Java combines the two strategies of compilation and interpretation as depicted in Figure3 Source code is compiled to JVM bytecode This bytecode can immediately be interpreted by the JVM interpreter The interpreter also monitors how much each piece of bytecode is executed (run-time pro?ling)
A Java Development Kit (JDK) is a software package that contains not only a JRE but a Java compiler so that Java programs can be compiled/translated into Java bytecode There are several versions of the JDK The major one can be found here (as of 2018 January): http://www oracle com/technetwork/java/javase/downloads/index html

An interpreter is simpler than a compiler It includes the parser but instead of the code generator the interpreter goes through the internal representation of the source code (such as an abstract syntax tree) and ‘executes’ the code directly

–The interpreter and JIT compiler work together –The interpreter is instrumented to count method calls –When the interpreter discovers that a method is “hot” (called frequently) it tells the JIT compiler to translate that particular method into native code Selective Java JIT compilers are integrated into web browsers
Why does Java need both compiler and interpreter?
The Java source code first compiled into a binary byte code using Java compiler, then this byte code runs on the JVM (Java Virtual Machine), which is a software based interpreter. So Java is considered as both interpreted and compiled. The compiled byte code allows JVM to be small and efficient, and fast performing.
Is compiler better than interpreter and why?
A compiler is comparatively faster than Interpreter as the compiler take the whole program at one go whereas interpreters compile each line of code after the other. The compiler requires more memory than interpreter because of the generation of object code. Herein, which is better interpreter or compiler?
How does Java use both compilers and interpreters?
you write your code and save it as a .java file. The compiler takes your .java file and compiles it into a .class file (the .class file contains Java byte code). The interpreter comes in when your program is run. The JVM (or interpreter) takes your .class file and interprets it.
