Both those bits of code suffer from all sorts of stylistic errors, e.g. too many blank lines, use of CapitalLetters in variable names and poorly‑named variables (F).
What you had in the first piece of code is two methods which are override‑equivalent, i.e. they have the same signature
search(int[], int)
If you call those methods from elsewhere, the javac tool will not be able to distinguish which of the two you actually want, so the code will fail to compile.

This is how you ought to have formatted the code.I shall leave you to work out why a utility class has a private constructor.

You are getting confused about names of parameters and their meanings. You might do well to change the heading of the method to something like this:-Now you can see that you are looking for any value in the arra and you are calling it i. You would not usually use 1‑letter parameter names, but here you do not know what the number means, only that it is a number. So you can searchIf you are searching for a different type, you would probably write a generic method, calling the equals() method (not the == operator).
 
It is sorta covered in the JavaRanch Style Guide.
