Q. Given the following piece of code:
class SalaryCalculationException extends Exception{}
class Person{
public void calculateSalary() throws SalaryCalculationException{
//...
throw new SalaryCalculationException();
//...
}
}
class Company{
public void paySalaries(){
new Person().calculateSalary();
}
}

Which of the following statements is correct?
1. This code will compile without any problems.
2. This code will compile if in method paySalaries() we return a boolean in stead of void.
3. This code will compile if we add a try-catch block in paySalaries().
4. This code will compile if we add throws SalaryCalculationException in the signature of method paySalaries().
