Question

JAVA 在控制台输入单词 直至输入end结束。并将已经学习的单词存放到字符串数组中

使用append方法追击字符串，并在每个单词后加分隔符“_”
将已经输入单词字符串转换为String类型 再调用String类split方法拆分字符串

Answer 1

public static void main(String[] args) {
String[] words = null;
words = getWords().toString().split("_");
for (int i = 0; i < words.length; i++) {
System.out.println(words[i]);
}

}

public static StringBuffer getWords() {
Scanner in = new Scanner(System.in);
String word = null;
StringBuffer sbf = new StringBuffer();
do {
System.out.println("请输入单词（end结束）:");
word = in.next();
sbf.append(word + "_");

} while (!word.equals("end"));

return sbf;
}

import java.io.*;
public class PrintDemo{
    public static void main(String[] args) throws Exception{
        BufferedReader out = new BufferedReader(new InputStreamReader(System.in));
        StringBuilder sb = new StringBuilder();
        while(true){
            System.out.println("请输入（end 结束输入）...");
            String line = out.readLine();
            if(!"end".equals(line))
                sb.append(line+"_");
            else
               break;
        }
        String[] str = sb.toString().split("_");
        for(String arrStr : str)
            System.out.println(arrStr);
    }
