import java.io.*;

class abc

{

public static void main() throws IOException

{

InputStreamReader ir=new

InputStreamReader(System.in);

BufferedReader br=new BufferedReader(ir);

String str, word, wrd=“ ”; char ch; int c=0;

System.out.println(“Enter A sentence”); str=br.readLine( );

str=str.trim( );

System.out.println(“Enter a word to be searched”); word=br.readLine( );

str=str + “ ”;

for(int i=0; i<str.length(); i++)

{

ch=str.charAt(i);

if (ch! = ‘ ’)

{

wrd=wrd+ch;

}

else

{

if(word.equals(wrd))

{

c++;

}

wrd=“ ”;

}

System.out.println(“searched word occurs”+c);

}
