My 3D array in java is not printing out correctly...why?

Here's the code:

import java.util.Scanner;

public class Array

       int sum=0;
       switch(x)
       {
           case 1:
               System.out.println("How many integers do you want in the array: ");
               int x1= in.nextInt();
               int array1[] = new int[x1];
               for (int i = 0; i < array1.length; i++)

           default:
               System.out.println("Invalid input");
          
       }
   }
}

The 2D array prints correctly

(I.e. 2 rows, 3 columns, input 1 2 3 4 5 6

outputs

123

456 )

but my 3D array prints everything in a straingt line down, it doesn't print rows. How do I fix this?

And in each case statement I also need to print out the average of all elements in the array.

Explanation / Answer

number is declared in the tomato() method not in the sauce() method
you want to use array but by mistake you typed number
also you wrote of your tomato() and sauce() methods in the main() method

you have to define methods in the class but outside other methods

this is how it should look
class project
{
main()
{
....
}
tomato()
{
...
}
sauce()
{
....
}
}


Let me fix this for you


import java.util.Scanner;
public class Grades {
static int[] array=new int[10];
public static void main(String[] args) {
tomato();
sauce();
}

public static void tomato(){

Scanner reader = new Scanner(System.in);
int count = 0;
int i = 0;
while (count < array.length){
System.out.println("Enter the array numbers");
int number = reader.nextInt();
array [count] = number;
count++;}}

public static void sauce(){
for (int i = 0; i < array.length; i++)
if (array[i] <0)
System.out.println("Your negative numbers are: " + array[i]);}

}


edit: there where some typing mistakes, so i rewrote my program.. try it again
you cannot use variables of one method in the other method
variables in a method of local scope
you have to use static data members to use it in more than one functions
alternatively, you can pass it as a parameter to your method
