使用pdfbox创建pdf时出错：此令牌后预期的标识符

Question

I am working on a plain Java project in eclipse juno using jre6/jdk6 as runtime/compiler. I wish to use apache pdfbox to generate some pdfs. i have downloaded and added pdfbox 1.8.9 to my build path. now i took a code sample from here , and used it in my application, but it is giving me multiple error which i think is related to some environment problems.

import org.apache.pdfbox.pdmodel.PDDocument;
import org.apache.pdfbox.pdmodel.PDPage;
public class TestPdf {

PDDocument document = new PDDocument();
// Create a new blank page and add it to the document
PDPage blankPage = new PDPage();
document.addPage( blankPage );
// Save the newly created document
document.save("BlankPage.pdf");
// finally make sure that the document is properly
// closed.
document.close();
}

These are the errors i am getting :

Syntax error on token "blankPage", VariableDeclaratorId expected after this token
Syntax error on token ""BlankPage.pdf"", delete this token
Syntax error on token "close", Identifier expected after this token

You should create a method and move some of the code inside the method :

public class TestPdf {

    PDDocument document = new PDDocument();
    // Create a new blank page and add it to the document
    PDPage blankPage = new PDPage();

    public void createDocument()throws Exception {
        document.addPage(blankPage);
        // Save the newly created document
        document.save("BlankPage.pdf");
        // finally make sure that the document is properly
        // closed.
        document.close();
    }
}

The code that you posted in your question is against the syntax rules of the Java language. You can read more about the structure of a class here
