Inward Details of Hello Java Program
In the past segment, we have made Java Hello World program and figure out how to assemble and run a Java program. In this segment, we will realize, what occurs while we arrange and run the Java program. Also, we will see a few inquiries dependent on the principal program.
What occurs at compile time?
At aggregate time, the Java record is arranged by Java Compiler (It doesn't collaborate with OS) and converts the Java code into bytecode.
What occurs at runtime?
At runtime, the accompanying advances are performed:
Classloader: It is the subsystem of JVM that is utilized to stack class documents.
Bytecode Verifier: Checks the code pieces for illicit code that can abuse access rights to objects.
Interpreter: Peruse bytecode stream then, at that point execute the directions.
Q) Can you save a Java source document by one more name than the class name?
Indeed, if the class isn't public. It is clarified in the figure given underneath:
To compile:
javac Hard.java
To execute:
java Simple
Q) Can you have different classes in a java source document?
Indeed, similar to the figure given beneath outlines:
