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

[@umarwani4810]

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

[@ashwinilohar1169]

same doubt I also have .

[@muhammadsibtain4855]

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

[@madhupreethi8554]

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

[@ABCforTechnologyTraining]

replace() method is designed to "Replace" all occurrences of the old sequence of characters with the new sequence of characters. Please note, in our case, we are not supposed to REPLACE the spaces with any other character in the output, instead, spaces should be RETAINED as it is in the output. Hence if condition will ensure to skip the spaces for case conversion without replacing them with any other character/s.

[@maksaini7515]

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

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

[@GulbargaRamNavamiUstav]

ASCII value for space is 32 and for that y(i)+32 is 64 ascii value means it is giving @ result at space... if we want space than what we do sir

[@ankitshrivastava1772]

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++; } }
