Java-Syntax error on token(s), misplaced construct(s)
im tun, eine java-Automaten os und ich gerade importiert haben, meine ursprüngliche Projekt in eclipse, und fügte hinzu, ein Kerl Seite und da dann schon werfen Fehler überall, egal was ich mache, bekomme ich Hilfe? die wichtigsten Fehler, jetzt ist 'Syntax error on token(s), misplaced construct(s)' ich entschuldige mich im Voraus, wenn der code schlecht oder ineffizient Fetzen rumfliegen.
