How could I put 2 program in one code in Java?

Question

Linking Program.
A code in Java wherein a two different type of program is being put together. For example, Simple calculator and Temperature convertion in one code. Output might be like this:
Choose a program(click 1 for simple calculator and 2 for temperature convertion)
/**for example I choose 1.
1
/**then the simple calculator will appear on the screen

Answer 1

For code clarity define two separate functions and call them according to the initial input value.

Answer 2

I had in mind something like:
import java.util.*;
public class Main
{
public static void main(String[] args)
{
System.out.println("Choose '1' or '2':");
System.out.println("1. Calculator");
System.out.println("2. Converter");
Scanner input = new Scanner(System.in);
String app = input.nextLine();
if (app == "1")
{
Calculator();
}
if (app == "2")
{
Converter();
}
}
}

/* you just need to define the functions themselves, as each of them will be doing a different thing, probably asking for different types of data, ultimately */

Answer 3

I realize, but the logic will be the same whether GUI or non-GUI. Although for GUI this actually would be an event-based code structure, most likely.

Answer 4

Use switch, in this case.

Answer 5

@kuba ,

he is thinking that it is java (gui) here where we can make forms to take input
but its java (non-gui) here ....he needs to understand this

Answer 6

hey bro u need to take a single input

then apply method1 on input //for temperature , let it be from celcius to kelvin
then apply method2 on input//for calaculator , let it be u need its sum with 2

and print output though each method

note : here , it is java (non-gui)
&might u be usinv java (gui) through netbeans , thats why u r asking this question

Answer 7

Mr. Siekierzyński, what function should I use in able to do it?

Answer 8

not on here dude best you use gui for that type of interface.

i made a very simple tempture converter if you like to see might get an idea how java works on here

i could intergate a calculator but would have to run both thorough the scanner.
