`parseCoin()` now accepts negative values; the check for an excessive value is moved to the constructor from `parseCoin()` and uses `checkArgument()`; some `Coin`-type constants broken out into one `long` one `Coin` in order to be usable in the constructor. Corresponding tests included. The `BitcoinURI` class constructor throws exception on parsing a negative amount, which is needed now that `Coin` class accepts negative amounts.
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://bitcoinj.github.io/getting-started
