Must comment on the code at every "/* Comment Here */" section about what the code is doing.

/** * Address.java * * Usage: * java Address

* * For the given page size and virtual address, * this program reports the page number and offset. */

public class Address { public static final int ADDRESS_SIZE = 32;

public static void main(String[] args) { if (args.length != 2) { System.err.println("Usage: java Address

"); System.exit(0); } /* Comment Here */ int pageSize = Integer.parseInt(args[0].trim()); int address = Integer.parseInt(args[1].trim());

int pageBits = 0;

int pageMask = 0; int offsetMask = 0;

/* Comment Here */ switch (pageSize) { case 1024: pageBits = 10; offsetMask = 0x000003ff; pageMask = 0xfffffc00; break; case 2048: pageBits = 11; offsetMask = 0x000007ff; pageMask = 0xfffff800; break; case 4096: pageBits = 12; offsetMask = 0x00000fff; pageMask = 0xfffff000; break; case 8192: pageBits = 13; offsetMask = 0x00001fff; pageMask = 0xffffe000; break; case 16384: pageBits = 14; offsetMask = 0x00003fff; pageMask = 0xffffcfff; break; }

int pageNumber = (address & pageMask) >> pageBits; int offset = (address & offsetMask);

/* Comment Here */ System.out.println("For address " + address + " page number = " + pageNumber + " offset = " + offset);

} }
