Java集合練習題——從控制檯輸入若干個單詞（輸入回車結束）放入集合中，將這些單詞排序後（忽略大小寫）打印出來

import java.util.ArrayList;
import java.util.Iterator;
import java.util.List;
import java.util.Scanner;

public class SortWord {

	List<String> list=new ArrayList<>();
	Scanner input=new Scanner(System.in);
	boolean flag=true;
	String temp=null;
	
	public void write() {
		do {
			System.out.println("請輸入單詞（輸入0結束）：");
			temp=input.next();
			if(temp.equals("0")) {
				flag=false;
			}else {
				list.add(temp);
			}
		}while(flag);
		
		for (int i = 0; i < list.size(); i++) {
			for (int j = 0; j <list.size()-1-i; j++) {
				
				if(list.get(j).toUpperCase().compareTo(list.get(j+1).toUpperCase())>0) {
					temp=list.get(j);
					list.set(j,list.get(j+1));
					list.set(j+1, temp);
				}//if
			}//for
		}//for
		
		System.out.println("以下是從小到大的單詞排序");
		for (String str : list) {
			System.out.print(str+"\t");
		}
	
	}
}

import sortDemo01.SortLetter;

public class Test {

	public static void main(String[] args) {
		
		SortWord sl=new SortWord();
		sl.write();
	}
}
