGridOfNumbers(int nRows, int nCols) {
     Random randomNumberGenerator = new Random();
     int[][] grid = new int[ nRows ][ nCols ];
     for (int nRow = 0; nRow < nRows; nRow++) {
     for (int nCol = 0; nCol < nCols; nCol++) {
     int nMinRandomNumber = nCol * 10 + 1;
     int nMaxRandomNumber = (nCol + 1) * 10;
int randomNumber = randomNumberGenerator.nextInt(nMaxRandomNumber - (nMinRandomNumber - 1)) + nMinRandomNumber;               
if (nRow > 0) {
boolean foundUniqueNumber = false;
do {
boolean isNumberInGrid = false;
for(int nCheckRow = 0; nCheckRow < nRow; nCheckRow++) {
  if(randomNumber == grid[ nCheckRow ][ nCol ]) {
                               isNumberInGrid = true;
break;
                                   if(isNumberInGrid) {
                                 randomNumber = randomNumberGenerator.nextInt(nMaxRandomNumber - (nMinRandomNumber - 1)) + nMinRandomNumber;
                                 foundUniqueNumber = false;
          } else {
                                 foundUniqueNumber = true;
     } while(!foundUniqueNumber);
     grid[ nRow ][ nCol ] = randomNumber;
          return grid;
     public static void displayGrid(int[][] grid) {
for (int nDash = 0; nDash < grid[ 0 ].length * 6; nDash++) {
             System.out.print("-");
          System.out.println();
          for (int nRow = 0; nRow < grid.length; nRow++) {
     for (int nCol = 0; nCol < grid[ 0 ].length; nCol++) {
          System.out.print("| ");
          if (grid[ nRow ][ nCol ] < 10) {
             System.out.print(" ");
     System.out.print(grid[ nRow ][ nCol ] + " |");
     System.out.println();
for (int nDash = 0; nDash < grid[ 0 ].length * 6; nDash++) {
             System.out.print("-");
     public static void main(String[] arg) {
          int[][] grid = createGridOfNumbers(4, 9);
          displayGrid(grid);
}test class:
public class test{
     public static void main(String[] args) {
String playerName;
     System.out.println("Welcome ty ");
     System.out.println("Please enter your name");
playerName = Console.readFromKeyboard();
            Player player = new Player();
            player.setName(playerName);
           System.out.println("Hello " + player.getName());
}i managed to get the player code working in the test class, but im not sure on how to move the card class into the test class. i tired using import but that didnt work, could someone advise me on a option for this.

Answer 1

well this is new code for the test class, the grid says that it cant be resolved, shouldnt the '.card' resolve that, or have i put it in wrong?
public class test{
     public static void main(String[] args) {
String playerName;
     System.out.println("Welcome ty ");
     System.out.println("Please enter your name");
playerName = Console.readFromKeyboard();
            Player player = new Player();
            player.setName(playerName);
           System.out.println("Hello " + player.getName());
             card.createGridOfNumbers(4, 9);
             card.displayGrid(grid);
}
