     1. import  java.io.*;

  32.                        if(x.equals(x2))  
  33.                         System.out.println(x);

  35.                       
  36.              }  
  

what i am trying to do here, is to make it possible for the user to type 2 lines, and then say(or display) whether the string of the first sentence correspond to the string of the second sentence.

so for example:

first sentence:
i will go shopping

second sentence:
Tomorrow, i will go swiming.

" i will go" corresponds in the second sentence. so how can i make the program look for corresponding words, and identify them?

so far , i have written this. but i dont know how to finish.

If you're looking for corresponding words, then I would not bother with individual chars. I would probably use String's split method to break the input into words, then write a method to compare sequences of these words using String's equals (or equalsIgnoreCase) method. Do not use ==.

If you do it by character by character, then you'll end up with meshed code. Because, for example, in your first sentence, there is a char i, so you search for i in the second sentence, It's OK. But how do you put a space between the next word? And, for the second character w, there is a w in your first sentence's word Tomorrow. then?.....

It's better to go for checking word by word,,,,,

the problem comes when the user might write a sentence with 100 ways. i cant compare all his words using loops or for methods.


i thought to make two variables

string end= " "

String Word= end+Str.charAt() + end

but how can i number each variable and make it look at the second string with no problem

 import java.io.*;
class Ex11
{

              public static void main(String[] args)
             {       
                    Console console=System.console();
                    System.out.println("please write a sentence"+" ");
                    String Str;
                    Str=console.readLine();
                   

                    System.out.println("please write another sentence"+" ");
                    String Str2;
                    Str2=console.readLine();
                    
                        
                     
                     for(int i=0; i<Str.length(); i++){
                     for(int j=0; j<Str2.length(); j++){
                     if(Str.charAt(i)==Str2.charAt(j)){
                     char Str3;  
                     Str3 += Str.charAt(i);
                     System.out.println(Str3);
                   
                         }
                       }
                
                       
                         }
                     
                       
                      

                    
             }
}


        

i also came up with this one. but it tells me that St3, failed to initialize. how do i fix it and why is it caused?

I think you can. But you need to be very careful about defining your algorithm -- the logical process you will use. Try writing this out step by step in Engligh before trying to code it.

but if " " character, i cant tell java to stop counting words before that space, can i ?


is there a way i could make java count all characters till " ", and then add all that character string to a variable called Word. then make java pass onto another String (after " ") find its characters till it reaches " ",
and add it to a word?
another variable
Words=Word+Words


is this direction possible? can it be done?
