allocate array during run-time

I'm trying to allocate an IntBuffer during run-time once I know the
size I need but I can't get the following to compile. Eclipse
highlights the reason as such ...

[code]
Syntax error on token "]", VariableDeclaratorId expected after this
token.
[/code]

[code]
    private IntBuffer[] indBuffers;

    public void myMethod(int val) {
        indBuffers[] = BufferUtils.newIntBuffer[val];
// error in above line
...
[/code]

Leave out the [] - the name of the variable is just indBuffers.

Assuming BufferUtils.newIntBuffer is an IntBuffer[][], then you would write
something like:

<code>
indBuffers = BufferUtils.newIntBuffer[val];
</code>

but if BufferUtils.newIntBuffer is actually a method which takes a single
integer as an argument and returns IntBuffer[], then you would write
something like:

<code>
indBuffers = BufferUtils.newIntBuffer(val);
</code>
