My First Java

[Nano Tape]

Hi and thanks for looking, Just started to learn Java and after reading various tutorials came up with this simple tables program. My question, is it as it should be? I mean it works OK but is it coded correctly?

import java.util.Scanner; // Import the Scanner class
public class MyTables {
public static void main(String[] args) {
int secondNum, answerNum;

Scanner sc = new Scanner(System.in);  // Create a Scanner object
System.out.println("Type a number:");
secondNum = sc.nextInt(); // Read user input	

for (int firstNum = 1; firstNum <= 12; firstNum ++) { 
answerNum = firstNum \* secondNum;
System.out.println(firstNum + " x " + secondNum + " = " + answerNum);
  }
}

}

It looks reasonable to me. The only thing I would say is that it is generally better to start loop counters from zero, as they are often used to access array items:

for (int firstNum = 0; firstNum < 12; firstNum ++) {
answerNum = firstNum * secondNum;
System.out.println(firstNum + " x " + secondNum + " = " + answerNum);
}

Also try to use consistent indentation, as it makes your code much easier to read. I don't know which tutorials you have been working on but The Java™ Tutorials[^] are some of the best for a beginner.

Useful article which was very helpful. also interesting and contains good information. Python programming language has advanced data structures and effective object-oriented programming concept that allows the developers to write concepts in fewer links than other programming languages. The simple syntax and dynamic typing feature make python as ideal programming language for scripting and rapid application development in many platforms. This programming language is used in leading companies like Google, Yahoo, CERN and even in NASA.

Yes you have done great work. I think you want to know have you done correct process(steps) in correct way. This process is known as algorithm in computer programming( c,c++, java etc). First write your steps in notebook or in notepad. then follow the steps. This is the general process for implementing any program.
