Java String class

Question

So we are given to write the exact output of the following code:

class stri123{

public static void main(String[] args) {

String name = "University Grants Commission";

boolean sword = true;

for(int i = 0; i < name.length(); i++){

if(sword)

System.out.println(name.charAt(i) );

if(name.charAt(i) = = '')

sword = true;

else

sword = false;

}

}

}

I coded this on NetBeans and found it is showing errors at the following lines(** represent error-indicating lines);

if(name.charAt(i) = = '') **

sword = true;

else **

sword = false;

What could possibly be the reasons for these errors and what is the exact output of the above code?

Answer 1

the compiler error is because you need to put a blank space in between the single quotes to check

for blank character.

when you do, it will print the first letter in each word,so the output is

U

G

C

note that the sword flag gets set to FALSE if the next character is not blank;

it doesn't get reset until the next white space character, which then causes the

first letter of the next word to print
