Possible Duplicate:
Setting JVM heap size at runtime

Is it possible to prevent a program from crashing when it encounters a OutOfMemoryError by increasing the memory allowed to the program?
Can it be done at run time?

Reason for increasing the memory

I was talking a lot of screen shots using java.awt.Robot and after some time my Vector ran out of memory. At 60 BufferedImage it was out.
so 1280 x 800 resolution, 3 byte RGB BufferedImage and 60 images later, the vector was out.
So I guess the memory consumed was
1280 x 800 x 60 x 3 = do the math bytes

    You may need to think of other solutions other than dynamically changing memory size including

    • allocating a reasonable amount of memory to start with.
    • decreasing the resolution of your captured images (which is what I did for a similar problem by decreasing image size)
    • caching your images to disk when not immediately needed vs. a combination.
