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 ...

String Compare using strcmp() function in C Language

In this C program we will compare two strings using strcmp() fuction. The Strings will be given by the User. strcmp() function compares two strings in this program, if two strings are identical (i.e: "Hello" and "Hello" are identical), then the function returns a integer value Zero " 0 " else, it returns a non-zero value. If it returns -1 then it means, the first mis-match occured between a Higher-case and a Lower-case value.(i.e: A pple and a pple) If it returns +1 then it means, the first mis-match occured between a Lower-case and a Higher-case value.(i.e: a pple and A pple) Obviously the function strcmp() is case-sensitive. strcmp() takes two arguements. Like : strcmp(string1,string2); Learn about different string functions and their use: Different String Functions input: The two Strings. output: The strings are identical or not, will be printed on the screen. CODE----> #include<stdio.h> #inc...

String Concatenation without using strcat() function in C Language

In this C program we will concatenate two strings without using strcat() fuction. The Strings will be given by the User. If gets() function doesn't working for you, change the gets() lines by scanf("%[^\n]%*c", str1); and scanf("%[^\n]%*c", str2); Learn about different string functions and their use: Different String Functions input: The Strings. output: The concatenated string will be printed on the screen. (i.e: First string + Second string) CODE----> #include<stdio.h> #include<stdlib.h> void STRCAT ( char * s1 , char * s2 ) { while (* s1 != '\0' ) { s1 ++; } while (* s2 != '\0' ) { * s1 =* s2 ; s1 ++; s2 ++; } * s1 = '\0' ; } int main () { char str1 [ 100 ], str2 [ 100 ]; printf ( "Please, Enter the First String: " ); gets ( str1 ); printf ( "Please, Enter the second String: " ); gets ( str2 ); STRCAT ( str1 , str2 ); printf ( "After conc...
