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 ...
In this C-program we will Print the following Pattern made of asterisk(*). The no. of rows will be taken from the user.

input:
The number of rows.output:
The Pattern will be printed on the screen in the given range.CODE---->
#include<stdio.h>
#include<stdlib.h>
int main()
{
int i,j,k,n,space=0;
printf("Please, Enter the no. of rows : ");
scanf("%d",&n);
if(n<=0)
{
printf("Wrong input.");
exit(0);
}
for(i=n;i>0;i--)
{
for(k=space;k>0;k--)
printf(" ");
for(j=i;j>0;j--)
printf("*");
space=space+1;
printf("\n");
}
return 0;
}
~ The Space variable is actually used for new line.
