Hi Friend,

Try the following code:

import java.util.*;
class AverageLengthOfWords 
{
    public static void main(String[] args) 
    {
        int sum=0;
        Scanner input=new Scanner(System.in);
        System.out.print("Enter sentence: ");

        String st=input.nextLine();
        String str[]=st.split(" ");
        int len[]=new int[str.length];
        for(int i=0;i<str.length;i++){
            len[i]=str[i].length();
        }
        for(int i=0;i<len.length;i++){
        sum+=len[i];
        }
        int l=len.length;
        System.out.println("Avergae Length= "+(sum/l));


    }
}

Thanks
