The correctness proof of the statement: Let us create a program in our local IDE and compile it with the help of the Javac compiler. The Java interpreter (JVM) knows where the class files for the standard system classes are located and can load them as needed.
#Convert source file to class files java compiler online code
class file contains Java byte code and is later executed by the JVM(Java Virtual Machine). class files: class_name.class: class_name is name of the class that is present in the Java source file. class files as there are classes declared in the Java source file. class files generated is equal to the number of classes declared in the Java program.Įxplanation: While compiling a program, the javac compiler generates as many. As the Java compiler compiles the source code into the Java bytecode. The JVM uses the interpreter at runtime, after that it execute the code on the host machine. The JVM converts that code into machine code using the Java interpreter. class file on the Java Virtual Machine (JVM). This time program compiles successfully without any errors.ģ. To convert the byte code into machine code, we deploy the.
Now we will check whether our program compiles successfully or not if we declare one of the classes as public.įor example, In the below program, we have created three empty classes (Geeks, Learning, and Programming), and exactly one of them is a public class(Geeks). The correctness proof of the statement: In statement 1 (please refer to fig 2), we have already seen that the Java source file name can be anything if none of the classes is declared public. But if there is a class that is declared as public, the name of the Java source file must be the same as the public class name. The name of the Java source file can be anything provided that no class is declared as public.Įxplanation: Java allows us to name the Java source file with anything if there is not a single class that is declared as public. The program compiles successfully without any errors, and corresponding.
