    data.put("2", new Object[]{1, "Amit", "Shukla"});

    int rownum = 0;
    for (String key : keyset) 
    {
        //create a row of excelsheet
        Row row = sheet.createRow(rownum++);

        //get object array of prerticuler key
        Object[] objArr = data.get(key);

        int cellnum = 0;

        for (Object obj : objArr) 
        {
            Cell cell = row.createCell(cellnum++);
            if (obj instanceof String) 
            {
                cell.setCellValue((String) obj);
            }
            else if (obj instanceof Integer) 
            {

        //Write the workbook in file system
        FileOutputStream out = new FileOutputStream(new File("C:\\Documents and Settings\\admin\\Desktop\\imp data\\howtodoinjava_demo.xlsx"));
        workbook.write(out);
        out.close();
        System.out.println("howtodoinjava_demo.xlsx written successfully on disk.");
    } 
    catch (Exception e)
    {
        e.printStackTrace();
    }

    }

You need to place all statements after the declarations in a code block, e.g. method rather than the class block. Logically it probably makes sense to place all statements in the code block but the non-declarative statements need to be enclosed within the new block

private void processFile() {
    data.put("1", new Object[]{"ID","NAME", "LASTNAME"}); // <--Syntax error  
     ...//snip
  } catch (Exception e) {
     e.printStackTrace();
  } 
}
