String is not equal to string?

I’m new to java and I can’t figure out what’s wrong with this code block.
I know the array isn’t null I’m testing it elsewhere. Maybe there is a syntax problem I’m used to program in c#.

     Scanner input = new Scanner(System.in);
     System.out.println("Enter ID :");
     String employeeId = input.nextLine();
     int index =  -1;
     for(int i = 0 ; i < employeeCounter ; i++)
     {
         if(employeeId == employeeNumber[i])
         {
           index = i;
         }
     }

     if(index == -1)
     {
         System.out.println("Invalid");
         return;
     }

I always get to the ‘Invalid’ part. Any idea why ?
Thanks in advance

employeeNumber[0] is "12345"
employeeId is "12345"
but I can,t get into the first if statement although employeeId IS equal to employeeNumber[0].

Don’t compare strings with ==.

Use

if (string1.equals("other")) {
    // they match
}
