Add useful things to the API to help beginners.

I think Mustang should have something like java.homework, to handle common homework assignments for classes like data structures or simple Java homework.
Examples might be: "java.homework.BankTellerList" or "java.homework.CalculateAverageOfFloats" and stuff like that. That would make homework assignments much easier, and for people who couldn't do the homework, helping them would be easier too: You'd just say "see java.homework.j101.HelloWorld".

These kind of things belong to demos and tutorials, not to platform. This forum is not about demos and tutorials, I believe.

He might have spent too much time on forums.java.sun.com and have meant this seriously .

Add the class: YetAnotherStupidBeginnerError extends Error.
public class MyClass {
public static void main(String args[]) {
try {
for (int j = 0; j <= args.length; j++) {
System.out.println("arg " + j + " = " + args[j]);
}
} catch (YetAnotherStupidBeginnerError e) {
e.printStackTrace();
}
}
}
In this case, the YetAnotherStupidBeginnerError will be thrown when the JVM analyses the code, before it is executed and has a chance to throw an IndexOutOfBoundsException.

Well that would really be a great addition to Java which would finally lead to Java's world success over .NET etc Might even prove the halting problem wrong.

Horrible
I suggest that compiler automatically optimizes such code by fixing accidental '

Good idea, it would also automatically fix stuff like:boolean a = false;
boolean b = true;
if (a = b) {
System.out.println("a and b were equal");
}
orpublic class Light {
private boolean on = false;
public void toggle() {
on = !on;
}
public boolean isOn() {
return !isOff();
}
public boolean isOff() {
return !isOn();
}
}

Great idea. Should be the minimal requirement for JDK 6.0

I'm sorry, but I don't think the compiler playing with operators is a good idea at all. Even more so when it's a newbie programming. You don't learn how to code without making a few mistakes and tracking down a few bugs. I would lose my mind if I wanted something like if(a=b), the compiler decided that wasn't a good idea, and I had to find out what the compiler flag was to make the code compile as I had written.

Uhh ... with tools like the Inspection Gadgets plugin to IDEA, these kind of newbie errors could easily be pointed out. Or with PMD integrated, you could get compile-time warnings of newbie errors.

I totaly agree with smbell, the compiler shouldn't be a teacher.
Beginners should read books/articles and write code to learn
how to write code.

ROFL
All these suggestions were just jokes!
Anyway, do you know about plans to support JDK 5.0 syntax
by tools like PMD, checkstyle and so on?
I have just switched to JDK 5.0 and miss these tools a lot.
