Java读取文件并逐行打印众名&末行字符串保留方法"以寻找众名实验为例"

import java.io.*;  
import java.util.Scanner;
public class Q9 {

	public static void main(String[] args) 
			throws FileNotFoundException {
		// TODO Auto-generated method stub
		Scanner input = new Scanner (new File("/Users/apple/Documents/Class Folders/Java/Lab6/Q9.txt"));//读取文件
		
		int uniquenam=0;
		while(input.hasNextLine()) {
			String repeatname="xx";
			String name ="x";
			String firstname = "x";
			String comName = "xxx";
			int count =1;
			
			int record = 1;
			String line = input.nextLine();
			Scanner lineScan = new Scanner (line);
			while (lineScan.hasNext()) {
				name=lineScan.next();
				if(repeatname=="xx") {
					comName=name;
				}	//默认最多的名字为第一位
				if(name.equals(repeatname)) {
					count++;
				}else if(!name.equals(repeatname)&&count>record){
					comName = repeatname;
					record = count;
					count=1;
					uniquenam++;
				}else {
				
					uniquenam++;
					count=1;
				}
				repeatname = name;
				
			}
		
			if(!lineScan.hasNext()&&count>record){
				comName = repeatname;
				record = count;
				count=1;
				
			}//在最后一个字符串出现的时候保证不会传递到下行
			
			System.out.println("Most common:"+comName);
			System.out.println(record);
			
		}
		System.out.println(uniquenam);
	}
