This article provides a comprehensive analysis of the "java.lang.CharSequence cannot be resolved" error commonly encountered in Eclipse development environments. The issue typically stems from a mismatch between Java 8's interface default methods and project source level settings. Through examination of a specific case study from Q&A data, the paper details changes to the CharSequence interface in JDK 8, including new default methods like chars() and codePoints(). When project source level is below 1.8, compilers cannot properly handle these default methods, causing compilation failures in indirectly dependent classes.
