Capitalize a String in Java ~ foundjava

An example on making the characters after the space capital if they are not, in Java. Here is a logic that i've written and that's what i can do. Still more efficient logics are appreciated in the comments. Thanks and go ahead. The [main logic] will also work in any programming language.

Let's capitalize!

import java.util.*;
class CapitalizeString
{


 public static void main(String args[])
 {


 // Create Scanner object for taking input from the user

 Scanner s=new Scanner(System.in);


 // Read a string from the user and store it in st

 String st=s.nextLine();
 

 // Convert string to char array

 char[] c=st.toCharArray();
 
 
  // Loop till end of the char array

  for(int i=0;i<c.length;i++)
  {

   
   // If char at index i is a space, then..
   if((c[i]==' '))
   {
   
    
    // If the character after space is a small alphabet i.e. ascii values of a-z are from 97-122
    
    if((c[i+1]>=97)&&(c[i+1]<=122))
    {


    /*


    At that position put capital of that alphabet,
    ascii values of A-Z are 65-90, so for every
    particular small and capital alphabet there is a difference of 32
    Also typecast to char from int.

 
    */

    c[i+1]=(char)(c[i+1]-32);


    }


   }

   
   // Make even the first letter capital
   else if(i==0)
   {

    
    // The same as above, but for the current char [first char]

    if((c[i]>=97)&&(c[i]<=122))
    {


    c[i]=(char)(c[i]-32);


    }


   }


  }


 // Show it to the user

 System.out.println("Capitalized: "+new String(c));

 
 }


}

I think every thing is clear as every statement is explained above, so it will be useful for the future reference too. Go ahead with the output.

Output

gowtham gutha
Capitalized: Gowtham Gutha

Note: No problem if spaces occur, they do not change. If you have any try trimming the spaces by calling st.trim() here and then convert it to char[]. The code might look like this.

Change, char c[]=st.toCharArray(); to

char c[]=st.trim().toCharArray();
