* added null handling so equals methods return false for null argument * replaced instanceof with getClass to force strict type equality * added @Override for equals and hashCode where missing * minor refactorings in equals methods to simplify and improve consistency * added missing hashCode for ListMessage based on equals definition Things that HAVE NOT changed: * set of attributes used for equality checking * hashCode calculation (except for added hashCode in ListMessage) * correlation between equals and hashCode * no new equals methods added
To get started, ensure you have the latest JDK installed, and download Maven from: http://maven.apache.org/ Then run "mvn clean package" to compile the software. You can also run "mvn site:site" to generate a website with useful information like JavaDocs. The outputs are under the target/ directory. Alternatively, just import the project using your IDE. IntelliJ has Maven integration once you tell it where to find your unzipped Maven install directory. Now try running one of the example apps: cd examples mvn exec:java -Dexec.mainClass=com.google.bitcoin.examples.ForwardingService -Dexec.args="<insert a bitcoin address here>" It will download the block chain and eventually print a Bitcoin address. If you send coins to it, it will forward them on to the address you specified. Note that this example app does not use checkpointing, so the initial chain sync will be pretty slow. You can make an app that starts up and does the initial sync much faster by including a checkpoints file; see the documentation for more info on this. Now you are ready to follow the tutorial: https://code.google.com/p/bitcoinj/wiki/GettingStarted
