Compiler translates entire code to machine language, while interpreter translates line by line.
Compiler generates object code, while interpreter executes code directly.
Compiler is faster, but interpreter is more flexible.
Examples of compilers: GCC, Clang. Examples of interpreters: Python, Ruby.
Compilers are used for languages like C, C++, while interpreters are used for languages like Python, Ruby, JavaScript.
A thread is a lightweight process that can run concurrently with other threads within a program.
Threads share the same memory space as the parent process.
Threads can communicate with each other through shared memory.
Threads can improve performance by allowing multiple tasks to be executed simultaneously.
Examples of multi-threaded programs include web servers and video games.
The main function of exception is to handle errors and unexpected events in a program.
Exceptions allow for graceful handling of errors and prevent program crashes.
They provide a way to transfer control from one part of the program to another.
Exceptions can be caught and handled in a try-catch block.
Examples of exceptions include divide-by-zero, null pointer, and file not found errors.
JVM stands for Java Virtual Machine. It is an abstract machine that enables a computer to run Java programs.
JVM is responsible for interpreting Java bytecode and executing it on the computer.
