RE: Incompatible types error from getIndexHash()

Nice to know. I've just begun working with Java 6 after working with 1.4 for years and years. New compiler tricks to learn!

Hi, Dan and Peter --

You don't need to import java.lang.Integer. Each compilation unit acts as if an

import java.lang.*;

statement is included at the beginning of the compilation unit immediately after any package statement. (JLS 7.5.5).

All recent compilers (starting with Java 5) support autoboxing. The int will automatically be converted to an Integer. See JLS 15.12.2.3, 5.3, and 5.1.7.

The problem here is that only beta POI versions of getIndexHash return a typed Map<Integer, HSSFColor>. Production POI releases return a Hashtable.
Therefore, the return value from the getIndexHash().get(xxx) method needs the (HSSFColor) cast unless Peter is working with a beta version.

HTH,
Gary

The java object of type Integer is different than the primitive int.
HSSFFont.getColor() actually returns a short, but java will
automatically cast short to int. The Map object returned by
HSSFColor.getIndexHash() is indexed by Integer. Should go something
like below. If you're using a recent build of POI that supports
generic types, the value of the hash is already declared as HSSFColor,
so it doesn't need to be cast.

HSSFColor color =
HSSFColor.getIndexHash().get(Integer.valueOf(colorIndex));

You will wind up also with

import java.lang.Integer

IANAJP (I am not a Java programmer), so please don't expect much, i.e.
it may be a totally obvious error.

I get the following error when compiling a java program I'm trying to
use to figure out how to get the color of text in a cell.

testjava.java:33: incompatible types
found : java.lang.Object
required: org.apache.poi.hssf.util.HSSFColor
HSSFColor color = HSSFColor.getIndexHash().get(colorIndex);
^
1 error

Here's the entire program:

import java.io.*;
import java.util.Map;

import org.apache.poi.hssf.usermodel.HSSFCell;
import org.apache.poi.hssf.usermodel.HSSFCellStyle;
import org.apache.poi.hssf.usermodel.HSSFFont;
import org.apache.poi.hssf.usermodel.HSSFRow;
import org.apache.poi.hssf.usermodel.HSSFSheet;
import org.apache.poi.hssf.usermodel.HSSFWorkbook;
import org.apache.poi.hssf.usermodel.HSSFRichTextString;
import org.apache.poi.hssf.util.HSSFColor;
import org.apache.poi.poifs.filesystem.POIFSFileSystem;

public class testjava {

public static void main () {

FileInputStream in = new FileInputStream("/home/pdow/test.xls");
POIFSFileSystem fs = new POIFSFileSystem(in);
HSSFWorkbook wb = new HSSFWorkbook(fs);

// The following code is from this thread:
//
http://apache-poi.1045710.n5.nabble.com/hssf-and-multiple-colors-per-
cell-td3425176.html


HSSFRichTextString str =
wb.getSheetAt(1).getRow(3).getCell(0).getRichStringCellValue();
for(int i = 0; i < str.numFormattingRuns(); i++){
short fontIndex = str.getFontOfFormattingRun(i);
HSSFFont font = wb.getFontAt(fontIndex);
int colorIndex = font.getColor();
HSSFColor color = HSSFColor.getIndexHash().get(colorIndex);
System.out.println(color);
}
}

I'm hoping it's something totally obvious to someone!
