Help with Two Dimensional Array

[johnjacob]

Okay so I have a two dimensional array and I am trying to find out how many even numbers have been generated, and I need to display the count. Below I started trying to create a method for findEven but ran into some problems with it when I tried to compile. Im not sure if I wrote the method correctly. Any help would greatly be appreciated.

import java.util.*;
       import java.math.*;

       public class twodim {


              public static void (findEven)
                for (x = 2;  x<= 20; x = x + 2) {
                                  System.out.println( x );
                               }

                                for (y = 2;  y<= 20; y = y + 2) {
                                                  System.out.println( y );
                               }



   public static void main(String[] args) {

               final int row = 4;
               final int col = 4;

               Random rand = new Random();

               int [][] twoDarray = new int [row][col];


               for (int x = 0; x < twoDarray.length; x++) {

                   for (int y = 0; y < twoDarray[x].length; y++) {

                       twoDarray[x][y] = rand.nextInt(1000);
                   }
               }


               for(int i = 0; i < twoDarray.length; i++) {

                   for(int j = 0; j < twoDarray[i].length; j++) {

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

                   }
                   System.out.println();
               }

           }
           }

Oohhhh ...
public static void (findEven)
for (x = 2; x<= 20; x = x + 2) {

this is not a java syntax :)

Look here:

import java.util.Random;

public class twodim {

	public static void findEven() {
		for (int x = 2; x <= 20; x = x + 2) {
			System.out.println(x);
		}

		for (int y = 2; y <= 20; y = y + 2) {
			System.out.println(y);
		}
	}

	public static void main(String[] args) {

		final int row = 4;
		final int col = 4;

		Random rand = new Random();

		int[][] twoDarray = new int[row][col];

		for (int x = 0; x < twoDarray.length; x++) {

			for (int y = 0; y < twoDarray[x].length; y++) {

				twoDarray[x][y] = rand.nextInt(1000);
			}
		}

		for (int i = 0; i < twoDarray.length; i++) {

			for (int j = 0; j < twoDarray[i].length; j++) {

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

			}
			System.out.println();
		}

	}
}

Below I started trying to create a method for findEven but ran into some problems with it when I tried to compile.

Which tells us absolutely NOTHING.

And your code is in very bad shape. Where is the method name? Inside brackets? No opening/closing braces for method. Where have you declared the x and y variables that you are using inside your for loop?

Read some basic stuff first : Trail: Learning the Java Language
