In Java, garbage collector(GC) provides an automatic solution to memory management. Garbage means unreferenced objects and the process of removing the object from a running program is known as garbage collection. In C language, it is the coder’s responsibility to de-allocate memory allocated dynamically using free() function. Same way, In C++ language, it is the coder’s responsibility to de-allocate memory allocated dynamically using destructor. But Java does not support destructor or free() function. In Java it is performed automatically by JVM with the help of Garbage Collector(GC). The Garbage Collector runs repeatedly, checking for objects that are no longer reference and destroyed it. read less
