Consider:
public proj 3 { static string [][]Item; public static void main(String [] args){ Item[][] = { {\"BH,\" , \"Backhoe,
You have two options: In the declaration
private static String[][] item = {...};
OR
Elsewhere using the new keyword private static String[][] item = new String[][]{...}
new
private static String[][] item = new String[][]{...}
Also, you'll need to change public proj to public class
public proj
public class
