我的题解 | 类型转换
import java.util.Scanner;
public class Main {
public static void main(String[] args) {
Scanner scanner = new Scanner(System.in);
double d = scanner.nextDouble();
System.out.println(Main.typeConversion(d));
}
public static int typeConversion(double d){
//装箱给Double
Double dou = d;
return dou.intValue();
}
}
装箱给Double类型然后通过intValue方法转换成int
