Can someone help me seperate this code to make a Fraction.java class and a Fract

Question

Can someone help me seperate this code to make a Fraction.java class and a FractionApp.java class so that the FractionApp.java excutes the code for both classes in the command prompt.

This is the code:

import java.io.*;
import java.util.Scanner;
class FractionApp {
class Fraction{
private int nomo;
private int deno;
Fraction(){nomo=0;deno=1;}
Fraction(int n,int d){nomo=n;deno=d;}
  
}
private static Fraction f1;
private static Fraction f2;

public static void main(String[] args) {
int choi;
Scanner sc=new Scanner(System.in);
FractionApp FC=new FractionApp();
Fraction f;
printMenu();
System.out.print("Choose one operation:");
choi=sc.nextInt();
switch(choi){
case 1: FC.getInput();
f=FC.addFraction(f1,f2);
System.out.format(" Result:%d/%d ",f.nomo,f.deno);
break;
case 2: FC.getInput();
f=FC.subtractFraction(f1,f2);
System.out.format(" Result:%d/%d ",f.nomo,f.deno);
break;
case 3: FC.getInput();
f=FC.multiplyFraction(f1,f2);
System.out.format(" Result:%d/%d ",f.nomo,f.deno);
break;
case 4: FC.getInput();
f=FC.divideFraction(f1,f2);
System.out.format(" Result:%d/%d ",f.nomo,f.deno);
break;
default: System.out.println("Invalid choice!");
   }
}

public Fraction addFraction(Fraction f1,Fraction f2) {
Fraction resul=new Fraction();
resul.nomo=(f1.nomo*f2.deno)+(f1.deno*f2.nomo);
resul.deno=f1.deno*f2.deno;
return resul;
}
public Fraction subtractFraction(Fraction f1,Fraction f2){
Fraction resul=new Fraction();
resul.nomo=(f1.nomo*f2.deno)-(f1.deno*f2.nomo);
resul.deno=f1.deno*f2.deno;
return resul;
}
public Fraction multiplyFraction(Fraction f1,Fraction f2){
Fraction resul=new Fraction();
resul.nomo=f1.nomo*f2.nomo;
resul.deno=f1.deno*f2.deno;
return resul;
}
public Fraction divideFraction(Fraction f1,Fraction f2){
Fraction resul=new Fraction();
resul.nomo=f1.nomo*f2.deno;
resul.deno=f1.deno*f2.nomo;
return resul;
}
public static void printMenu(){
System.out.println("FRACTIONS CALCULATOR");
System.out.println("-------------------------------");
System.out.println("1. Add fractions");
System.out.println("2. Subtract fractions");
System.out.println("3. Multiply fractions");
System.out.println("4. Divide fractions");
}
public void getInput(){
String[] ftext=new String[2];
String[] sptext=new String[2];
int no,de;
f1=new Fraction();
f2=new Fraction();
int i;
  
try{
for(i=0;i<=1;i++){
BufferedReader br=new BufferedReader(new InputStreamReader(System.in));
System.out.format("Enter fraction %d (e.g. 1/2):",i+1);
ftext[i]=br.readLine();

}
sptext=ftext[0].split("/");
f1.nomo=Integer.parseInt(sptext[0]);
f1.deno=Integer.parseInt(sptext[1]);

sptext=ftext[1].split("/");
f2.nomo=Integer.parseInt(sptext[0]);
f2.deno=Integer.parseInt(sptext[1]);
if(f1.deno==0 || f2.deno==0) { System.out.println("A denominator can't be zero."); System.exit(100);}

       }catch(IOException e){System.out.println("Error in reading user input...");}
   }
}

If you could clearly seperate the difference that would be great! thank you for the help in advance!

Explanation / Answer

The code what u have given is entairly one program only

defined one class in another call only
