題目說明

給一整數，用副程式回傳絕對值

輸入限制：整數

※請勿使用Math函式作答※

vvv使用以下程式碼作答vvv

import java.util.Scanner;

public class AbsoluteValue{

    public static void main(String[] args) {
        Scanner in = new Scanner(System.in);
        int a = in.nextInt();
        in.close();
        System.out.print(abs(a));
    }

    public static int abs(int a) {
        // 在此補足缺少的程式碼
        // 記得return
    }

}

題解

import java.util.Scanner;

public class AbsoluteValue {

    public static void main(String[] args) {
        Scanner in = new Scanner(System.in);
        int a = in.nextInt();
        in.close();
        System.out.print(abs(a));  // 呼叫副程式
    }

    public static int abs(int a) {
        return (a >= 0) ? a : -a;
    }

}
