I need help with a Object Array

Question

I am having trouble and this maybe really simple seeing that I am fairly new to java but I have text that is being broken down in to preset part with those parts stored in Object arrays.
Now I also have a object array inside my object array. Within the second object array are the broken down parts of the text and I want to compare this text with another string so for example this is what I am trying
boolean found = false;
for (int i = 0; i < FirstObjectArray.length ;i++)
     Object[] SecondObjectArray = (Object[]) FirstObjectArray;
     if(SecondObjectArray[0] == "string")
          found = true;
          break;
     else
          found = false;
}Help would be very appreciated.

Sure, you're right.

sharkura said all the OP needs at the moment. I just wanted to clarify a bit why You don't use == 99.999% of the time with objects, and never with String.
I have argued elsewhere in these forums that it is inappropriate to tell anyone that you never use == to compare objects. This has not always been accepted. I have, on rare occasions, known experienced developers to blindly compare two objects with equals(), and cite the professor that taught them, 15 years iin the past, that object references are never compared using ==, but always with equals().
However, the cases where == is appropriate and equals() is not are indeed rare, but not, in my experience, non-existent. In my statement, I probably exaggerated. And String is a case where I can probably accept that you will probably never go wrong with equals(). If the String has been pooled (see String::intern()), you can actually use either. From the javadocs: "*It follows that for any two strings s and t, s.intern() == t.intern() is true if and only if s.equals(t) is true.*"
