New Features and Enhancements from JDK-5 to JDK-7

As Oracle is preparing for JDK-8 release with most awaited language features " lambda expressions", I was thinking about the java language evolution since I started my IT career.

New features released in JDK-5 were really impressive, and it created lots of interest in language again.

JDK-5 (September 30, 2004)

JDK-6 (December 11, 2006)

JDK-7 (July 28, 2011)

Over the past few years, java has become more relevant. It has quietly become the primary foundation for really big companies like Google, LinkedIn, Tumbler, Square and Twitter.

“Java is really the only choice when it comes to the requirements for a company like ours — extreme performance requirements and extreme scalability requirements. There is no viable alternative”— Bob Lee

“On August 3, Twitter hit a one-second peak of 143,199 tweets. That’s a massive spike over the norm — about 5,700-tweets-per-second — and the site stayed up”— New Tweets per second record, and how!

ERROR: Ignored call to 'alert()'. The document is sandboxed, and the 'allow-modals' keyword is not set.

Recently I found this issue while writing code snippet in "JSFiddle". And after searching, found this was happening because of new feature added in "Chrome 46+". But at the same time Chrome doesn't have support for "allow-modals" property in "sandbox" attribute.

Chromium issue for above behavior:
https://codereview.chromium.org/1126253007

To make it work you have to add "allow-scripts allow-modals" in "sandbox" attribute, and use "window.alert" instead of "alert".



<!-- Sandbox frame will execute javascript and show modal dialogs --> <iframe sandbox="allow-scripts allow-modals" src="iframe.html"> </iframe>


Feature added: Block modal dialog inside a sandboxed iframe.

JavaScript [ExtJs3]: EditorGridPanel Read-Only (dynamically)

Many time we face the scenerio where we have to make the editor grid read-only dynamically.


Ext.override(Ext.ux.grid.CheckColumn, { editable: true, onMouseDown: function (e, t) { if (Ext.fly(t).hasClass(this.createId())) { e.stopEvent(); var me = this, grid = me.grid, view = grid.getView(), index = view.findRowIndex(t), colindex = view.findCellIndex(t), record = grid.store.getAt(index); if (!grid.isReadOnly && grid.colModel.isCellEditable(colindex, index)) { record.set(me.dataIndex, !record.data[me.dataIndex]); } } } }); var grid = new Ext.grid.EditorGridPanel({ ... isReadOnly: true, //set to flag to make check column readonly ... }); //to make other column readonly grid.on('beforeedit', function () { return false; });

JavaScript [ExtJs3]: Total “Record” count in filtered store

There is two way to get record count from the Store
store.getTotalCount() This function depend on server response value. For accuracy of the value, property shell if return by the server.

Property name for the diff. reader:
totalProperty for JsonReader, totalRecords for XmlReaderstore.getCount() Will return you the number of record from the store.
Or if you have filter on the store, it will give you the number of filtered record.
But if you want to get the total number of record regardless filtering, Then it will be like this

var totalRecords = store.snapshot ? store.snapshot.length : store.getCount();
“snapshot” is the variable in “Store” which hold the actual data in case if you have applied a filter.
