how to print address of a n objectin java code example
Example: how to get address of object in java
public static void printAddresses(String label, Object... objects) {
System.out.print(label + ": 0x");
long last = 0;
int offset = unsafe.arrayBaseOffset(objects.getClass());
int scale = unsafe.arrayIndexScale(objects.getClass());
switch (scale) {
case 4:
long factor = is64bit ? 8 : 1;
final long i1 = (unsafe.getInt(objects, offset) & 0xFFFFFFFFL) * factor;
System.out.print(Long.toHexString(i1));
last = i1;
for (int i = 1; i < objects.length; i++) {
final long i2 = (unsafe.getInt(objects, offset + i * 4) & 0xFFFFFFFFL) * factor;
if (i2 > last)
System.out.print(", +" + Long.toHexString(i2 - last));
else
System.out.print(", -" + Long.toHexString( last - i2));
last = i2;
}
break;
case 8:
throw new AssertionError("Not supported");
}
System.out.println();
}
