memory. As soon as the maximum heap memory set by-XMX is reached, if no more memory can be allocated to the new object, the JVM throws java.lang.OutOfMemoryError, and your program is dropped. Before throwing the OutOfMemoryError, the JVM tries to use the garbage collector to free up enough space, but when it finds that there is still not enough space, it throws the error. To solve this problem, you need to know the information about your program object, for example, what objects you create, wha

can use the command "Jmap" to obtain heap dump, with "jhat" to analyze heap dump. 7, Java heap space is different from stack space, stack space is used to store call stacks and local variables. 8. The Java garbage collector is used to reclaim memory from dead objects (objects that are no longer used) and then to release them into the Java heap space. 9, when

Java runtime memory Zone When running a Java program, the Java Virtual Machine divides the memory areas it manages into multiple different areas. Each region has its own purpose, Creation Time, and destruction time. Some exist with the startup of virtual machines, and some rely on user threads to start and destroy them. HandleThe

They are all through monitoring the application, release, and other actions of all objects when Java programs are running, collects, analyzes, and visualizes all memory management information. Based on this information, developers will determine whether the program has a memory leakage problem. These tools include optimizeit profiler, Jprobe
