![]() ![]() Cyclic dependencies are not counted as reference so if Object A has reference of object B and object B has reference of Object A and they don’t have any other live reference then both Objects A and B will be eligible for Garbage collection. When an Object becomes Eligible for Garbage Collection in JAVAĪn Object becomes eligible for Garbage collection or GC if its not reachable from any live threads or any static refrences in other words you can say that an object becomes eligible for garbage collection if its all references are null. Below is the architecture to understand the JVM footprint:.J2SE 5(Java 2 Standard Edition) adds a new feature called Ergonomics goal of ergonomics is to provide good performance from the JVM with minimum of command line tuning.If there is no memory space for creating new object in Heap Java Virtual Machine throws OutOfMemoryError or heap space.There are methods like System.gc () and Runtime.gc () which is used to send request of Garbage collection to JVM but it’s not guaranteed that garbage collection will happen.You as Java programmer can not force Garbage collection in Java it will only trigger if JVM thinks it needs a garbage collection based on Java heap size.Before removing an object from memory Garbage collection thread invokes finalize () method of that object and gives an opportunity to perform any sort of cleanup required. ![]()
