Hello...how do i count characters in the sentence...example i write in console with space or .?-() then it output us count

Answer 1

It depends. If you need an algorithm, i'll to show you, but else you can use the length function.
Exemple:
String sentence = "Hello World";
int length = sentence.length();
Else, if you need an algorithm, call this function in your main and pass sentence in parameter. :)
public static int length(String str)
{
int i = 0;
str += '\n';
while(str.charAt(i) != '\n')
{
i++;
}
return i;
}
