import java.io.*;

import java.util.Scanner;

class ChangeLetter {

public static void main(String args[ ]) throws IOException {

Scanner sc = new Scanner(System.in);

System.out.print(“Enter String in lowercase:”);

String str 1 = sc.next( ); strl = “” +strl;

String str2 = ” “:

for (int i = 0; i<strl.lenght(); i+ +) {

if(strl ,charAt(i) = = “) {

str2 = str2 + ” +Character.

toUpperCase(strl.charAt(i+l)); i+ + ;

else str2= str2 + strl.charAt(i);

}

System.out.println(str2.trim( ));

}
