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 ...

Multiplication of two Float numbers in C++ Language without and with Class

In this C++ program we will calculate the multiplication of two numbers(float) and print the result, in the screen. The two numbers will be taken from the user. input: Two numbers(float). (i.e. 15.4,2.4 etc.) output: Multiplication of the given numbers(float) will be printed on the screen. CODE----> #include<iostream> using namespace std; main() { float num1,num2,mul; cout << " \n      Enter a Number : " ; cin >>num1; cout << "\n      Enter another Number : " ; cin >>num2; mul=num1*num2; cout << "\n      The multiplication of the Numbers is : " << mul << endl ; system ("pause") ; } Don't just read, write it, run it..... RESULT : With Class #include<iostream> using namespace std ; class multi { private : float x , y ; public : void get () { cout << "Enter two num...

Difference between two numbers(float) in C++ Language without and with Class

In this C++ program we will calculate the difference between the two numbers(float) and print the result, in the screen. The two numbers will be taken from the user. input: Two numbers. (i.e. 15.6,65.7 etc.) output: Difference between the given numbers(float) will be printed on the screen. CODE----> #include<iostream> using namespace std; main() { float num1, num2, difference; cout << " \n Enter a Number : " ; cin >>num1 ; cout << " \n Enter another Number : " ; cin >>num2 ; difference = num1 - num2 ; cout \n The Difference between the Numbers is : " <<difference <<endl ; system (" pause ") ; } Don't just read, write it, run it..... RESULT : With Class #include<iostream> using namespace std ; class differ { private : float x , y ; public : void get () { cout << "Enter two numbers : " ; cin >> x ...

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

In this C++ program we will calculate the sum of the two numbers(float) and print the result, in the screen. The two numbers will be taken from the user. input: Two numbers. (i.e. 15.6,65.7 etc.) output: Sum of the given numbers(float) will be printed on the screen. CODE----> #include<iostream> using namespace std; main() { float a,b,sum; cout << " \n Enter a Number : " ; cin >>a; cout << " \n Enter another Number : " ; cin >>b; sum=a+b; cout \n The sum of the Numbers is : " <<sum <<endl ; system (" pause ") ; } Don't just read, write it, run it.....

Calculate the sum up to N numbers using Array in C-Language

In this C -program we will calculate the sum upto 'N' numbers using array. The numbers will be taken from the user. input: 'N' numbers.(i.e : 9,56,548) output: The sum of the given numbers will be printed on the screen. CODE----> #include<stdio.h> #include<stdlib.h> main() { int arr[50],i,n,sum=0; printf("       How many numbers you want to enter ?\n "); scanf(" %d ",&n); printf ("       Please,Enter the numbers : "); for ( i=0 ; i<n ; i++ ) {       scanf (" %d ",&arr[i]); } for ( i=0 ; i<n ; i++ ) {      sum=sum+arr[i]; } printf (" \n      The sum of the given numbers is : %d\n ",sum); system (" pause "); } Don't just read, write it, run it.....

Calculate sum of 5 numbers using Array in C-language

In this C -program we will scan the numbers using array and then we will calculate the sum of the given numbers, also using array. The numbers will be taken from the user. input: 5 numbers.(i.e : 5,6,9,56,548) output: The sum of the given numbers will be printed on the screen. CODE----> #include<stdio.h> #include<stdlib.h> main() { int arr[5],i,sum=0; printf ("       Enter Five numbers : "); for ( i=0 ; i<5 ; i++ ) {       scanf (" %d ",&arr[i]); } for ( i=0 ; i<5 ; i++ ) {      sum=sum+arr[i]; } printf (" \n      The sum of the given 5 numbers is : %d\n ",sum); system (" pause "); } Don't just read, write it, run it.....
