Meet Jancy, a diligent student learning to master programming. She is working on a project that requires her to process text data. Today, she needs to convert a given string to lowercase to ensure consistent and uniform text.
Write a program that takes an input string and converts it to lowercase to help out Jancy.
Input format :
The input consists of a single line of string.
Output format :
The output prints the input string converted to all lowercase letters.
Refer to the sample output for formatting specifications.
Code constraints :
The input string will consist of at most 1000 characters.
The string may contain letters(uppercase and lowercase), digits and special symbols.
Sample test cases :
Input 1 :
HeLLo WoRLd!
Output 1 :
hello world!
Input 2 :
It's a BeAutiful DAY
Output 2 :
it's a beautiful day
import java.util.Scanner;
public class TextConverter {
public static void main(String[] args) {
Scanner scanner = new Scanner(System.in);
// Read the input string
String input = scanner.nextLine();
// Convert to lowercase
String lowercaseString = input.toLowerCase();
// Print the result
System.out.println(lowercaseString);
scanner.close();
}
}
Ariana, a budding programmer, is working on a string manipulation task where she needs to replace all occurrences of a specific character with another character in a given string.
Her goal is to practice her string manipulation skills and accomplish this task.
Input format :
The first line of input consists of the string.
The second line consists of a character, representing the target character to be replaced.
The third line consists of a character, representing the replacement character.
Output format :
The output prints the modified string after replacing all occurrences of the target character with the replacement character.
Refer to the sample output for formatting specifications.
Code constraints :
The input string contains both uppercase and lowercase with at most 100 characters.
Sample test cases :
Input 1 :
Hello, World! o x
Output 1 :
Hellx, Wxrld!
Input 2 :
Jurassic Park s $
Output 2 :
Jura$$ic Park
Input 3 :
Onion O k
Output 3 :
knion
import java.util.Scanner;
public class StringReplacer {
public static void main(String[] args) {
Scanner scanner = new Scanner(System.in);
// Read input string
String inputString = scanner.nextLine();
// Read the target character to be replaced
char targetChar = scanner.next().charAt(0);
// Read the replacement character
char replacementChar = scanner.next().charAt(0);
// Replace all occurrences of targetChar with replacementChar
String modifiedString = inputString.replace(targetChar, replacementChar);
// Print the modified string
System.out.println(modifiedString);
scanner.close();
}
}
