Question

Im setting up a simple method and I keep getting the following error:

Syntax error on token “double”, @ expected

Here is my method:

public double Calculate ()  {

 }

The method is just a simple calculation. I have even tried a very simple method like this:

 public void Calculate ()  {

 }

Syntax error on token “void”, @ expected

Eclipse is still giving me the error. What am I missing here?

Thanks!

Answer 1

This error occurs in Java class file without class declaration.

If you want Java class (and probably you want some) you need to do something like this:

public class TestClass {
    public double calculate() {
        return 0;
    }
}

If you miss class declaration both your error occurs:

public double calculate() {
}

There are 2 errors showing:

• Syntax error on token “double”, @ expected
• Syntax error, insert “enum Identifier” to complete EnumHeader

There are also The Code Conventions for the Java Programming Language you should learn with language too f.e. method names start with lowercase letter.
