Storing data in Array or StringBuffer and then comparing it to a string

Question

I want to store some data in a list or an Array (but apparently an Array only holds 10 items?) and then I want to be able to check if myString is equal to any of the posts in the array/list.
Or if I use a StringBuffer I want to check to see if myString is part of the StringBuffer?
How do I do this?

Answer 1

I want to store some data in a list or an Array (but
apparently an Array only holds 10 items?)Uh, no. Arrays can (theoretically) contain Integer.MAX_VALUE elements.
and then I want to be able to check if myString is equal to any
of the posts in the array/list.Don't confuse String's equals() method with the equality operator '=='. The == operator checks that two references refer to the same object. If you want to compare the contents of Strings (whether two strings contain the same character sequence), use equals(), e.g. if (str1.equals(str2))...
Example:String s1 = "foo";
String s2 = new String("foo");
System.out.println("s1 == s2: " + (s1 == s2)); // false
System.out.println("s1.equals(s2): " + (s1.equals(s2))); // trueFor more information, check out Comparison operators: equals() versus ==
Or if I use a StringBuffer I want to check to see if
myString is part of the StringBuffer?See above discussion on .equals().
How do I do this?
