Q:

What is Interpreter in Java?

Answer

  • An Interpreter is a program that reads in as input a source program, along with data for the program, and translates the source program step by step.


 


The Java interpreter decodes each lines bytecode and runs a series of machine instructions for that bytecode. The JVM takes the byte code and generates machine code. The byte code is compiled to machine code, and the machine code is executed.

The usual cause of sea breeze is the difference in specific heat capacity between land and water Land heats and cools more quickly than water.

 

What is the cause of a sea breeze?

The air over the land is warmed and rises, to a greater temperature than that over the sea. This produces a convection current, with cooler air flowing in from over the sea to replace that rising from the land. At night the land cools more than the sea, so the action reverses to produce a land-breeze, blowing off the land.
