10 Useful NetBeans IDE Java Shortcuts

1. Type "fcom" (without the quotes, same as all the rest below) and then press Tab. You now have this, i.e., a brand new code fold:

// 
// 

2. Type "bcom" and then press Tab to create the start of a new set of comments in your code:

/**/

3. Type "runn" and press Tab and you'll have all of this:

Runnable runnable = new Runnable() {

    public void run() {

    }
};

4. If I have this:

String something = "";

...and then below that type "forst" and press Tab, I now have this:

String something = "";
for (StringTokenizer stringTokenizer = new StringTokenizer(something); stringTokenizer.hasMoreTokens();) {
    String token = stringTokenizer.nextToken();

}

Also, experiment with "forc", "fore", "fori", "forl", and "forv"!
5. I always knew that "sout" turns into "System.out.println("");" but did you know that (again assuming you first have a string something like above) if you type "soutv" you end up with this:

System.out.println("something = " + something);

Thanks Tom Wheeler for this tip.
6. Next, here are the new shortcuts that are new from NetBeans IDE 6.9 onwards:
as - assert=true;
su - super
db - double
sh - short
na - native
tr - transient
vo - volatile

7. I knew that "ifelse" would resolve to an if/else block. But did you know that if you don't need an 'else', you can simply type "iff", press Tab, and then end up with this:

if (exp) {

}

8. From NetBeans IDE 6.9 onwards, the "sw" shortcut expands to the following:

switch (var) {
    case val:

        break;
    default:
        throw new AssertionError();
}

9. If you're using while loops, experiment with "whileit", "whilen", and "whilexp".
10. Always remember these: "im" expands to "implements; "ex" to "extends".
