Strong References: This is the default type/class of Reference Object. Any object which has an active strong reference are not eligible for garbage collection.

2015年9月4日 · A reference is a "pointer" to a memory address in Java, even though Java eleminates direct manipulation of pointers, unlike C++. Objects in Java are never passed to methods or returned by methods, it is always a reference that is being passed.

2024年9月18日 · As a Java developer, knowing how Java handles memory and objects through references is like having a secret map of your application’s brain. In this article, I’ll try to make sense of what Java...

Java Objects are always accessed by a reference. Like the primitive types this reference is passed by value (e.g. copied).

In Java, a reference variable is a variable that holds the memory address of an object rather than the actual object itself. It acts as a reference to the object and allows manipulation of its data and methods. Reference variables are declared with a specific type, which determines the methods and fields that can be accessed through that variable.
