SOLID is a set of five object-oriented design principles that help developers write code that is maintainable, scalable, flexible, and easy to test.
S — Single Responsibility Principle (SRP)
A class should have only one reason to change.
class Employee {
public void calculateSalary() {
// Salary calculation
}
public void saveToDatabase() {
// Database logic
}
public void generateReport() {
// Report generation
}
}class Employee {
private String name;
private double salary;
// getters/setters
}
class SalaryCalculator {
public double calculate(Employee employee) {
return employee.getSalary();
}
}
class EmployeeRepository {
public void save(Employee employee) {
// Save to DB
}
}
class ReportGenerator {
public void generate(Employee employee) {
// Generate report
}
}
Yes, I understand it. I hear a lot of this incorrect grammar from my wife. I would expect that the person that spoke this was possibly Chinese. In Chinese there are no tenses or plurals. No he or she pronouns. The context tells all. So it might have been a direct translation from Chinese.
There is a certain poetic sense in which “I see” works. “I see him last night in my dreams” although not technically correct. However, generally speaking “I saw” is the right usage for past events. Much prose writing in English novels is in the present tense although they are about past events. The author superimposes himself however on the situation as if it were the present.
No, ‘I see him last night’ is always incorrect and will be only just barely understandable. It is a very serious and basic error, and it will be tiring for a native speaker to converse with someone who speaks like this, because they will constantly have to be remembering what the person really means. It will not be ‘immediately obvious without thinking about it’.
Someone just asked this question recently, and I replied, saying that ‘I see him last night’ is never correct. That is exactly what i meant.
You are correct that both are understandable.
The only other possible everyday meaning I could think of would be ‘I see him [in my mind’s eye] last night’; that is, I am, at this very moment, imagining him last night. But it should almost always be clear from context which one is intended.
‘Correct’ doesn’t mean ‘understandable’, though. If I say ‘Me want have fooding’ it’s pretty clear what to understand from that, but it’s not anywhere near correct Standard English grammar. If you lived somewhere where you spoke a dialect of English in which this was acceptable grammar, however, then it would be correct for that dialect.
