If 'Example.java' is a standalone Java file that is not part of any project structure, and it contains only syntax errors, you can expect to see compiler-generated error messages. These messages will typically indicate issues with the code's compliance with the Java language specification. Here are some common error messages you might encounter:
1. **SyntaxError**: This is the most basic error indicating a problem with the syntax, such as missing semicolons, unmatched brackets, or incorrect use of keywords.
```
Example.java:1: error: ';' expected
// Incorrect line here
^
```
2. **MissingTypeDeclaration**: If a class, interface, or variable declaration is incomplete, you'll get an error for this.
```
Example.java:5: error: class, interface, or enum expected
method(); // Missing 'class' keyword or '{'
^
```
3. **InvalidVariableName**: Names used in identifiers must follow certain rules (e.g., cannot start with numbers).
```
Example.java:7: error: illegal name
int$3 = 0; // Invalid because '$' is not allowed as a first character
^
```
4. **UnresolvedReferences**: If you reference a class or method that hasn't been imported or defined, you'll get an error like this.
```
Example.java:10: error: cannot find symbol
MyClass myObject; // Error since MyClass is not declared
^
```
5. **RedefinedIdentifier**: If a variable, class, or import is accidentally redefined within the same scope, you'll receive an error.
```
Example.java:15: error: already assigned to
int x = 5; // First assignment
x = 10; // Second assignment, generates error
```
To resolve these errors, carefully review the highlighted lines in the compiler output and fix the syntax issues according to the Java Language Specification. Make sure to adhere to proper indentation, curly braces, and correct usage of language constructs.
