String Programs part 5

1. Write a program to extract words of a sentence and calculate the potential of the words, print the words with their potential(Potential is the sum of the ASCII values of each letter of the word)

import java.io.*;
class WordPotential
{
    public static void main()throws IOException
    {
        BufferedReader br=new BufferedReader(new InputStreamReader(System.in));
        System.out.println("Enter a sentence");
        String str= br.readLine();
        str=str+" ";
        str=str.toUpperCase();
        int len=str.length(); 
        int d=0; int sum=0;
       System.out.println("Word "+ "\t"    + "Potential" );
       for (int i=0;i<len;i++)
        {
            char ch=str.charAt(i);
            if(Character.isWhitespace(ch))
            {
                String temp=str.substring(d,i);
                Temp=temp.trim();
                int len2=temp.length();
                for(int j=0;j<len2;j++)
                {
                    char ch1=temp.charAt(j);
                    sum+=(int)ch1;
                }              
                System.out.println(temp+"\t "+sum);;sum=0;d=i;
            }
        }
    }
Output:
Enter a sentence
This is India
Word 	Potential
THIS	 312
IS	 156
INDIA	 357

2. Write a program to input a word and encrypt it. Each consonant of the word should be replaced with its next letter in the alphabet , and all the vowels will  be converted to capital letters

import java.io.*;
class Extract
{
    public static void main()throws IOException
    {
        BufferedReader br=new BufferedReader(new InputStreamReader(System.in));
        System.out.println("Enter a word");
        String wrd= br.readLine();
        int len=wrd.length();
        for (int i=0;i<len;i++)
        {
            char ch=wrd.charAt(i);            
            switch(ch)
            {
               case 'a':
               case 'e':
               case 'i':
               case 'o':
               case 'u':
               case 'A':
               case 'I':
               case 'E':
               case 'O':
               case 'U':
               wrd=wrd.replace(ch,Character.toUpperCase(ch));
               break;
               default:
               wrd=wrd.replace(ch,++ch);               
               break;              
            }
        }    
        System.out.println(wrd);
    }
}
Output:
Enter a word
