Java vs python

java --

• write one and run everywhere as it gets compiles

python

• temp

Hello world

public class HelloWorld {
    public static void main(String args){
        System.out.print("Hello World");
    }
}

• java needs more elaborate structure for the same output

• psvmsa -— public static void main string args [program entry point)

  • This method clearly indicates where the program's execution commences, and any command-line arguments are directly accessible through the args String array.

• By requiring all executable code to be part of a class and explicitly invoked, Java mitigates risks associated with unintended side effects or the execution of potentially malicious code during module imports.

• python has

if __name__ == "__main__":

• this indicates that the code should only execute when the script is run directly rather than when it is imported as a module.

• command line args are accessed via sys.args
