This is a java program to enter a sentence and show the words with maximum and minimum vowels in it. In case of numbers of words with same feature, the first one will be displayed.

import java.util.Scanner;

class Star

{

String str1,s,maxs,mins;

int maxl=0,minl,j;

Scanner sc=new Scanner(System.in);

public void take()

{

System.out.print("\nEnter the sentence:");

str1=sc.nextLine().trim();

str1=str1+ " ";

minl=str1.length();

while(true)

{

 int i=str1.indexOf(' ');

 if(i< 0)

 break;

 s=str1.substring(0,i);

 j=countVowels(s);

 if(j >=maxl)

 {

     maxl=j;

     maxs=s;

    }

    if(j< minl)

 {

     minl=j;

     mins=s;

    }

    str1=str1.substring(i+1);

}

 System.out.println("\nWord With Maximum Vowels = "+maxs);

 System.out.println("\nWord With Minumum Vowels = "+mins);

}

public int countVowels(String s)

{

s=s.toUpperCase();

int i,len,c=0;

len=s.length();

for(i=0;i< len;i++)

{

 switch(s.charAt(i))

 {

      case 'A':

      case 'E':

      case 'I':

      case 'O':

      case 'U':

      c++;

      break;

    }

}

return c;

}

public static void main(String args[])

{

 Star ob=new Star();

 ob.take();
