Get Even Numbers Using Java Stream API

Java Stream API — Even Numbers (Full Screen) Java Stream API — Get Even Numbers Example 1 — Filter even numbers from a list Creates a list, uses Stream to filter evens, and prints them. Copy import java.util.*; import java.util.stream.*; public class EvenNumbersStream { public static void main(String[] args) { // Create a list of numbers List<Integer> numbers = Arrays.asList(1, 2, 3, 4, 5, 6, 7, 8, 9, 10); // Use Stream API to filter even numbers List<Integer> evenNumbers = numbers.stream() .filter(n -> n % 2 == 0) .collect(Collectors.toList()); // Print the even numbers System.out.println( "Even numbers: " + evenNumbers); } } Example 2 — Use IntStream.rangeClosed ...

Sum of two numbers in C++ Program without and with Class



In this C++ program we will calculate the sum of the two numbers and print the result, in the screen. The two numbers will be taken from the user.

input:

Two numbers. (i.e. 15,65 etc.)

output:

Sum of the given numbers will be printed on the screen.

CODE---->


#include<iostream>
using namespace std;
main()
{
int a,b,sum;
cout<< " \nEnter a Number : " ;
cin>>a;
cout<< "\nEnter another Number : " ;
cin>>b;
sum=a+b;
cout<< "\nThe sum of the Numbers is : " <<sum <<endl ;
system("pause") ;
}



Don't just read, write it, run it.....

RESULT:



With Class

#include<iostream>
using namespace std;
class sum
{
 private:
  int x,y;
 public:
  void get()
  {
   cout<<"Enter two numbers : ";
   cin>>x>>y;
  }
  void disp()
  {
   int c;
   c=x+y;
   cout<<"\nThe Sum of the numbers is : "<<c;
  }
};
int main()
{
 sum s;
 s.get();
 s.disp();
 return 0;
}
