protected, default (package) access, and private fields, but excludes inherited fields. The elements in the array returned are not sorted and are not in any particular order. This method returns an array of length 0 if the class
For example, when we compare int primitive (which consumes only 4 bytes) to the Integer object which takes 16 bytes, we see that there is 300% memory overhead. 3. Estimating Object Size Using Instrumentation One way to get an estimate of an object’s size in Java is to use getObject...

Here are some strategies for optimizing memory usage in Java applications: Use primitive types instead of wrapper classes when possible. Wrapper classes, such asIntegerandBoolean, have a larger memory footprint compared to their primitive counterparts. ...
