SNAP 7.0 error

when I try to open the image it gives an error every time : Java.lang.OutofMemory error: Java heap space. I am getting this problem on a windows 10 system with 4GB RAM core i3. My zip file has both VH and VV images but it is not opening any of them. Kindly help me with how I can solve this problem.

Unfortunately this error is caused by the low properties of your machine, working in SNAP in general and radar and optical data you need at least, processor i7 and higher, RAM 16 GB , and the storage it depends on your result and products, 500 GB , would be good.
