How to display elements of an array?

Question

I'm still learning Java and I was wondering how can I access an element of an array? For example, I have this array:

private int[] employeeNum={5658845, 4520125, 7895122, 8777541, 1302850, 7580489};

And I want to display the number "450125" while using a for loop. What should I do? Also, if you have a better method rather than a for loop, please feel free to put it; it would be much appreciated. I'll put in the for loop I'm using just in case :

for(int i=0; i<6; i++) {
    System.out.println("Enter the hours worked by employee number " +
    employeeNum[i] + ":");
}

import java.util.Arrays; System.out.println( Arrays.toString(employeeNum) ); — Hunter McMillen

Do you want to display 45202125 or do you want to display the second element in your array? these are two very different questions. — DwB

By "access an element of an array", do you mean "find a specific value in an array"? — Sizik

Your accessing array elements in your for loop. employeeNum[i] is getting the element at index i. — mbiokyle

If you would like to display the second element in an array, you simply need to do this: arrayName[indexNumber]
In your case, you would need to use this syntax:
employeeNum[1]

An index (such as "indexNumber" and "1" used above) is simply an address. The former being a variable representing a number, and the latter being a number. Imagine you had ten houses on the right side of a given street. If you were to explain to someone else how to get to the second house on the right, you would say something like this:
houses[1]
Why did I put a '1' instead of a '2'?
Because, in programming, you start counting at '0' instead of '1'.
I hope this helps. Be sure to up-vote those comments that are helpful, and mark the best answer.
