Displaying First Character Of Each Words Of A Sentence In Upper Case

The program is like: take a sentence and display starting characters in each words in upper case and the rest in lower case. This program is done in two techniques in BlueJ.

Import java.io.*;

class A

{

 String name,str;

 BufferedReader br=new BufferedReader(new InputStreamReader(System.in));

 int i,j;

 void take () throws Exception

 {

  System.out.println("Enter any sentence:");

  name=br.readLine();

  }

   void show()

   {

    i=1;

    while(true)

    {

    j=name.indexOf(' ');

    if(j< 0)<0 o:p="o:p">

    break;

    str=name.substring(0,j);

    name=name.substring(j+1);

    for(i=0;i< str.length();i++)

    {

     if(i==0)

      System.out.print(Character.toUpperCase(str.charAt(i)));

      else

       System.out.print(Character.toLowerCase(str.charAt(i)));

    }

    System.out.print(" ");

    }

    for(i=0;i< name.length();i++)

    {

     if(i==0)

      System.out.print(Character.toUpperCase(name.charAt(i)));

      else

       System.out.print(Character.toLowerCase(name.charAt(i)));

    }

    }

    public static void main(String args[])throws Exception

    {

     A ob=new A();

     ob.take();

     ob.show();

     }

     }

     

The same program is done using a different technique.

import java.io.*;

class A

{

 String name;

 BufferedReader br=new BufferedReader(new InputStreamReader(System.in));

 int i,j,f=0;

 void take () throws Exception

 {

  System.out.println("Enter any sentence:");

  name=br.readLine();

  }

   void show()

   {

   j=name.length();

   for(i=0;i< j;i++)

   {

    if(i==0)

      System.out.print(Character.toUpperCase(name.charAt(i)));

      else if(name.charAt(i)==' ')

      {

       System.out.print(" "+Character.toUpperCase(name.charAt(i+1)));

       i++;

       }

       else

       System.out.print(Character.toLowerCase(name.charAt(i)));

      }

     }

    public static void main(String args[])throws Exception

    {

     A ob=new A();

     ob.take();

     ob.show();

     }

     }
