在方法之间传递值

Question

I've got method where I read value into variable

public void displayFromExcel(String xlsPath) {
. 
. 
. 
pole[i] = cell.getNumericCellValue();
.
.
pole1[j] = richTextString;

Then I have method where I build a String using StringBuilder

    private void getHenkValues (StringBuilder sb) { 
    sb.append("<ColumnValue name=\"hen_allockey\">" + pole1[j] + "</ColumnValue\">\r\n"
            +"<ColumnValue name=\"hen_percentage\">"+ pole[i] + "</ColumnValue\">\r\n");
}

Then I have method where I write it into file:

protected void jobRun() throws Exception {
sb = new StringBuilder();
getHenkValues(sb);
String epilog1 = sb.toString();

FileOutputStream fos = new FileOutputStream("c:\\test\\osem.xml");
OutputStreamWriter osw = new OutputStreamWriter(fos, Charset.forName("UTF-8"));
osw.write(epilog1);
osw.flush();
osw.close();  
}

And in method main I call the method jobrun .

How can I get the values from pole[i] , pole1[j] from method displayFromExcel to method getHenkValues ?

Answer 1

Your displayFromExcel method need to return them (using a custom class or a collection of some sort, perhaps an array).

Your getHenkValues needs to accept these values as well, you could try something like:

getHenkValues(StringBuilder sb, Object value1, Object value2)

or whatever is relevant for your case.

Answer 2

You could make pole and pole1 private fields of the class in which displayFromExcel, getHenkValues and jobRun are located:

private Object[] pole;
private String[] pole1;

Then you can assign values to these arrays in one method and access them in another.
