Get the JDK & Bluej from net and the rest will be done by them.
Java byte codes are stored as *.class ; where "*" represents the class name, in your hard disk.
You can download BlueJ as well as JDK from the related link.

Executon steps in java?
First of all the compiler converts our source code into byte code ,this is done by "javac" compiler.then we use interpretor that is the"java interpretor" for making our byte code executed.thats y java is called as an compiled and interpred language.by that way our java program will be interpreted. First of all our source code vl b converted into byte code by da java compiler named "javac" ,then dt byte code vl be executed by da interpretor named "java" interpretor. These are execution steps in java dts y v call java as a compiled and interpreted language.
What is bytecode and java virtual machine in java?
A traditional compiler compiles the source code to machine language. Java compiles for a "ficticious CPU", not for a specific CPU (processor). The compiled code is called "bytecode" (technically, any information stored on a computer is made up of bytes!). To run the program, this bytecode is interpreted by the Java Virtual Machine.
What do you call java and javascript?
Well you get java as java and javascript as iava.
Difference between program counter and instruction pointer?
There isn't any difference. Two different words forexactly same thing. Third way to call it is instruction address register.
Difference between portability and platform independent?
Platform independence refers to the fact that java compiled code (byte code) can execute on any operating system. A programme is written in a language that can be understood by humans. It could contain words, phrases, or other information that the system doesn't understand.... The Java Byte Code is the intermediate representation in Java.

Mention any one byte call instruction and the address to which it is points to?
RST 2 is one example of a one byte call instruction. It points to 0010H.
Justify RST instruction can be called 1 byte Call instruction?
The RST instruction is a 1 byte opcode with a 3 bit imbedded operand. There are 8 different RST instructions. Each pushes the PC on the stack, and loads the PC with the operand's value times 8. (0H, 8H, 10H, 18H, etc.)Pushing the PC on the stack and loading a new value into the PC is exactly what a CALL instruction does, so the RST instruction is a 1 byte CALL instruction. The difference between RST and CALL is that CALL is a 3 byte instruction which can go anywhere in memory in one instruction.

Why call instruction in 8085 microprocessor have 18 state and how its operate?
The CALL InstructionOpcode OperandCALL 16-bit memory addressof a subroutineIt is a 3-byte instruction that transfers the program sequence to a subroutineSaves the content of the PC (Program Counter-16-bit register) , the address of the next instruction , on the stackDecrements the stack pointer register by 2Jumps unconditionally to the memory location specified by the 2nd and 3rd bytes.This instruction is accompanied by a RETURN instruction in the subroutine
What will be the content of program counter of 8085 mpu has fetched machine code located at the memory location 205FH?
It depends on whether the machine code is one, two, or three bytes long, and on whether or not the instruction transferred control to another location. In the case of a non-jump single byte instruction, the PC will have a value of 2060H after the instruction is complete, and it will be 2061H or 2062H after a two or three byte instruction. In the case of a jump, call, or interrupt, the PC will depend on the instruction.
How 8085 responds to intr interrupt?
when this interrupt occurs, the processor fetches the bus one instruction usually one of these instructions as given, one of the 8 RST instructions( RST0 - RST7), the processor saves the current program counter into the stack and the branches from N*8 (where N is 3 bit number from 0 to 7). call instruction which is a 3 byte inst. the first byte is the address branch which chosen based on the second and the third byte of the instruction set.

What is subroutine in 8085?
in 8085 microprocessor a subroutine is a separate program written aside from main program ,this program is basically the program which requires to be executed several times in the main program. the microprocessor can call subroutine any time using CALL instruction . after the subroutine is executed the subbroutine hands over the program to main program using RET instruction.
What is a trap instruction?
A trap instruction is a software interrupt. It's generated by an error or by a user program when it needs the operating system to perform an operation (a system call).
What do you call 1 part of a byte?
1 byte = 8 bits
Does java support call by reference?
No , Java does not support call by reference.
What is instruction prefetching?
Instruction pre-fetching is very important phenomena in 8086 microprocessor. There is a 16-bit register set located in the BIU (bus Interface Unit) known as QUEUE.While EU (Execution Unit) is working on the instructions i.e decoding and executing them, queue fetches the next sixinstruction byte of the running program. It is to be noted that, unlike stack (which is last in first out), queue is first in first out. Instruction which is fetched first is retrieved first.This is much faster than sending out the address and waiting for memory to send back the instruction byte or bytes.Limitation of QUEUE:This pre-fetching of instruction speeds up processing but sometimes during 1JMP and CALL statements, queue has to be dumped and reloaded again starting from the next address.Fetching the instruction while the current instruction executes is called pipelining.1. Like in c++ programming, when a function is called the control is transferred to the function and its instruction
