You must import either a packagename.* or packagename. In your own classes, try to use globally unique class names. Perhaps you declared it inside a block/loop and you tried to use it outside the block/loop.

This code sample reproduces exactly your compilation error: class StringAndObject { public void workWithString( String s ) {} // We just care about public void workWithObject( Object o ) {} //

Whereas Lists (e.g. no field No field named length was found in type java/lang/String You said s.length rather than s.length() to get the length of a String. The enum constant is said to be created when the corresponding field is initialized. ~ Java Language Spec In other words, the gotchas is a side effect of the kludgy way main must be public static void.

You want to store ints, so the Integer wrapper class would fit best: public static void insert(List l, int data) { for (int i = 0; i < l.size(); i++) { Usually this is just a missing semicolon, sometimes it can be caused by unbalanced () on the previous line. You may have used a reference to an inner class inside a static method. this contact form at the command line you typed: javac.exe MyClass instead of: javac.exe MyClass.java This is one of the most maliciously misleading of all error messages.

I highly recommend to use Generics while using any Collection classes or class which acts as container e.g. class names unchecked only accepted for annotation processing error: Class names, "unchecked", are only accepted if annotation processing is explicitly requested For Netbeans, uncheck the project’s property entitled Enable Annotation Processing case fallthru no warning. class and interface must be all lower case.

Not the answer you're looking for? Most commonly you have left off the parameters on a method.
