Write a program in Java to accept a string in lower case and change the first letter of every word to upper case. Display the new string.
Sample input: we are in cyber world
Sample output: We Are In Cyber World
import java.util.Scanner;
public class RAnsariString
{
public static void main(String args[]) {
Scanner in = new Scanner(System.in);
System.out.println("Enter a sentence:");
String str = in.nextLine();
String word = "";
for (int i = 0; i < str.length(); i++) {
if (i == 0 || str.charAt(i - 1) == ' ') {
word += Character.toUpperCase(str.charAt(i));
}
else {
word += str.charAt(i);
}
}
System.out.println(word);
}
}
Enter a sentence:
We are in the cyber world
We Are In The Cyber World

First read the algorithm, then study the program code line by line. After that, compare the code with the output and finally go through the explanation. This approach helps learners understand both the logic and the implementation properly.
After understanding this example, try to rewrite the same program without looking at the code. Then change some values or logic and run it again. This helps improve confidence and keeps learners engaged on the page for longer.
