In this statement Object[][] data = new Object[sheet.getLastRowNum()][sheet.getRow(0).getLastCellNum()]; It is creating an array of references to arrays of references to Objects. The first array is for rows and the leaf arrays are for column values. In reality, only String objects are added so I would write it like this. int rows = sheet.getLastRowNum(); int columns … Read more

You can give it a callback function that will have the this scoped. $(‘div’).html(function(){ return $(this).data(‘test’); }); <script src=”https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js”></script> <div data-test=”test”></div> <div data-test=”secondary test”></div> Or, seriously, just use a variable (if there is only one). var $div = $(‘#element’); $div.html($div.data(‘test’)); <script src=”https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js”></script> <div id=”element” data-test=”test”></div> 3 solved this in chained jquery functions
