java - Apache POI: How to set font style for a field (PAGE, PAGENUM, PAGEREF...) -


from (answered) question learned how add page counter word document. in addition need set font family style (color, bold, italic, underline...) on field (i.e. page counter). how can achieved?

ctsimplefield ctsimplefield = paragraph.getctp().addnewfldsimple();

ctsimplefield not provide methods directly set these attributes.

original question: how add page numbers in format x of y while creating word document using apache poi api?

import java.io.*;  import org.apache.poi.xwpf.usermodel.*;  import org.apache.poi.xwpf.model.xwpfheaderfooterpolicy;  public class createwordheaderfooter {   public static void main(string[] args) throws exception {    xwpfdocument doc= new xwpfdocument();    // body content   xwpfparagraph paragraph = doc.createparagraph();   xwpfrun run=paragraph.createrun();     run.settext("the body:");    paragraph = doc.createparagraph();   run=paragraph.createrun();     run.settext("lorem ipsum.... page 1");    paragraph = doc.createparagraph();   run=paragraph.createrun();   run.addbreak(breaktype.page);    run.settext("lorem ipsum.... page 2");    paragraph = doc.createparagraph();   run=paragraph.createrun();   run.addbreak(breaktype.page);    run.settext("lorem ipsum.... page 3");    // create header-footer   xwpfheaderfooterpolicy headerfooterpolicy = doc.getheaderfooterpolicy();   if (headerfooterpolicy == null) headerfooterpolicy = doc.createheaderfooterpolicy();    // create header start   xwpfheader header = headerfooterpolicy.createheader(xwpfheaderfooterpolicy.default);    paragraph = header.getparagrapharray(0);   if (paragraph == null) paragraph = header.createparagraph();   paragraph.setalignment(paragraphalignment.left);    run = paragraph.createrun();     run.settext("the header:");    // create footer start   xwpffooter footer = headerfooterpolicy.createfooter(xwpfheaderfooterpolicy.default);    paragraph = footer.getparagrapharray(0);   if (paragraph == null) paragraph = footer.createparagraph();   paragraph.setalignment(paragraphalignment.center);    run = paragraph.createrun();     run.settext("page ");   // adds page counter   paragraph.getctp().addnewfldsimple().setinstr("page \\* mergeformat");   run = paragraph.createrun();   run.settext(" of ");   // adds page total number   paragraph.getctp().addnewfldsimple().setinstr("numpages \\* mergeformat");    doc.write(new fileoutputstream("createwordheaderfooter.docx"));   } }

to able formatting, need runs in word. create fields using runs need 3 runs each field. 1 run mark fldchar start, 1 run mark fields instrtext , third run mark fldchar end. , each run can, must, formatted needed.

example:

import java.io.*;  import org.apache.poi.xwpf.usermodel.*;  import org.apache.poi.xwpf.model.xwpfheaderfooterpolicy;  public class createwordheaderfooter {   public static void main(string[] args) throws exception {    xwpfdocument doc= new xwpfdocument();    // body content   xwpfparagraph paragraph = doc.createparagraph();   xwpfrun run=paragraph.createrun();     run.settext("the body:");    paragraph = doc.createparagraph();   run=paragraph.createrun();     run.settext("lorem ipsum.... page 1");    paragraph = doc.createparagraph();   run=paragraph.createrun();   run.addbreak(breaktype.page);    run.settext("lorem ipsum.... page 2");    paragraph = doc.createparagraph();   run=paragraph.createrun();   run.addbreak(breaktype.page);    run.settext("lorem ipsum.... page 3");    // create header-footer   xwpfheaderfooterpolicy headerfooterpolicy = doc.getheaderfooterpolicy();   if (headerfooterpolicy == null) headerfooterpolicy = doc.createheaderfooterpolicy();    // create header start   xwpfheader header = headerfooterpolicy.createheader(xwpfheaderfooterpolicy.default);    paragraph = header.getparagrapharray(0);   if (paragraph == null) paragraph = header.createparagraph();   paragraph.setalignment(paragraphalignment.left);    run = paragraph.createrun();     run.settext("the header:");    // create footer start   xwpffooter footer = headerfooterpolicy.createfooter(xwpfheaderfooterpolicy.default);    paragraph = footer.getparagrapharray(0);   if (paragraph == null) paragraph = footer.createparagraph();   paragraph.setalignment(paragraphalignment.center);    run = paragraph.createrun();   run.setbold(true);     run.settext("page ");    run = paragraph.createrun();     run.setbold(true);    run.getctr().addnewfldchar().setfldchartype(org.openxmlformats.schemas.wordprocessingml.x2006.main.stfldchartype.begin);    run = paragraph.createrun();    run.setbold(true);    run.getctr().addnewinstrtext().setstringvalue("page \\* mergeformat");    run = paragraph.createrun();     run.setbold(true);    run.getctr().addnewfldchar().setfldchartype(org.openxmlformats.schemas.wordprocessingml.x2006.main.stfldchartype.end);    run = paragraph.createrun();     run.setbold(true);    run.settext(" of ");    run = paragraph.createrun();     run.setbold(true);    run.getctr().addnewfldchar().setfldchartype(org.openxmlformats.schemas.wordprocessingml.x2006.main.stfldchartype.begin);    run = paragraph.createrun();     run.setbold(true);    run.getctr().addnewinstrtext().setstringvalue("numpages \\* mergeformat");    run = paragraph.createrun();     run.setbold(true);    run.getctr().addnewfldchar().setfldchartype(org.openxmlformats.schemas.wordprocessingml.x2006.main.stfldchartype.end);    doc.write(new fileoutputstream("createwordheaderfooter.docx"));   } }

arrays - What causes a java.lang.ArrayIndexOutOfBoundsException and how do I prevent it? -

what arrayindexoutofboundsexception mean , how rid of it? here code sample triggers exception: string[] name = {"tom", "dick", "harry"}; for(int = 0; i<=name.length; i++) { system.out.print(name[i] +'\n'); } your first port of call should documentation explains reasonably clearly: thrown indicate array has been accessed illegal index. index either negative or greater or equal size of array. so example: int[] array = new int[5]; int boom = array[10]; // throws exception as how avoid it... um, don't that. careful array indexes. one problem people run thinking arrays 1-indexed, e.g. int[] array = new int[5]; // ... populate array here ... (int index = 1; index <= array.length; index++) { system.out.println(array[index]); } that miss out first element (index 0) , throw exception when index 5. valid indexes here 0-4 inclusive. correct, idiomatic for statement here be: for (int index = 0; index <...
