So the order is stored in 0x0002, 0x0003, 0x0004, 0x0005 four consecutive bytes, in accordance with 0x0002%2=0. The third variable, C, has its own alignment value of 2, so the valid alignment value is 2, which is stored sequentiallyIn 0x0006, 0x0007, in accordance with 0x0006%2=0.

general compilation and runtime, and they are available only during the test compilation and test run phases.V. System: Scope of systemsSystem-wide dependencies are similar to provided, but you must explicitly provide a path to the jar file in the local system. This is done to allow compilation based on local objects, which are part of the System class library. Such artifacts should always be available, and Maven will not look for it in the warehouse. If you set a dependency scope to a system s

sentence compilation does not pass Final New StringBuffer ("111"); a.append ("222"); // compiled byAs you can see, final is valid only for the reference "value" (that is, the memory address), which forces the reference to point only to the object that was initially pointed to, and changes its point to cause a compile-time error. Final is not responsible for the change in the object it points to.Summarize　　A reference to the local variable data and objects (String, array, object, and so on) that
