Put a password or licence check at start of application. With proper authentication, only user must be able to run the application further.

For password check, you should generate private-public key concepts. For licence, some installed software or attached hardware can be use to provide access.

As Jigar Joshi said you can obfuscate your jar file. Proguard is a good one. Here's the link to it. http://java-source.net/open-source/obfuscators. Alternately you can convert jar to exe using jar to exe converter. You can download it here. But you have to purchase it. http://www.regexlab.com/en/jar2exe/.

You can't 100% stop decompilation but you can obfuscate your code that will be hard to read once after decompilation
