JRE comprises of ___________ and ___________.Select one or more:a.APIb.JVMc.JDKd.tools

Break Down the Problem

1. Identify what JRE (Java Runtime Environment) includes.
2. Review the options provided to determine which are relevant components of JRE.

Relevant Concepts

• JRE is a part of the Java environment that allows Java programs to run. It mainly consists of two core components:
  • JVM (Java Virtual Machine): This is the part of the JRE that executes Java bytecode.
  • Libraries: These provide the necessary APIs to run Java applications.

Analysis and Detail

• JVM: This is essential as it enables the execution of Java applications and provides a runtime environment.
• API: While JRE allows the use of APIs, they are typically part of the broader Java Standard Library, not a component of JRE itself.
• JDK (Java Development Kit): This is not part of JRE but a separate package that includes everything needed to develop Java applications.
• Tools: While there are tools that come with JDK for development, they are not components of the JRE.

Verify and Summarize

• Based on the analysis above, the only significant component of JRE from the options provided is the JVM.

Final Answer

The correct selections are:

• b. JVM
