I am working on a program that will count words that is typed or pasted in the text area. It counts the words correctly if it doesn't have a double space. I use the split method for this and uses the for loop for objects to count the words.

here is the simplest form of the part of the code that got some problem...

public static void main(String[] args) {
        String string = "Java  C++ C#"; //i put double space after the word Java
        String[] str;
        int c=0;
        str = string.split(" ");
        for(String s:str){
            if(s==" ")
                System.out.println("skipped space");
            else{
                System.out.println("--"+s);
                c++;
            }
        }
        System.out.println("words; " + c);
    }

im trying to check if the string contained in the object s is a space but how I do it didn't work.
I want it to output like this

--Java
skipped space
--C++
--C#
words; 3

but the result is

--Java
--
--C++
--C#
words; 4

Any Suggestions on how can i solve this? or which part i got a problem?
thanks in advance.

When you compare a string, you shouldn't use equals sign. You should replace if(s==" ") with if(s.equals(" ")) or if(s.equalsIgnoreCase(" ")).

just the same result .... it still don't enter the if statement when there was a space stored in the string

Remember that split(" ") will split on every space.
You won't have any tokens that are equal to " " instead they will be empty if there are multiple spaces

public class Snippet {
	public static void main(String[] args) {
	        String string = "Java  C++ C#"; //i put double space after the word Java
	        int c=0;
	        String[] str = string.split(" ");
	        for(String s:str) {
	            if(s.equals(""))
	                System.out.println("skipped space");
	            else{
	                System.out.println("--"+s);
	                c++;
	            }
	        }
	        
	        System.out.println("words; " + c);
	    }
}
