Java divides memory into two types: one is stack memory and the other is heap memory. Some basic types of variables and object reference variables defined in the function are allocated in the stack memory of the function, and when a variable is defined in a block of code,

to call the function to free memory, but it can only reclaim the useless and no longer referenced by other objects of the space occupied by those objects.The memory garbage collection mechanism of Java is to check the reference chain from the main running object of the program, and when it is traversed, it is found th

in the Java heap is absolutely regular, that the used and idle memory is on one side, that a pointer is placed in the middle of the point indicator, and that the allocation of memory is to move that pointer over the free space to a distance equal to the object's size.

memory for the new object. The task of allocating space to an object is equivalent to dividing a certain size of memory from the Java heap. There are two ways of allocating: A pointer collision, which assumes that the memory in the Java heap is absolutely regular, that the

Java divides memory into two types: one is stack memory and the other is heap memory. Some basic types of variables and object reference variables defined in the function are allocated in the stack memory of the function, and when a variable is defined in a block of code,

must first perform the appropriate class loading process.After the class load check passes, the virtual machine allocates memory for the new object. The size of the memory required by an object is fully determined after the class is loaded, and the task of allocating space to an object is equivalent to dividing a size of memory from the

Local method Stack (thread private)　　　　The local method stack is very similar to the virtual machine stack (Native), except that the virtual machine stack serves the Java method (bytecode) and the local method stack serves the Native method used by the virtual machine.

Introduction of the problem: Question one: String str1 = "abc";String str2 = "abc";System.out.println (STR1==STR2); True Question two: String str1 =new string ("abc");String str2 =new string ("abc");System.out.println (STR1==STR2); False Question three: String S1 = "Ja";String s2 = "va";String s3 = "Java";String S4 = s1 + s2;System.out.println (s3 = = S4);//falseSystem.out.println (S3.equals (S4));//true Because the above problem makes me ambiguous, s
