In C/C++ a semicolon is used to terminate the statement.But if,while,switch(conditional constructs) do not require a semicolon to terminate.So if we use the printf statement inside these conditional constructs,then we do not require any semicolon to terminate the statement.

import java.util.*; class countLetters {     public static void main(String s[])     {         Scanner sc = new Scanner(System.in);         int count = 0;         char ch;                 System.out.println("Enter The String To Count No. Of Letters :  ");         String str = sc.nextLine();                 for(int i=0;i<str.length();i++)         {                 ch = str.charAt(i);                 if(ch!=' ')                 {                     count++;                 }                         }         System.out.println("The no of letters in given string is : " + count);     } }
