“cannot resolve symbol” means that the Java compiler cannot locate a symbol referenced in your Java source code.
The causes for this common error include:
- A missing class file
- A faulty CLASSPATH
- A symbol name is mispelled or miscapitalized
- A data type is incorrect, misspelled, or miscapitalized
- A method is called with the wrong number or types of arguments
- An undeclared variable
cannot resolve symbol errors can be very difficult to track down. Code carefully!
