The reversed string of the'coderolls.com' is: moc.slloredoc

In the`for` loop, I have assigned`blogName.length()-1` to i instead of`blogName.length()` because the characters in the string are indexed from 0.

I have given an image below to show the string indexing.


Also you can watch[the video on my youtube channel for reverse a string with the above method](https://www.youtube.com/watch?v=vrTYrQuB0BE).

In the`getBytes()` method of Java String first encodes the specified string into the sequence of bytes using the platforms default charset and then save the result in the byte array. The same byte array will be returned.

1. Using the`Integre.parseInt()` method

2. Using the`Integer.valueOf()` method

Now we will see the above ways to convert string to integer one by one.

When you are trying to convert a string to integer but your string contains a value other than the decimal digits, then bothe the methods (`Integre.parseInt()` method and`Integer.valueOf()` method) will throw the`NumberFormatException`.
