This source code explain on how to make selection using If in Java. This Source code show the program using BufferedReader that means a user save the data which inputted by user. Remember in Java there is no 'reserved word' looks like cin>> or scanf(" ") in C++ and C. The Statement of IOException explain us to handle if there is any errors, and The 'InputStreamReader' explain to input what the 'user defined ' for data that inputted.
