Which of the following is not one of the three layers used by the Java interpreter?

A. Java language

B. Java script

C. Java libraries

D. Java interpreter

Solution

B. The Java script is used by the Java interpreter and is not one of the three layers. Answers A, C, and D do not successfully answer the question, but they do make up the three layers used by the Java interpreter. These include the Java language, which interprets code downloaded from a website; Java libraries, which prevent undesired access to resources and help implement a security policy; and the Java interpreter, which converts the code into native machine code.
