A lambda expression, introduced in Java 8 is similar to a block of code resembling an anonymous function that can be passed to constructors or methods for execution as an argument.

Examples:

a)() -> System.out.println("Hello Lambda")
b)
(int x) -> 3
x -> {
System.out.println(x + 2);
return x +3;
}

In the first example :

() identifies the lambda's parameter list (there are no parameters),

 -> indicates that the expression is a lambda

System.out.println("....") is the code to be executed which prints the string "Hello Lambda".

In the Second Example:

(x) identifies the lambda's parameter list (x is an input parameter),

 -> indicates that the expression is a lambda

System.out.println("....") is the code to be executed which calculates the value of x + 2 and prints it. Also assigns a value of x+3 = 6 to variable x which had an initial value of 3.

A class provides the blueprints for objects. So basically, an object is created from a class. That can be used anywhere as you wish.

Dear Sandeep,

You have asked a question that many people ask, and it shows that you have the curiosity in your mind to learn. This era of technology has made it possible for quality courses to be accessible by all. If you want to learn design, code and Data structure, I would suggest taking classes on coding and data structure from the YouTube channel Code With Harry. The courses are for free and are in Hindi. I have referred it to many others, and most of them have been benefited from it.

I wish you luck.

Angular 4 is the latest version of Angular. Although Angular 2 was a complete rewrite of AngularJS, there are no major differences between Angular 2 and Angular 4. Angular 4 is only an improvement and is backwards compatible with Angular 2.

How do I fetch data from MySQL in React Native and PHP using a search engine?

Arunava Biswas

bored of old-schooled teaching? let me show you the millenial way..

this.is my php file: $con = mysqli_connect($HostName,$HostUser,$password,$db); // Getting the received JSON into $json variable. $json = file_get_contents('php://input'); // decoding the received JSON and store into $obj variable. $obj = json_decode($json,true); // Populate ID from JSON $obj... read more

this.is my php file:

$con = mysqli_connect($HostName,$HostUser,$password,$db);

 // Getting the received JSON into $json variable.
 $json = file_get_contents('php://input');

 // decoding the received JSON and store into $obj variable.
 $obj = json_decode($json,true);

 // Populate ID from JSON $obj array and store into $ID.
$ID = $obj['numero'];

//Fetching the selected record.
$CheckSQL = "SELECT origine FROM envoi WHERE numero='$ID'";

$result = $con->query($CheckSQL);

if ($result->num_rows >0) {
 while($row[] = $result->fetch_assoc()) {
 $Item = $row;
 $json = json_encode($Item);
 echo $json;
 }
}
else {  
 $EmailExistMSG= "No Results Found.";
 $EmailExistJson = json_encode($EmailExistMSG);
 echo $EmailExistJson ; 

}

And this is my react native script where i should enter number and fetch his data if it's exist in my database:

search= () =>{
     //alert('ok');
     const {numero}=this.state;

     fetch('http://192.168.1.4:80/search.php',{
     method:'post',
     header:{
     'Accept':'application/json',
     'Content-type' :'application/json'
     },
     body:JSON.stringify({numero:numero})}).then((responseData)=>responseData.json()).then((responseJson)=>{alert(responseJson)}).catch((error)=>{console.error(error);})}

  render(){
    return(

          <View style={styles.pass}>
          <TextInput placeholder="Saisir le numéro de suivi de l'envoi"   onChangeText= {numero=>this.setState({numero})}/>
          <TouchableOpacity onPress={this.search} style={{marginTop:20,marginLeft:70}}>
          <Icon name="search"  size={20}/>
          </TouchableOpacity>
          </View>

    )
