Hi, Sir would care to explain about second loop statement. why you are using both equal and non-equivalent character.
s=hello world yokesh
here, s[0] has what? hello
is it blank space? no
thus if s[0]!=blank space u incr count
next word= s[1] = blank space
next = s[2] = world
is it a blank space? no
count incr
thus if s[i]= blank space ..imagine i as 1
and if s[i+1]= not a blank space
u gotta incr count
get it?
How to integrate list of map of string, string
Bro adding a space at the end "I am Robot " will produce wrong results. You can use trim to remove spaces at the start and the end.
🙌🏼thank you
import java.util.*;
public class java{
public static void main(String[]args){
Scanner scan=new Scanner(System.in);
String a =scan.nextLine();
String[] arr=a.split(" ");
System.out.println(arr.length);
}
}
In interviews they will tell you not to use inbuilt functions
@@P_Nut07Then we can iterate through the array to get the length. Isn't it??
public class NoOfWordsinString {
public static void main(String[] args) {
// TODO Auto-generated method stub
String k="aajhfwef wuihfuiwhfuiwhf fuwhuiwhf iuhiuwhf ";
int count=0;
if((k.charAt(0)!=' '&&k.charAt(1)==' ')||k.indexOf(' ')>1 ) {
count++;
}
for(int i=0;i
