Java Question

What are the features of Java 8?

Accepted Answer

Java 8 provides following features for Java Programming :

1. Lambda expression helps us to write our code in functional style. It provides a clear and concise way to implement SAM interface(Single Abstract Method) by using an expression. It is very useful in collection library in which it helps to iterate, filter and extract data.

2. An Interface that contains only one abstract method is known as functional interface. It can have any number of default and static methods. It can also declare methods of object class. Functional interfaces are also known as Single Abstract Method Interfaces (SAM Interfaces).

3. Java introduced a new class Optional in Java 8. It is a public final class which is used to deal with NullPointerException in Java application. We must import java.util package to use this class. It provides methods to check the presence of value for particular variable.

4. Java has introduced a new Date and Time API since Java 8. The java.time package contains Java 8 Date and Time classes.

5. Java provides a facility to create default methods inside the interface. Methods which are defined inside the interface and tagged with default keyword are known as default methods. These methods are non-abstract methods and can have method body.

Accepted Answer

As a fresher, I am interested in learning new thing as a student I learn things the theoretically but I am waiting for an opportunity to implement then in a partical way ,if you will hire me I will do my best.

public class PrimeExample{    
 public static void main(String args[]){    
  int i,m=0,flag=0;      
  int n=3;//it is the number to be checked    
  m=n/2;      
  if(n==0||n==1){  
   System.out.println(n+" is not prime number");      
  }else{  
   for(i=2;i<=m;i++){      
    if(n%i==0){      
     System.out.println(n+" is not prime number");      
     flag=1;      
     break;      
    }      
   }      
   if(flag==0)  { System.out.println(n+" is prime number"); }  
  }//end of else  
}    
}
