PPT-1 Chapter 12 Exceptions and File Input/Output

CS1 Java Programming Colorado State University Original slides by Daniel Liang Modified slides by Chris Wilcox 2 Motivations When a program runs into a runtime error the program terminates abnormally How can you handle the runtime error so that the program can continue to run or terminate gracefully This is the subject we will introduce in this chapter.

WIPO Advanced Research Forum. Geneva, 28-30 May 2012. Debates on the . drafting of exceptions. These debates are often framed around the respective merits of open-ended general provisions (. Types of exceptions. Checked exceptions:.  A checked exception is an exception that is typically a user error or a problem that cannot be foreseen by the programmer. For example, if a file is to be opened, but the file cannot be found, an exception occurs. These exceptions cannot simply be ignored at the time of compilation. Chapter 11. Reading and Writing .

Chapter 11. Reading and Writing . Textfiles. Data is often stored in files such as a text file. We need to read that data into our program. Simplest mechanism. Scanner class. First construct a FileReader object with the name of the input file.. (Three unrelated concepts). Why use generics?. When you write a collection (something to store data, such as a linked list, . arraylist. , table, . etc. ), you want it to be usable with all kinds of data. You want it to be usable to store Strings, or usable to store integers.. streams. A simple input stream accepts typed data from a keyboard. A simple output stream writes data to the terminal. Standard Input/Output Streams. A . stream. is a sequence of characters. Streams . Difference between PNP and NPN sensors. PNP.  sensors are sometimes called “. sourcing.  sensors” because they source positive power to the output. ..  . NPN. sensors are sometime called “.
