Topic: Whence an error cannot access java.lang. StringBuilder;
I will not understand, for some reason in line
else {
throw new RuntimeException ("For some reason at the character" + symb.toString () + "it turned out more than three types");
}
There is an error
"MetQueryLexicAnalyser.java": cannot access java.lang. StringBuilder; java.lang. StringBuilder at line 61, column 75
What could it mean?
