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 understand the algorithm carefully. Then study the program line-by-line and compare it with the output. Finally, review the explanation section to strengthen your logic and programming understanding.
Rewrite the program without looking at the code. Modify values, conditions or logic and run it again. This helps improve confidence and strengthens coding skills much faster.
