Instruction type STAX rp in 8085 Microprocessor
In 8085 Instruction set, STAX is a mnemonic that stands for SToreAccumulator contents in memory pointed by eXtended register denoted as “rp”.Hererp stands for register pair. This instruction uses register indirect addressing for specifying the destination. So using this instruction, the current content of Accumulator will be written to the memory location as pointed by 16-bit address as stored in the register pair. It occupies only 1-Byte in memory. Mnemonics, Operand Opcode(in HEX) Bytes STAX B 02 1 STAX D 12 1 STAX B is an example instruction of this type. It ...
Read MoreInstruction type SHLD a16 in 8085 Microprocessor
In 8085 Instruction set, SHLD is a mnemonic, which stands for Store HLpair using Direct addressing in memory location whose 16-bit address is denoted as a16. As HL pair has to be stored, so it has to be stored in two consecutive locations starting at the address a16. We know that H and L are 8-bit registers. So their contents will be stored in two consecutive memory locations as each memory location can hold 8-bits of data. This instruction uses absolute addressing mode for specifying the destination. It occupies 3-Bytes in the memory. Mnemonics, Operand Opcode(in HEX) Bytes ...
Read MoreUsing activity in SAP for number range intervals and number range objects
As the name indicates, activity 02 is for intervals while activity 17 is for objects. There can be a different number range interval for a given SAP number range interval.
Read MoreHow do Python dictionary hash lookups work?
Dicts are hash tables. No tree searching is used. Looking up a key is a nearly constant time(Amortized constant) operation, regardless of the size of the dict. It creates the hash of the key, then proceeds to find the location associated with the hashed value. If a collision listed address is encountered, it starts the collision resolution algorithm to find the actual value.This causes dictionaries to take up more space as they are sparse.
Read MoreDifference between C++ string constants and character constants
In C++, a character in single quotes is a character literal. It's of type char. For example, 'a' is of type char with a value 97 on an ASCII based system.A character or a string of characters together in double quotes represent a string literal. It's of type const char[] and refers to an array of size length of string + 1. That extra character is there for marking the string's ending.String literals can be arbitrarily long, such as "abcdefg". Character literals almost always contain just a single character. When these are being printed, string literals are printed till the ...
Read MoreCan interfaces have constructors in Java?
No, interfaces can’t have constructors for the following reasons − All the members of an interface are abstract, and since a constructor cannot be abstract. Still, if you try to write a constructor within an interface it will generate a compile time error. Example public interface InterfaceTest { InterfaceTest(){ } public abstract void display(); public abstract void show(); } Error C:\Sample>javac InterfaceTest.java InterfaceTest.java:2: error: expected public InterfaceTest(){ ^ 1 error
Read MoreWhat is the difference between Component class and Container class in Java?
The class Component is the abstract base class for the non-menu user-interface controls of AWT. A component represents an object with graphical representation. The class Container is the superclass for the containers of AWT. The container object can contain other AWT components.
Read MoreIs it possible to exclude subclasses from the results displayed in backoffice in SAP?
You can uncheck the option - Include subtypes in a search bar and this will only give you the results of the parent type.
Read MoreWhat is the Thread class in Java?
The java.lang.Thread class is a thread of execution in a program. The Java Virtual Machine allows an application to have multiple threads of execution running concurrently. Following are the important points about Thread −Every thread has a priority. Threads with higher priority are executed in preference to threads with lower priority.Each thread may or may not also be marked as a daemon.There are two ways to create a new thread of execution.One is to declare a class to be a subclass of Thread.Another way to create a thread is to declare a class that implements the Runnable interface.
Read MoreUsage of subqueries in internal table as condition in SAP ABAP source code.
Note that if you specify an OPTIONS parameter with parenthesis, it will show an error. When you use Where (itab)In this case, itab has only one field with type C and shouldn’t be longer than 72 characters. “Itab” must be specified in parenthesis without any space between parenthesis and table name.You should use the same condition in the internal table as a condition in ABAP source code.
