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 Concatenation using strcat() function in C-Language

In this C program we will concatenate the source string at the end of the target string using strcat() fuction. The String will be given by the User. strcat() function concatenates the source string which is source_str in this program, at the target string which is target_str in this program. strcat() takes two arguements. Like : strcat(target_str,source_str); Learn about different string functions and their use: Different String Functions input: The String. output: The input string and the concatenated string will be printed on the screen. CODE----> #include<stdio.h> #include<string.h> int main () { char source_str [ 100 ], target_str [ 100 ]= "Hello " ; printf ( "Please, Enter the string: " ); gets ( source_str ); strcat ( target_str , source_str ); printf ( "\nSource String is: " ); puts ( source_str ); printf ( "\nTarget String is: " ); puts ( target_str ); return 0 ; } ...

String Copy without strcpy() in C-Language

In this C program we will copy the contents of a string into another without strcpy() 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 input string and the copied string will be printed on the screen. CODE----> #include<stdio.h> #include<string.h> int main () { int n = 0 ; char source_str [ 100 ], target_str [ 100 ]; printf ( "Please, Enter a string: " ); gets ( source_str ); while ( source_str [ n ]!= '\0' ) { target_str [ n ]= source_str [ n ]; n ++; } target_str [ n ]= '\0' ; printf ( "\nThe source string is: " ); puts ( source_str ); printf ( "\nThe copied string is: " ); puts ( target_str ); return 0 ; } Download the C-Program file of this Program.

String Copy using strcpy() in C-Language

In this C program we will copy the contents of a string into another using strcpy() fuction. The String will be given by the User. strcpy() function copies the contents of one string into another. The base addresses of the target and source strings should be supplied to this function. Means it take two arguements. 1 st is the target address (where the string will be copied) and 2 nd source address (from where the string will be copied). In this case target_str is the target and source_str is the source. Like : strcpy(target_str,source_str); Learn about different string functions and their use: Different String Functions input: The String. output: The input string and the copied string will be printed on the screen. CODE----> #include<stdio.h> #include<string.h> int main () { char source_str [ 100 ], target_str [ 100 ]; printf ( "Please, Enter a String : " ); gets ( source_str ); strcpy ( target_str , source_str...

Length of a String NOT using strlen() in C-Language

In this C program we will find the "Length" of a string. The String will be given by the User. Learn about different string functions and their use: Different String Functions input: The String. output: The Length of the String will be printed on the screen. CODE----> #include<stdio.h> #include<string.h> int main () { int n = 0 , len = 0 ; char arr [ 100 ]; printf ( "Please, Enter the String : " ); gets ( arr ); while ( arr [ n ]!= '\0' ) { len ++; n ++; } printf ( "\nThe length of the string is : %d" , n ); return 0 ; } Download the C-Program file of this Program. Don't just read, run on your pc !!! RESULT : Please, Enter a string : Hello World String Length is : 11 -------------------------------- Process exited after 11.28 seconds with return value 0 Press any key to continue . . .
