Hello, Currently i am using the Java 5.0 and I am using the Scanner Class for input. I was just wondering if there is a faster input and also output that will speed up compiling times and if, can you show or provide a tutorial for it. Thanks |

Most Java libraries are fairly optimized. If the Scanner suits your needs, stick with it, because it does a lot of work for you. If you are reading/writing from a file, a BufferedReader/BufferedWriter may be what you're looking for. There are plenty of tutorials available. To improve compile times, avoid including entire packages, e.g. import javax.swing.JFrame; rather than import javax.swing.*; |

To speed up compile times, limit your imports as chrisbrown suggests. To speed up your use of Scanner (assuming you're reading from a file), use a BufferedReader. Example:
