在eclipse下开发的求平面上两点之间的最短距离。通过随机在平面上生成无数个点

package distance;

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.util.Random;
import java.lang.Math;

public class Test {
	public int NumOfPoints;

	public static void main(String[] args) throws IOException{
		//int NumOfPoints = (int) Math.pow(2,3);
		//Random random1 = new Random(100);
		//double num = 10*(new Random()).nextDouble();
		//System.out.println("n is:" + NumOfPoints);
		//System.out.println("the num is:" + random1.nextDouble());
		//System.out.println("the wanted num is:" + num);
		System.out.println("plz input the value of n:");
		//int n = (int)System.in.read();
		BufferedReader reader = new BufferedReader(new InputStreamReader(System.in));
		String n = reader.readLine().trim();
		int nn = Integer.parseInt(n);
		
		System.out.println("n is:" + n);
		System.out.println("nn is:" + nn);
		int NumOfPoints = (int) Math.pow(2,nn);
		
		//int NumOfPoints = (int) Math.pow(2,Integer.parseInt(reader.readLine().trim()));
		System.out.println("NumOfPoints is:" + NumOfPoints);
