I want to read excel sheet values and store those values in an array in Java.
I have code ready to read excel sheet but i am not able to customize it to store those values in Array.
Here is my code to read an excel sheet :
package com.core.testscripts; import java.io.File; import java.io.IOException; import jxl.Cell; import jxl.Sheet; import jxl.Workbook; import jxl.read.biff.BiffException; public class NewExcel { private String inputFile; public void setInputFile(String inputFile) { this.inputFile = inputFile; } public void read() throws IOException { File inputWorkbook = new File(inputFile); Workbook w; try { w = Workbook.getWorkbook(inputWorkbook); // Get the first sheet Sheet sheet = w.getSheet(0); // Loop over first 10 column and lines for (int j = 0; j < sheet.getColumns(); j++) { for (int i = 0; i < sheet.getRows(); i++) { Cell cell = sheet.getCell(j, i); System.out.println(cell.getContents()); } } } catch (BiffException e) { e.printStackTrace(); } } public static void main(String[] args) throws IOException { NewExcel test = new NewExcel(); test.setInputFile("D:/hellohowareyou.xls"); test.read(); } }
