Why cannot we use static keyword inside a method in java?

Questions is how can we use if statements in writing our own method in java?

• like i am doing 3 caculations in my own method with if statements but i am unable to do so. This is my own method that i have written public static double calculateFine (double velocity) { if ((velocity > 20) || (velocity < 31)) { double velocity2 = velocity * 3.00; return velocity2; } else if ((velocity < 30) || (velocity <= 40)) { double velocity2 = velocity * 8.00; return velocity2; } else if (velocity > 40) { double velocity2 = velocity * 12.00; return velocity2; } }

• Answer:

  There's nothing wrong with your code, but your logic is a bit off. In the first if statement, you probably mean AND (&&) rather than OR (||). In the second you probably want to say "velocity > 30 && velocity <=40."
