Types of references

Understanding soft references in Java

Report a typo

Hey there! This problem might be a bit unpredictable, but give it a go and let us know how you do!

Consider the following code snippet in Java.

String str = new String("Hello");
SoftReference softStr = new SoftReference(str);
str = null;
System.gc();
str = softStr.get();

What type of references is used, and when is the garbage collector likely to reclaim the memory allocated for the str object?

Select one option from the list

A Weak reference is used, and the garbage collector is likely to reclaim the memory during the next garbage collection cycle.

A Soft reference is used, and the garbage collector is likely to reclaim the memory when the JVM runs out of memory.

A Phantom reference is used, and the garbage collector is likely to reclaim the memory after the finalize() method is called and it ensures that it is no longer reachable.

A Strong reference is used, and the garbage collector is likely to reclaim the memory when the JVM runs out of memory.
