Java

What is Java?

Java is an object-oriented programming language, which means everything should be an object.

Is Java Compiled or Interpreted?

Java is both compiled and interpreted. It is first compiled into bytecode by the Java compiler (javac), then the JVM (Java Virtual Machine) interprets or JIT-compiles this bytecode to machine code at runtime.

Is Java Strongly Typed or Loosely Typed?

Java is a strongly typed language. Variables must be explicitly declared with types, and type mismatches are caught at compile time, ensuring type safety.

Is the Java platform independent or dependent?

Java is platform-independent at the bytecode level. Java code is compiled into bytecode, which can run on any platform with a Java Virtual Machine (JVM). This "write once, run anywhere" capability makes Java platform-independent. However, the JVM is platform-dependent and specific to the operating system and architecture.

IDE - It is used to write, compile and debug the code.
JDK - JDK is also known as Java Development Kit; it compiles Java code.
JRE - JRE stands for Java Runtime Environment. It's a software layer that sits on top of your operating system and provides the necessary environment for running Java programs.
JVM - JVM, or Java Virtual Machine, converts bytecode to machine-specific code.
