Hi, Adding methods for comparing CharSequence, StringBuilder, and StringBuffer. The Comparable implementations for StringBuilder/Buffer are similar to that of String, allowing comparison operations between two StringBuilders/Buffers, e.g. aStringBuilder.compareTo(anotherStringBuilder). For CharSequence however, refer to the comments in JIRA, a static method 'compare' is added instead of implementing the Comparable interface. This 'compare' method may take CharSequence implementations such as String, StringBuilder and StringBuffer, making it possible to perform comparison among them. The previous example for example is equivalent to CharSequence.compare(aStringBuilder, anotherStringBuilder). Tests for java.base have been independent from each other. The new tests are therefore created to have no dependency on each other or sharing any code.
