//Program to find word count in a given text

import java.util.*;
class wcount
     {
   public static void main(String args[])
      {
    String s;
    int i,w=1;
    System.out.println(" Enter text : ");
    Scanner obj=new Scanner(System.in);
    s=obj.nextLine();
    char a[]=s.toCharArray();
    if(a.length==0)
       w=0;
    else
      {
    for(i=0;i<a.length;i++)
       {
        if(a[i]==' '||a[i]=='\0')
            w++;
       }
      }
    System.out.println("\n Word count is : "+w);
    System.out.println();
     }
}

The Output will be similar to this
