输入任意正整数a,b,c，返回最大值

输入任意正整数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);实现界面输入数据
2.源代码如下：

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("请输入第一个数值：");
        a = in.nextInt();
        System.out.print("请输入第二个数值：");
        b = in.nextInt();
        System.out.print("请输入第三个数值：");
        c = in.nextInt();
int max = a;
if (b > max)
            max = b;
else if (c > max)
            max = c;
        System.out.print("最大值为："+max);
    }
}

3.运行结果：
