Java is both compiled and interpreted.
At first, the Java source code (in .java files) is compiled into the so-called Bytecode (.class files). The Bytecode is a pre-compiled, platform independent version of your program. The .class files can be used on any operating system.
When the Java application is started, the Bytecode is interpreted by the Java Virtual Mashine. Because the Bytecode is pre-compiled, Java does not have the disadvantages of classical interpreted languages, like BASIC.

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.
Why java is platform independent explain by diagram?
Java is a platform independent language becoz of the bytecode magic of java. In java, when we execute the source code...it generates the .class file comprising the bytecodes. Bytecodes are easily interpreted by JVM which is available with every type of OS we install.
Is java interpreter or compiler?
Java has both a compiled and an interpreted stage.1) The programmer writes his source codes (.java extension); a compiler will compile this to bytecode (.class extension).2) When the end-user runs the .class program, the JVM (Java Virtual Machine) will interpret this.
What are the different phases of java?
Based on the lecture i have , there are three JAVA PHASES -- editor. First step in creating java program is by writing ur programms in a text editor. Ex, notepad, emacs etc -- java compiler. compile. The program by. Using the java compiler. The output of this process is a file of java bytecodes wid the file extension.class -- java interpreter. The .class file is then interpreted by java interpreter that converts the bytecodes into the machine language of the particular computer your using ---abioo4---
Why java applet is executed faster than java script?
The java applet is in the java language and is run local to your computer, java script is in the language java script, this can be run local to server or computer. Java and java script are to different languages that run two different ways.
Can vista read java?
Yes. Due to Java being an interpreted language, almost any system can read it. In fact, I'm running vista with java right now.

WHO convert high level program in to machine language programs?
Nobody. Conversion from high-level encoding to low-level encoding is achieved via software, either by a compiler (compiled languages) or by an interpreter (interpreted languages). Some languages, such as Java, use both; compiling to Java byte code which is then interpreted by the Java virtual machine.
What in computing is java?
Java is a computer programming language. Java programs can be interpreted (the computer compiles and runs the program as the code is executed) or it can be pre-compiled into bytecode (the computer doesn't have to compile it as soon as it is run, so time is saved.)

Why 2 files in java program?
There are programming languages in which the source file is read and interpreted directly, but those are usually slower than when the program is compiled, to an EXE, or as in Java, for a virtual machine.
Where is a program temporally stored for execution?
All programs must be loaded into memory (e.g., RAM) in order to be executed. Compiled programs can be loaded directly since they consist of native machine instructions, but interpreted programs must be translated by a runtime program. E.g., Java is an interpreted language which compiles to byte code which must be interpreted by the Java Virtual Machine implementation at runtime.
Advantages of C over C plus plus and java?
C can be faster than C++ programs, and definitely faster than Java, since Java is primarily interpreted. C is also somewhat less rigid in definitions as well, not as tightly structured as either C++ or Java can be.
What are the major differences between Java programming language and any other programming language?
Java, while not very different from some languages is different from most languages is that it is interpreted, it is not in a language that the computer can understand, it is run by the jvm. Unlike interpreted languages, however, it also has a compiler which compiles to java bytecode. This is not a real compiler, however, as it's output must still be interpreted. Indeed, the output is even possible to be "decompiled" and turned back into source, only loosing some nonessential things like comments.
Is groovy an interpreted language?
Yes, Groovy is primarily an interpreted language. It is often run on the Java Virtual Machine (JVM) and is compiled to bytecode at runtime. This makes Groovy a dynamic language with scripting capabilities.
What is buzz word in java define?

Why it is not possible to execute java program on machine which does not have JVM installed on it?
when a java program is compiled it is converted into a non executable code which is byte code, and this byte code can only be interpreted by JVM. so a java program can't be executed on a machine which doesn't have JVM installed on it.
Why java applet is executed faster than java script?
The java applet is in the java language and is run local to your computer, java script is in the language java script, this can be run local to server or computer. Java and java script are to different languages that run two different ways.
Differencitate between source code and bytcode in java?
The source code is just the set of statements written in (any included) java language by a programer (in this case our source code is a text file with .java extension). And in other hand a bytecode is the resulting code of compile a .java file, It is not machine code, but it can be interpreted and executed by the jvm.
Is a c plus good or bad?
Basically both are good at their places, can't be interchanged. But Java is best if we compare both because Java is much more secure, robust and portable as compared to C++ as a Java program is first converted to byte code and then interpreted. Also C++ program is compiled all at once but Java program is interpreted one instruction at a time thus making it more secure .
Why net is need when have java?
Java (from Sun) is a programming language that is interpreted in bytecode using a virtual interface, it sounds complicated and it is more complicated than simply using HTML to display a page, and it is also much slower.
Java is both compiled and interpreted language meaning?
Instead of compiling to machine language, the Java compiler compiles for a "ficticious processor". A program called the Java Virtual Machine then interprets this on every machine. To learn this java course techpragna is the best institute in bangalore
Is Java or C plus plus faster?
Java is considerably more convenient than either C or C++ due to its extremely high level of abstraction. However, that convenience comes at the cost of both performance and efficiency.
