What would you like to see in Java?

Like in topic - what would you see in Java?

My propositions:

1. Operator overloading
This would be VERY useful for vector and matrix math, I think this is obvious.

2. New “for” loop
We use code like this very often:

for (int i = 0; i<20; i++) {
    for (int i2 = 0; i2<20; i2++) {
        doOrGetSomething(i, i2);
    }
}

Why not replace it with something like this:

for (int i -> 0 : 20) {
    for (int i2 -> 0 : 20) {
        doOrGetSomething(i, i2);
    }
}

or this:

for (int i, i2 -> 0 : 20) {
    doOrGetSomething(i, i2);
}

or even this (only for arrays and collections) - I know we have “for each” loop, but it cannot be used in some cases:

for (int i, i2 -> array2d) {
    doOrGetSomething(array2d[i][i2]);
}

for (int i -> list) {
    doOrGetSomething(list.get(i));
}

Both of this ideas are just syntatic sugar, but in my opinion would be useful. :slight_smile:
