动手动脑二

1.

 

package random;
import java.util.Random;
import java.util.Scanner;

public class randomInt {
    
    static Scanner inputScanner = new Scanner(System.in);

    public static void main(String[] args) {
        // TODO Auto-generated method stub
        int n = inputScanner.nextInt();
        int i;
        Random random = new Random(System.currentTimeMillis());
        for (i=0;i<n;i++)
        {
            System.out.println((i+1)+"、"+random.nextInt());
        }

    }

}

2.可变参数

 

package example;

public class exam {

    public static double max(double...values)
    {
        double largest=Double.MIN_VALUE;
        for (double v:values) 
            if(v>largest) largest=v;
        return largest;
    }
    public static void main(String args[]) {
        
         System.out.println("Max:"+max(1,11,300,2,3));
            
    }
}

3.大整数
