重载

命令行传参


可变参数:

//不确定给我传入多少个参数
代码如下:

public class PARAMS {


    public static void main(String[] args) {
        printMax(34,3,3,2,56);
        printMax(new double[]{1,2,3});
    }

    public static void printMax(double... numbers){
        if(numbers.length ==0){
            System.out.println("No argument passed");
            return;
        }
        double result =numbers[0];

        //排序
        for (int i = 0; i <numbers.length ; i++) {
            if(numbers[i] >result){
                result = numbers[i];
            }
        }
        System.out.println("The max value is "+result);


    }
}
输出结果:
The max value is 56.0
The max value is 3.0
