Assignment practices java classes in the java.io package that process text and binary files.

Please note:

The BufferReader class's readLine method returns a line from a file as a String. If you need to perform calculations, you will need to convert the String object into a number. You can use a wrapper class to convert.

These methods are:

Methods Purpose Example

Integer.parseInt Convert a String to an int int num=Integer.parseInt(str)

Double.parseDouble Convert a String to a double double num=Double.parseInt(str)

Byte.parseByte Convert a String to a byte byte num=Byte.parseByte(str)

Float.parseFloat Convert a String to a float float num=Float.parseFloat(str)

Long.parseLong Convert a String to a long long num=Long.parseLong(str)

Short.parseShort Convert aString to a short short num = Short.parseShort(str)
