Object and reference, Object ReferenceObjects and references Let's look at this example first: Int [] a = {5, 5}; int [] B = a; B [1] = 45; The output value of array a is as follows: 5, 45, 5 This is because a and B point to the same object {5, 5}. both a and B are referred to as references to this object, that is, a and B operate on the same object. Empty object Int [] a = {5, 5}; int [] B = a; a = null; Set a to null, which means that a will

perspective of the leaking memory location: A memory leak in the Java Heap in the JVM, and a native memory memory leak in the JVM's memory. Local and global references JNI exposes instances, array types to opaque references. The native code does not directly examine the context of an opaque reference pointer, but instead accesses the data structure pointed to by an opaque reference by using the JNI funct

This article describes the concepts of strong, soft, weak, and virtual references to objects, their applications, and their representations in UML. 1. Strong, soft, weak, and virtual references to objectsIn previous versions of JDK 1.2, if an object was not referenced by any variable, the program could no longer use the object. That is, only the object is in the accessible (reachable) state before the program can use it. Starting with JDK version 1.2, the re
