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 ...

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 Half Pyramid using *(Asterisk)

In this C program we will print a Pattern of Asterisks, called "Half-Pyramid" on the screen. * ** *** **** ***** input: The number of rows- The Range. output: The pattern will be printed on the screen. CODE----> #include<stdio.h> int main() {      int n,i,j;      printf( " Please, Enter the Range or the No. of Rows : " ) ;      scanf( " %d ",&n ) ;      for( i=1 ; i ; i++ )      {          for( j=1 ; j ; j++ )          printf( " * " ) ;          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 )  ...
