Location: Variable Out Of Type Printstream


Here is an example of how incorrect variable scoping can lead to a "Cannot find symbol" error: for (int i = 0; i < strings.size(); i++) { if (strings.get(i).equalsIgnoreCase("fnoord")) { break; It means that either there is a problem in your Java source code, or there is a problem in the way that you are compiling it. posted 2 years ago I wrote a VERY simple program to print out the words of "99 Bottles of Beer on the Wall" and I cannot compile it because of 6 The next line of the error message (which says "found") tells you what you (incorrectly) tried to use to call the method.

For example: public class Test { public static void main(String[] args) { String str = "Hello, world!"; String a = str.substring(-1, 3); String b = str.charAt(str.length()); String c = str.substring(0, 20); using an IDE, Ant, Maven, Gradle and so on. If you have never compiled Bar and you run javac Foo.java, you are liable to find that the compiler can't find the symbol Bar. The time now is 08:01 PM.

incompatible types This error occurs when there are type issues with your program. Variable Might Not Have Been Initialized Consider this code: if(somethingIsTrue()) { String message = "Everything is fine"; } else { String message = "We have an error"; } System.out.println(message); That's invalid code. For example, if you have classes Foo and Bar where Foo uses Bar. This is not a compile-time error, but rather a runtime error.

Homoglyphs: If you use UTF-8 encoding for your source files, it is possible to have identifiers that look the same, but are in fact different because they contain homoglyphs.
