三

public class SecondClass{

    static int x;

    public SecondClass(){}

    public SecondClass(int num){
        x = num;
    }
    public SecondClass(int num, int number){
        x += num + number;
    }

    public static void main(String[] args) {
        int a = 10;
        int b = 10;
        int c = a + b * a / b - b;
        try {
            if (c == 0){

            }else if(c == 10){

            }else {

            }
        } catch (Exception e) {
            e.printStackTrace();
        }finally {
            
        }
    }
