[gaurisharma]

Sir your explanation is just great....do u teach python, JavaScript too??

[nikhilkumargiri]

Can I valid for user input.i was trying this but only the letter before the string was converting.

[umarwani]

But sir without using a condition for white spaces, still we r getting the desired output.
32-32=0
And char value of 0 is null..
Then why it is showing space

[muhammadsibtain]

Sir by charAt(i) we can access the string char by using for loop

[mopurinandini]

Sir, how to find the string length, if the input should be taken by a user.it can be a sentence only with alphabets and spaces, no special characters are allowed, I tried some methods Sir, but its showing the length of only first word before space

[madhupreethi]

Sir can't we use replace() for spaces other than if comdition?

[GulbargaRamNavamiUstav]

Hello sir... while converting from uppercase to lowercase output is showing '@' symbol at spaces... whats the issue sir?

[maksaini]

if(y[i]! =' ') invalid character constant error is coming what is the way to solve it.

[ankitshrivastava]

This will also give the same output
while(i!=arr.length)
{
if(arr[i]==' ')
{
System.out.print(arr[i]);
i++;
}
arr[i]= (char) (arr[i]-32);
System.out.print(arr[i]);
i++;
}
}
