Counting number of times a character is inputted

Question

I am trying to have my code output the exact number of times a certain character is said in an inputted sentence (For example e).

I tried using a char and for statement so its able to count but it gives me the wrong value

int countChar;
char e = '\0';
String str;
int count = 0;
System.out.println("input your sentence:");
str = in.next();

    for(i=0; i < str.length(); i++)
    {    if(str.charAt(i) == e)
            count++;
    }

    System.out.println(count);

Answer 1

You need to change if(str.charAt(i) == e) to if(str.charAt(i).equals("e")) , you don't really require a variable for this. You just require the quotation marks, and since you are comparing a string, you should use the above String.equals() method.

If you are looking for uppercase letters as well, use the || (OR) operator and do the same but replace the lowercase e with an uppercase

Answer 2

You should use 'e' instead of '\0' when comparing the characters
