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 ...

Bubble Sorting in C Language

In this C program we will sort(in ascending order) some elements and print the sorted order of the Array of elements, in the screen. The Number of elements to be entered in the Array will be taken from the user and also the values of the elements. input: The number of elements(integers) (i.e. 5,10,7 etc.) & the values of the elements(integers) (i.e. 51,10,74 etc.). output: The sorted(in Ascending Order) numbers will be printed on the screen. CODE----> #include<stdio.h> int main () { int a [ 50 ], n , i , j , t ; printf ( " Please, Enter the number of elements : " ); scanf ( "%d" ,& n ); for ( i = 0 ; i < n ; i ++) { printf ( "\n Please, Enter data : " ); scanf ( "%d" ,& a [ i ]); } for ( i = 0 ; i < n - 1 ; i ++) { for ( j = 0 ; j <= n - i - 1 ; j ++) { if ( a [ j ]> a [ j + 1 ]) { t = a [ j ]; a [ j ]= a [ j + 1 ]; a [ j + 1 ]= t ; } } } print...

C-Program of Printing Half Pyramid using 123(Numbers)

In this C program, we will print a Pattern of Numbers, called "Half-Pyramid" on the screen. The Range(i.e : No. of Rows) will be taken from the user. 1 1 2 1 2 3 1 2 3 4 1 2 3 4 5 input: The number of rows- The Range. output: The pattern will be printed on the screen. CODE----> #include<stdio.h> int main () { int i , j , n ; printf ( " Please, Enter the Range : " ); scanf ( "%d" ,& n ); for ( i = 1 ; i <= n ; i ++) { for ( j = 1 ; j <= i ; j ++) { printf ( "%d " , j ); } printf ( "\n" ); } return 0 ; } Don't just read, write it, run it.....

C-program of printing "Hello World", 10 times on the screen.

In this C program we will print "Hello World", 10 times on the screen. We will use "body-less-loop" for this C-Program. "Body-less-loop" : it means that the inner part(code block to be executed) of the loop will be empty and the loop will have a semi-colon(;) in it's end. i.e: for ( .....  ; .....  ; .....  ) ; input: Null. output: "Hello World" will be printed on the screen, 10 times. CODE----> #include<stdio.h> int main() {      int i;      for( i=1 ; i ;printf( "   Hello World ! \n ", i++ )) ;      return 0 ; } Don't just read, write it, run it..... RESULT :

C-Program Of "Finding the LARGEST Number among 3 numbers and Checking all the possible Conditions."

In this C program we will check the 3 numbers and find the Largest number among them. We will also check all the possible conditions (i.e: if there is more than one Largest number exists, means two numbers which has equal values and larger than the third number, it will be shown in this Program and if all the numbers has same value, then, it will be also shown in this Program. The three numbers(integers)(i.e: 55, 64, 11) will be taken from the user. input: The three numbers(integers)(i.e: 55, 64, 11) output: The Largest number(s) will be printed on the screen. CODE----> #include<stdio.h> int main() {    int a,b,c;    printf( " Enter the values of 3 numbers : " ) ;    scanf( " %d%d%d ", &a,&b,&c) ;    if( a>b )    {      if( a>c )      printf( " \n The First Number is Largest : %d ",a ) ;      else if( a==c )  ...

C-Program of XOR calculation(2 bit)

In this C program we will calculate the XOR function between two bits(i.e: 0 or 1) and print the result, in the screen. The two bits(i.e: 0 or 1) will be taken from the user. Discussion: The XOR gate (sometimes EOR gate, or EXOR gate and pronounced as Exclusive OR gate) is a digital logic gate that gives a true (1 or HIGH) output when the number of true inputs is odd. An XOR gate implements an exclusive or; that is, a true output results if one, and only one, of the inputs to the gate is true. If both inputs are false (0/LOW) or both are true, a false output results. XOR represents the inequality function, i.e., the output is true if the inputs are not alike otherwise the output is false. A way to remember XOR is "one or the other but not both".(from Wikipedia ) For full article click here . input: The two bits(i.e. 0 or 1) output: The XOR of the bits will be printed on the screen. CODE----> #include<stdio.h> #include<conio.h> main() ...

WhatsApp Application Crashing

In this Post , we will discuss about the new spam message , which has recently started circulating via whatsapp and it is making everyone’s whatsapp application crashed... A new spam message has recently started circulating via whatsapp that is making everyone’s whatsapp application crashed when they’re clicking on the message that is something like – “if you touch the black point then your whatsapp will hang..don’t touch here”.(See pic1) pic1 For understanding the reason, you’ll need to have a basic knowledge about ASCII values. Typically ASCII decimal number is created from binary, which is the language that all computers understand. Each alphabet has its own ASCII value (i.e: "A" has a ASCII value of 065). So if you send a text message on whatsapp, the system first breaks down each and every alphabet into ASCII characters. But there’s a limit in the numbers of text (ASCII values) that you can send via a single message in whatsapp messenger. Whatsapp encount...
