How do you count the number of words in a string?

Answer 1

To find the length of the string we use length method. The length property returns the length of a string (number of characters we use).The length of an empty string is 0.

For example:

function myFunction() {

var str = "Hello World!";

var n = str.length;

Hope this hepls.

Answer 2

Well, the length of any string in java can be measured as follows.

String s = "Example";

int len = s.length(); //the length() method calculates total no of chars in string s

System.out.println( "Length of the above string is " + len );

Answer 3

int countString(String word,String orginalString){

String delimiters = "+-*/(),. ";

StringTokenizer st = new StringTokenizer(orginalString, delimiters, true);

int count=0;

while (st.hasMoreTokens()) {

String w = st.nextToken();

if (w.equals(word)) {

result = ++;

}

return result;

}

}

Answer 4

This method returns the length of a string. The length is equal to the number of 16-bit Unicode characters in a strong. Syntax: public int length(). There is a Java input which can be used in order to determine the length of a string.

Answer 5

// Number of characters in String str:

str.toCharArray().length;

// or, more directly:

str.length();

Answer 6

CODE:

String a = "hello";

System.out.println(a.length());

OUTPUT:

5

Answer 7

In Delphi Pascal, it is:

var

s: string;

x: integer;

begin

s:='How many characters is this?';

x:=Length(s);

end;

Answer 8

declaration of number of characters in string[] e.g.

string[12];

string[21];

string[5];

declares 12,21, and 5 characters respectively

Answer 9

Use the strlen() function in the C standard library.

Answer 10

length() method in a String returns the number of characters in that String.

String s = "abc";

System.out.println(s.length()); // this outputs "3"
