age = int(input("Enter your age: "))
if age >= 70:
  print ("you may enter")

My advice is to watch some tutorials for a basic understanding and then ask when you get the basics down

This is why people should not start with Python.

 

Python is structurally strict and Java is logically based. If you learned Java before Python you already have the logic down, then if you learned Python first, you will be soo focused on structurally basing everything.

 

This is a mistake @RockSolid1106 and I made when switching our Discord bots to JavaScript from Python. We both hated learning and working with JS

Hopefully this can get you started as it seems the only hurdle you'll have is handling text input. The rest should be pretty straight forward for you. Give it a shot.

Well I do like JS a bit now, seems I understand the basics.

 

@adarw you can use Scanner in Java to take input. Import that by

import java.util.Scanner;

Then create an object of Scanner:

Scanner sc = new Scanner(System.in);

You've now created an object. I'd advise you to understand how objects work if you want to understand what this means. 

 

You can take input in various data types like double, float, int, String:

String s = sc.next(); //You'll only need this and int if you're just understanding the very basics.
int s = sc.nextInt(); //this^^
double n = sc.nextDouble();
float f = sc.nextFloat()

 

A sample program:

import java.util.Scanner;

public class rock {
  public static void main(String args[]){
    Scanner sc = new Scanner(System.in);
    System.out.println("Hey, enter your name!");
    String name = sc.next();
    System.out.println("Enter your age: ");
    int age = sc.nextInt();
    System.out.println("Hey there "+name+", I now know that you're "+age+"!");
  }
}

 

 

Hope this helps.

 

Thankfully the Java shit taught to me at school comes to use.

Python will bitch and yell at you for indentation mistakes

 

Java and a few others don't

no different than forgetting a } somewhere imo.

If it's homework, the point is that you should learn how to do this yourself. We can help you if you try it yourself and can't quite understand something specific or are having trouble debugging your code.

I don't see how this could make you a worse programmer. Poorly indented code is awful and other languages definitely won't yell at you for using proper indentation... as a beginner, one should be more concerned with the logic of what they're typing rather than specific language quirks.

Gotta love it when some IDEs use tab indentation while others use spaces. Heaven forbid you're doing a group project and up with both in the same file.

Hi @adarw, 

Java solution:
 

import java.util.InputMismatchException;
import java.util.Scanner;

public class Application {

    public static void main (String [] args) {
        // Initialize scanner, similar to input in python
        Scanner sc = new Scanner(System.in);

        // Age variable
        int age = -1;

        // Run while loop until we have a valid age
        while (age == -1) {
            try {
                System.out.print("Enter your age: ");
                age = sc.nextInt();
            } catch (InputMismatchException e) {
                System.out.println("That is not a number");
                
                // Clear the previous value
                sc.next();
            }
        }

        if (age >= 70) {
            System.out.println("You may enter");
        } else if (age >= 18) {
            System.out.print("Do you have a VIP pass? (y/n): ");
            String vipPass = sc.next();

            if (vipPass.equalsIgnoreCase("y")) {
                System.out.println("You may enter");
            } else {
                System.out.println("Sorry you must have a pass or be over 70 years old");
            }
        } else {
            System.out.println("Sorry you must be at least 18 years old");
        }
    }
}
