Java Is Platform Independent

Platform independent is a program capability of moving from one computer system to another.
Java is portable.
Java is security.
Java is simple.

We will discuss about  simple java program

Class firstjava {
public  static void main( String args [])
{
System. out.println("hello  world");
}
}

this program has two main parts:

All the program enclosed in a class definition:  - here class called first java.

Body  of the program contained in a method called main(). In java applications as in c and c++
Program. main() is the first method or function in the program that is run when  the program is executed.

Angularjs Image Crop

Whenever we allowing a user upload image, it's better to provide cropping option for them.  Touch support, swipe to move and drag handle to zoom image. Output as a base64 encoded data Url
Uses HTML5 Canvas to display image in a flexible context, to allow dragging and zooming.

.cropImage {
  background: #E4E4E4;
  overflow: hidden;
  width:500px;
  height:350px;
}


View.html

<body ng-app="app" ng-controller="Ctrl">
  <div>Select an image file: <input type="file" id="fileInput" /></div>
  <div class="cropImage">
    <img-crop image="myImage" result-image="myCroppedImage"></img-crop>
  </div>
  <div>Cropped Image:</div>
  <div><img ng-src="{{myCroppedImage}}" /></div>
</body>


Controller.js

angular.module('app', ['ngImgCrop'])
  .controller('Ctrl', function($scope) {
    $scope.myImage='';
    $scope.myCroppedImage='';

    var handleFileSelect=function(evt) {
      var file=evt.currentTarget.files[0];
      var reader = new FileReader();
      reader.onload = function (evt) {
        $scope.$apply(function($scope){
          $scope.myImage=evt.target.result;
        });
      };
      reader.readAsDataURL(file);
    };
    angular.element(document.querySelector('#fileInput')).on('change',handleFileSelect);
  });



Jquery() Function


jQuery to replace one tag with another

Using jQuery, I'm trying to replace all the occurrences of:
<p>.....</p>

With

<h1>.....</h1>

Code


$('p').replaceWith(function(){
    return $("<h1/>", {html: $(this).html()});
});



Disabling Right Mouse Click

If you are to disable right click on your web browser, you can use the following piece of code:

$(document).ready(function(){
$(document).bind("contextmenu",function(e){
return false;
});
});


Detect Current Mouse Coordinates

Now, suppose you need to detect the current mouse coordinates in the web browser in use. To do this, you can write the following piece of code:


$(document).ready(function() {
$().mousemove(function(e)
{
$('# MouseCoordinates ').html("X Axis Position = " + e.pageX + " and Y Axis Position = " + e.pageY);
});
<div id=MouseCoordinates></div>
});



Set a Timer

The following piece of code can be used to set a timer using jQuery:

$(document).ready(function()
{
window.setTimeout(function()
{
// some code
}, 1000);
});

Jquery Ajax()

Jquery Ajax Perform Async., HTTP Ajax Request.


jQuery.ajax(url,[settings])
Jquery Ajax
Jquery Ajax()

Url

A string containing the URL to which the request is sent.

Jquery Ajax simple Code:


context

$.ajax({
  url: "test.html",
  context: document.body
}).done(function() {
  $( this ).addClass( "done" );
});

another example:

var jqxhr =
    $.ajax({
        url: "/test.html",
        data: {
            name : "The name",
            desc : "The description"
        }
    })
    .done  (function(data, textStatus, jqXHR)        { alert("Success: " + response) ; })
    .fail  (function(jqXHR, textStatus, errorThrown) { alert("Error")   ; })
    .always(function(jqXHROrData, textStatus, jqXHROrErrorThrown)     { alert("complete"); })
    ;

JavaScript Tricks

javascripttricks

Java script programming is client side scripting language.  If you  are doing lot of java script programming. very useful  java script function and tricks.

1.Use the map() function method to loop through an array value

var squares = [1,2,3,4].map(function (val) {
    return val * val;
});
// squares will be equal to [1, 4, 9, 16]

2.Converting JavaScript Array to Comma Separated Value (CSV)

You have a java script array of string or number value and you want to convert it to comma separated values(csv).

Example Code:

var arrayval = ['cat', 'apple', 'oranges', 'chares'];

var string = arrayval .valueOf();

//print string: cat,apple,oranges,chares

The valueOf() method will convert an array in javascript to a comma separated string.


3.Rounding number to N decimal place

var num =5.72121756

num = num.toFixed(4);  // num will be equal to 5.7212

4.Remove Array element by Index

function removeByIndex(arr, index) {
    arr.splice(index, 1);
}

test = new Array();
test[0] = 'Cat';
test[1] = 'Ball';
test[2] = 'bird';
test[3] = 'penguen';

alert("Array before removing elements: "+test);

removeByIndex(test, 2);


alert("Array after removing elements: "+test);

5.Comma operator

var a = 0;
var b = ( a++, 99 );
console.log(a);  // a will be equal to 1

console.log(b);  // b is equal to 99


6. Generate Random number from 1 to N

//random number from 1 to N
var random = Math.floor(Math.random() * N + 1);

//random number from 1 to 10
var random = Math.floor(Math.random() * 10 + 1);

//random number from 1 to 100

var random = Math.floor(Math.random() * 100 + 1);

7.Listbox Select All/Deselect All using JavaScript

function listboxSelectDeselect(listID, isSelect) {
    var listboxs = document.getElementById(listID);
    for(var count=0; count < listboxs.options.length; count++) {
            listboxs.options[count].selected = isSelect;
    }

}


8.Remove Duplicates from JavaScript Array

function removeDuplicates(arr) {
    var temp = {};
    for (var i = 0; i &lt; arr.length; i++)
        temp[arr[i]] = true;
    var r = [];
    for (var k in temp)
        r.push(k);
    return r;
}
//Usage
var fruits = ['apple', 'orange', 'peach', 'apple', 'orange'];
var uniquefruits = removeDuplicates(fruits);
//print uniquefruits ['apple', 'orange', 'peach''];

9. Encode a URL in JavaScript

var encodeurl= 
       "http://example.com/index.html?url=" + encodeURIComponent(myUrl);

10.Serialization and deserialization (working with JSON)

var person = {name :'dev', age : 15, department : {ID : 21, name : "R&D"} }; 
var stringFromPerson = JSON.stringify(person); 
/* stringFromPerson is equal to "{"name":"Sachine","age":31,"department":{"ID":21,"name":"R&D"}}"   */ 
var personFromString = JSON.parse(stringFromPerson);  
/* personFromString is equal to person object  */
