Java – Number of Times a Word has Been Mentioned | Java Example

Algorithm for Number of Times a Word has Been Mentioned :

step 1: read String w
step 2: read String w1
step 3: set len=w1.length()
step 4: set result=0

step 5: If len> 0 then executes following steps else goto step-10
step 6: Set start =w.indexof(w1, start+len)
step 7: repeat through step-9 while(start 1= -1)
step 8: result= result+ 1
step 9: start = w. indexof(w1, start+ len)
step 10: print result
step 11: Exit

Here is the Java Example for – Number of Times a Word has Been

import java.util.*; 
 import java.io.*; 
 public class WordCount  
 { 
                         public static void main(String args[]) 
               { 
                        System.out.print("Please Enter the Sentence : "); 
                        Scanner Word=new Scanner(System.in); 
                        String Count=Word.nextLine(); 
                        System.out.print("Please Enter the Word : "); 
                        String wl=Word.nextLine(); 
                        int len=wl.length();  
                        int CountWord =0; 
                        if(len> 0) 
                           { 
                               int start = Count.indexOf(wl); 
                                    while(start!=-1) 
                                           { 
                                                CountWord++; 
                                                start=Count.indexOf(wl,start+len); 
                                           } 
                            } 
                                  System.out.println(CountWord); 
                } 
 }
