class ABC {
public static void main( String args[])
{ String x="we are proud to ABCians "
String y[]= x.split(" ");
System.out.println(y.length);
}
}😍😍

String[] arr = { "ABC", "CDE", "TRE" };
Stream<String> stream = Arrays.stream(arr);
long i=stream.count();
System.out.println(i);

Sir without using split method how to do this

[jaspreetsingh-nhkn]

Not works well when first word is started with a space .

[dennismc]

Bro this was one of the best java videos ever!

[sudarshan]

Another way of writing the program without using split function


class CountWords
{
public static void main(String[] args)
{
String s="WE ARE PROUD INDIANS";
char y[]=s.toCharArray();
int size=y.length;
int i=0;
int count=1;
while(i!=size)
{
if(y[i]==' ')
{
count++;
}
i++;
}
System.out.println("The number of words in the sentence: "+count);
}
}

import java.util.Scanner;

//My code solves all the testcases:

public class countWords {

public static void main(String[] args) {
// TODO Auto-generated method stub

System.out.println("Enter a string:");
Scanner scan = new Scanner(System.in);
String str = scan.nextLine();
//When we are giving this regex pattern, it considers all the extra spaces which can come in between words as well.If you give only (" ") any extra space will be considered as a word..so give the regex pattern.
String y[] =str.split("\\s+");

//If the string you give as input starts with space, it will be considered as a word as well.. so we must subtract minus 1 from length to counter it.
//So total 3 cases:
//1.NormalCase: Words have one space in between them will be executed by the else statement.
//2.Case2: Words starting with space will be executed by the if code.
//3.Case3: Words having more than just a single space between them..is already covered when we give the regex pattern.

if(str.startsWith(" ")) {

}
else {

}
