The javacc compiler should also have emitted a following line with a "^" that indicates exactly which part of that statement is invalid. (Remember to include the full compiler error in the post.) Make sure image is what the class is really called (the class should likely be called Image per the Java naming conventions) and that any required imports are used if the "image" class is in a different namespace. It could also simply be that the compiler can't find the corresponding "image" class if it is not looking at the correct location for the the JAR/".class"/".java" files. Providing more context (e.g. the definition of the "image" class and the namesp

I get a syntax error in Eclipse.

You can't call a class, you have to call a method that is declared inside a class. WRONG: class ClassName { for (...) } CORRECT: class ClassName { static void method() { for (...) } public static void main(String[] args) { ClassName.method(); } } share|improve this answer answered Oct 9 '12 at 16:42 Jack 90.4k21141250 add a comment| up vote 2 down vote You can not define method a

The point of my program is to shift my input file by whatever the user inputs. My errors that I commented out are kind of pointless to me because it all make sense and the computer is not reading it the way I want it to. Not to be confused with one of the errors that I commented one syntax error on of the tokens is ",". The others are "(", and ")". These all are errors that expect a semi colon somewhere in the line where I commented them. Here is what the program looks like: import java.util.*; import java.io.*; class CaesarCipher { public static void main (String [] args) throws FileNotFoundException { Scanner keyboard = new Scanner(System.in); System.out.println("What shift should I use? "); int shift = keyboard.nextInt(); System.out.println("What is the name of the input file? "); String name = keyboard.next(); File f = new File(name); Scanner inFile = new Scanner(f); System.out.println("What is the name of the output file? "); String text = keyboard.nextLine(); PrintWriter outFile = new PrintWriter(text); String encrypted = ""; while (inFile.hasNextLine()) { String line = inFile.nextLine(); if ( shift == 1) encrypted = caesarEncipher(line, shift); else if (shift == 2) encrypted = caesarDecipher(line, shift);// the method caesarDecipher(java.lang.String, int) is undefined for the type CaesarCipher System.out.println(encrypted); outFile.println(encrypted); } } static String caesarEncipher(String text ,int shift) throws FileNotFoundException { String t = ""; int i = 0; while (i < t.length()) { if (shift < 0) { shift = (shift % 26) + 26; } int move = (char) ((text.charAt(0) - 'A' + shift) % 26 + 'A'); t += move; i++
to this and will issue an error message which depends on which keyword was capitalised. The compiler will issue an error message such as: Line nn: class or interface declaration expected when, for example, you capitalise the keyword class. Writing a string over a new line Sometimes you will need to write a long string. A common error is to have a new line embedded in the string. The compiler will object to this and will issue an error message such as: Line nn: ';' expected When this happens the solution is to split the string into two, making sure that neither string has a new line in it, and concatenate them with +. Thus you might replace: String s = "A very long string which just happens to go over the end of a line and causes a problem with the compiler"; with: String s = "A very long string which just happens to go over the end "+ "of a line and causes a problem with the compiler" Missing brackets in a no-argument message When you use a method which has no arguments you should place brackets after the name of the method. For example, if you have declared a method carryOut with no arguments and you want to send a message corresponding to the method to the object objSend then you should code this as: objSend.carryOut() rather than: objSend.carryOut The compiler will usually emit an error message of the form: Line nn: Invalid expression statement Forgetting to import a package This one of the most common errors that inexperienced Java programmers make. If you forget to put the required import statement at the beginning of a program, then the compiler will respond with a message such as: Line nn: Class xxxx not found in type declaration Don't forget, though, that java.lang is imported automatically and, hence, does not need an import statement. Treating a static method as if it were an instance method Static methods are associated with messages sent to classes rather than objects. A common error is to send static method messages to objects. For example, in order to calculate the absolute value of an int value and place it into the int variable you should write: int result = Math.abs(value); rather than: int result = value.abs(); This gives rise to a variety of syntax errors.
