What is Runtime

Introduction to Runtime

In computer programming, "runtime" refers to the period during which a program is executing. It contrasts with other phases like compile time or design time.

Significance of Runtime

Runtime is critical as it determines how a program interacts with the system, manages resources, and responds to user inputs during execution.

Types of Runtime Environments

• Standalone Runtime: Programs run independently on a specific system.
• Web Runtime: Applications execute within a web browser environment.
• Virtual Runtime: Programs run in virtualized environments like the Java Virtual Machine (JVM).

Runtime Errors

Errors occurring during runtime can disrupt program execution. Common examples include:

• Null pointer exceptions
• Division by zero
• Memory leaks

Importance of Understanding Runtime

A solid grasp of runtime concepts helps developers optimize application performance, debug errors efficiently, and build reliable software.
