推荐答案

终于成功了！！！ 在setValue语句中进行的更改，并替换为((PDCheckbox)feld3).check();

Finally got it work !!!! change made in setValue statment and replaced with ((PDCheckbox) feld3).check();

public void check() throws Exception 
    {
        PDDocument fdeb = null;

        fdeb = PDDocument.load( "C:\\Users\\34\\Desktop\\complaintform.pdf" );

         PDAcroForm form = fdeb.getDocumentCatalog().getAcroForm();
         PDField feld3 = form.getField("loan");
         ((PDCheckbox) feld3).check();


         fdeb.save("C:\\Users\\34\\Desktop\\complaintform.pdf");
         fdeb.close();

    }
