輸入任意正整數a,b,c，返回最大值

1.本文用到了java.util.Scanner包，利用Scanner in = new Scanner(System.in);實現界面輸入數據
2.源代碼如下：

package chapter1;
import java.util.Scanner;
public class one {
    /**
     * @param args
     */
    public static void main(String[] args) {
        // TODO Auto-generated method stub
        Scanner in = new Scanner(System.in);
        int a = 0, b = 0, c = 0;
        System.out.print("請輸入第一個數值：");
        a = in.nextInt();
        System.out.print("請輸入第二個數值：");
        b = in.nextInt();
        System.out.print("請輸入第三個數值：");
        c = in.nextInt();
        int max = a;
        if (b > max)
            max = b;
        else if (c > max)
            max = c;
        System.out.print("最大值爲："+max);
    }
}

3.運行結果：
