assigned with the New keyword.3.stack space is limited, and the heap space is a large free zone.In Java,If you just declare an object, assign it to the address space in the stack memory first.If you instantiate it again, it will be assigned an address in heap memory.4. For example:Data type variable name; This defines something in the stack area.such as: Object a =null; Allocate space only in stack memoryNew data type (), or malloc (length); That's w

1. Java and his APIs can use concurrency. You can specify that the program contains different execution threads, each with its own method call stack and program counter, allowing threads to concurrently execute resources, such as shared memory, that can share the program's scope with other threads, known as multithreaded Programming (multithreading), at the core of C and C This ability is not available in the + + language, although they affect the des
