How can we use input from one class to another ?

Question

Need to use input from one class and use it in another class functions

Answer 1

I need to convert this code into java
#include <iostream>

using namespace std;

class gajjar
{
double a,b;
public:
void read()
{
cout<<"\nEnter two double type numbers:";
cin>>a>>b;
}
void div()
{
try{

if(cin.fail())
throw "Bad input!";
if( b == 0 )
throw 0;

cout<<"\nAns is "<<a/b;
}
catch(const int n)
{
cout << "\nDivision by " << n << " not allowed\n";
}
catch(const char* Str)
{
cout<< Str;
}
}
};

int main()
{
gajjar k;
k.read();
k.div();
return 0;
}

Answer 2

//Tried but not working
import java.util.Scanner;
public class Solution {

public static void main(String[] args) {
Scanner sc=new Scanner(System.in);
System.out.println("Enter two double");
double x=sc.nextDouble();
double y=sc.nextDouble();
System.out.println("Double: "+x);
System.out.println("Double: "+y);

}
}
public class Example {
public static void main(String[] args) {

Solution a=new Solution();
double p=a.x;
double q=a.y;

System.out.println(divisionFunction(p, q)); }

public static int divisionFunction(double dividend, double divisor) {
int quotient;
if (divisor == 0.0) {
throw new IllegalArgumentException("Argument 'divisor' is 0");
} else {
return quotient = (int) (dividend / divisor);
}
}
}
