Compiling a Java program means taking the programmer-readable text in your program file (also called source code) and converting it to bytecodes, which are platform-independent instructions for the Java VM.
What is meant by compilation in programming?
Compiling is the transformation from Source Code (human readable) into machine code (computer executable). … A compiler takes the recipe (code) for a new program (written in a high level language) and transforms this Code into a new language (Machine Language) that can be understood by the computer itself.
What do you mean by Java compilation process explain with the help of diagram?
Answer. In Java compilation process, the source code of a Java program is compiled to an intermediate binary code called the Bytecode. This Bytecode cannot be directly executed by the machine. It is understood by a virtual machine known as Java Virtual Machine or JVM.
What are the steps in Java compilation process?

- Step 3: Create the . …
- Step 4: Write the Native Method Implementation. …
- Step 5: Create a Shared Library. …
- Step 6: Run the Program.
What is the purpose of compiler in Java?
The compiler translates your source code instructions into Java bytecode instructions. In other words, the compiler takes code that you can write and understand and translates it into code that a computer can execute (like the code here).
What is an example of compilation?
The definition of a compilation is a collection of different things, or the act of gathering and putting together things. When you gather together recordings of all of your favorite songs so you can make a mixed tape, this is an example of a compilation.
Why Java uses compiler and interpreter both?
Java Virtual Machine (JVM) takes this Bytecode as input and converts it into Machine Code line by line. So, JVM acts as an interpreter for converting Bytecode to Machine Code. In this way, a Java program uses both a Compiler as well as an Interpreter to get executed on the processor.
What are the 2 steps in Java compilation?
Compile and Run Java Program: It’s Two Step Process
Compilation and execution of a Java program is two step process. During compilation phase Java compiler compiles the source code and generates bytecode.
How is Java compilation different from ordinary compilation?
What is the difference between ordinary compilation and Java compilation ? Ans . In ordinary compilation the source code is directly converted into machine or object code using an interpreter or a compiler . In Java compilation into an the source code is first converted into an intermediate code called the byte code.
What is interpreter in Java?
Interpreter in Java is a computer program that converts high-level program statement into Assembly Level Language. It is designed to read the input source program and then translate the source program instruction by instruction.
What is Java life cycle?
Life Cycle of Thread in Java is basically state transitions of a thread that starts from its birth and ends on its death.
What are the features of Java?

What do you mean by abstraction in Java?
In Java, Data Abstraction is defined as the process of reducing the object to its essence so that only the necessary characteristics are exposed to the users. Abstraction defines an object in terms of its properties (attributes), behavior (methods), and interfaces (means of communicating with other objects).
What is the Java compiler called?
In fact, the Java compiler is often called the JVM compiler (for Java Virtual Machine). Consequently, you can write a Java program (on any platform) and use the JVM compiler (called javac) to generate a bytecode file (bytecode files use the extension .
What is name of Java compiler?
javac – Java programming language compiler.
What language is Java compiler?
The Java compiler is written as a Java program and then compiled with the Java compiler written in C(the first Java compiler). Thus we can use the newly compiled Java compiler(written in Java) to compile Java programs.
