Chapter 10.4, Problem 29STQ

Program Plan Intro

Program plan:

• Import the required header files.
• Define the class “ReadFile”.
• Define the main method.
  • Declare the string variable along with the value.
  • Inside the “try” block, the “ObjectInputStream” is used to read a data from the binary files.
    • The “inputStream” is the object of the “ObjectInputStream” stream class.
    • The “FileOutputStream” is an output stream used for reading a data from a “File”.
    • It allows to open a file “temperature.dat” for reading binary data and to establish the connection within it.
    • Inside another “try” block, read the double values from the binary file and display it.
    • This method reads only three numbers when it goes to next one the “EOFException” is thrown. The “EOFException” class can be used to test for the end of a file.
  • The “FileNotFoundException” catch block is used to throw an error message, if the file was not found in the found.
  • The “IOException” catch block is used to throw an error message, if the input/ output operation issues.
