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 ...

Reverse a string with strrev() function in C Language

In this C program we will store a String in memory and Reverse it with the help of strrev() fuction. The String will be given by the User. Learn about different string functions and their use: Different String Functions input: The String. output: The Reversed String will be printed on the screen. CODE----> #include<stdio.h> #include<string.h> int main () { char str [ 100 ]; printf ( "Please, Enter the String : " ); gets ( str ); puts ( strrev ( str )); return 0 ; } Download the C-Program file of this Program. Don't just read, run on your pc !!! RESULT : Please, Enter the String : ProgramJoy.blogspot.com moc.topsgolb.yoJmargorP -------------------------------- Process exited after 34.15 seconds with return value 0 Press any key to continue . . .

Queue using Linked List in C-Language

In this C program we will perform Linear Queue operations using Linked List . input: The Choice(i.e Data insert, Data delete and Display) & The Number (integers) (i.e. for Data insert) (15,10,128 etc.) output: The Operations will be excecuted as choosen by the user. CODE----> #include<stdio.h> #include<stdlib.h> #include<malloc.h> typedef struct node { int data ; struct node * next ; } node ; node * rear = NULL ,* front = NULL ; void qinsert ( int value ) { node * getnode ; getnode =( node *) malloc ( sizeof ( node )); getnode -> data = value ; if ( rear == NULL ) { rear = getnode ; rear -> next = NULL ; front = rear ; } else { rear -> next = getnode ; rear = getnode ; rear -> next = NULL ; } } void qdelete () { node * delnode ; delnode = front ; if ( delnode == NULL ) printf ( "\n No elements to delete. Empty Queue." ); else if ( front == rear ) { printf ( "\n The val...

C-Program of Singly Linked List

In this C program we will perform operations on Singly Linked List ( i.e: Data insert Operations(at begining or at end or at any position), Data remove Operation(from begining or from end or from any position), Data Reverse Operation and display Operation ). The Choice( i.e: data insert,remove or display ) will be made by the user and The Number will be taken from the user( i.e: For Data insert Operation ). input: The Choice(i.e Data insert, remove, reverse or display) & The Number (integers) (i.e. for Data insert Operations) (15,10,128 etc.) output: The Operations will be excecuted as choosen by the user. CODE----> #include<stdio.h> #include<malloc.h> #include<stdlib.h> typedef struct node { int data ; struct node * next ; } node ; node * head = NULL ; node * getnode ( int x ) { node * n ; n =( node *) malloc ( sizeof ( node )); n -> data = x ; n -> next = NULL ; return ( n ); } void createlist () { int x ; ...
