Application use java. When run script, it returns

./browser.sh
./browser.sh: 7: ./browser.sh: java: not found

I check java version:

```
java -v
The program 'java' can be found in the following packages:
 * default-jre
 * gcj-4.8-jre-headless
 * openjdk-7-jre-headless
 * gcj-4.6-jre-headless
 * openjdk-6-jre-headless
Try: sudo apt-get install <selected package>

```

Which package should I install?
