Question

JAVA

Can you make this return the first letter of  first and last name capitalized?

import java.io.File;
import java.io.IOException;
import java.util.*;
public class M1 {

   public static void main(String[] args) {
      
//scanner input from user
   Scanner scanner = new Scanner(System.in);
//
System.out.print("Please enter your full name: ");
String fullname = scanner.nextLine();

//creating a for loop to call first and last name separately

int i,k=0;
String first="",last="";
for(i=0;i<fullname.length();i++) {
char j=fullname.charAt(i);
if(j==' ') {
k=i;
break;
}
first=first+j;
}
for(i=k;i<fullname.length();i++) {
last=last+fullname.charAt(i);
}





System.out.println("First Name: " + first);
System.out.println("Last Name: " + last);
   }
}

CODE:

import java.io.File;
import java.io.IOException;
import java.util.*;
public class Main {

   public static void main(String[] args) {
    
    //scanner input from user
   Scanner scanner = new Scanner(System.in);
    //
    System.out.print("Please enter your full name: ");
    String fullname = scanner.nextLine();
  
    //creating a for loop to call first and last name separately
    int i,k=0;
    String first="",last="";
    for(i=0;i<fullname.length();i++) {
        char j=fullname.charAt(i);
        if(j==' ') {
            k=i;
            break;
        }

//converting first character to upper Case
        if(i==0){
            j = Character.toUpperCase(j);
        }
        first=first+j;
    }
  
    for(i=k;i<fullname.length();i++) {

//getting each character in j
        char j = fullname.charAt(i);

// Since, at kth position there is a space, So for k+1th position, Character case will be converted to upper Case
        if(i==k+1){
            j = Character.toUpperCase(j);
        }
        last=last+j;
    }
    System.out.println("First Name: " + first);
    System.out.println("Last Name: " + last);
   }
}
