getpointinfom.java

使用k-means算法实现聚类分析,将四维的数据分成三个簇.

import java.io.*;
import java.util.*;
public class getPointInfom {
	public static void main(String[] args){
		ArrayList<String> arrays=read();
		System.out.println(" "+arrays.size());
		for(int i=0;i<arrays.size();i++) System.out.print(" "+arrays.get(i));
	}
	public static ArrayList<String> read(){
		ArrayList<String> arrays=new ArrayList<String>();
		try{
		BufferedReader in=new BufferedReader(new FileReader("src/pointInfom.txt"));
		String s="";
		String array="";
		while((s=in.readLine())!=null){
			array+=s;
		}
		//System.out.print(array);
		
		int i=0;
		s="";
		while(i<array.length()){
			if(array.charAt(i)=='('||array.charAt(i)==')'||array.charAt(i)==','){
				if(!s.equals("")){
					arrays.add(s);
					 s="";
				}
				i++;
			}
			else{
				s+=array.charAt(i);
				i++;
			}		
		}
	     
		}
		catch(IOException e){
			}
		return arrays;
		}
