To add some additional information, the reason the second read doesn't appear to work is because read() just reads the next character in the stream. So, if you enter a name with more than 1 letter eg Henry, the first call to read gets the first letter 'H'. When you call read again it doesn't wait for you to enter a roll number because there is still 'enry\n' in the input stream so it gets the 'e' and continues. If you enter a single letter name it still doesn't work because pressing the Enter key adds a '\n' char to the stream so the second read gets that. As Campbell has said use readline() or better still use a java.util.Scanner.
