I am having issues passing arrays to my methods it is getting an error of "cannot find symbol"but I am confused on how these 2D arrays should be passed in the method "how many" This program is supposed to prompt for 18 ints and placed into 2 2D arrays then return of they are equal or not. Am I supposed to place the array names in boolean equalOrNot = howmany(FirstArray, SecondArray);
or what?
import java.util.Scanner;
public class n01092281
{
public static void main (String[] args)
{
Scanner input = new Scanner (System.in);
int FirstArray [][] = new int[3][3];
int SecondArray [][] = new int[3][3];
System.out.print("Enter List1 and List2 (18 numbers): ");
for (int row = 0; row < FirstArray.length; row++)
{
for(int column = 0; column < FirstArray[row].length; column++)
{
FirstArray[row][column] = input.nextInt();
}
}
for (int row = 0; row < SecondArray.length; row++)
{
for(int column = 0; column < SecondArray[row].length; column++)
{
SecondArray[row][column] = input.nextInt();
}
}
boolean equalOrNot = howmany(FirstArray, SecondArray);
if (equalOrNot)
{
System.out.println("Two Arrays Are Equal");
}
else
{
System.out.println("Two Arrays Are Not equal");
}
}
public class strict
{
public boolean howmany(int[][] FirstArray, int[][] SecondArray)
{
boolean equalOrNot = true;
if(FirstArray.length == SecondArray.length)
{
for (int i = 0; i < FirstArray.length; i++)
{
if(FirstArray[i] != SecondArray[i])
{
equalOrNot = false;
}
}
}
else
{
equalOrNot = false;
}
}
}
}
Few points that could help over the shared code :
Please follow better-naming conventions.
public boolean howmany
does not have a return statement to actually return
a boolean value, possibly add at the end of the method :
return equalOrNot;
The comparison should also be over the number of columns of the array and the condition should become somewhat like :
if(FirstArray[i][j] != SecondArray[i][j])
You cannot call howmany
method currently from a static context even considering Strict
to be an inner class(with those inappropriately matched braces).
