java - 根据单词在java中拆分字符串

Question

如何将字符串 say "The Lazy dog is running fast"与 "dog"分开，以便我得到字符串 ="The Lazy", "dog","is running fast"？在Java中

我正在使用的代码 String str="这只懒狗跑得像条狗"; 串狗=“狗”; String[] strArr= str.split(狗); 对于(int i = 0;我

它返回:懒人 运行得像一个

Answer 1

我建议使用 regular expressions (和分组)。正则表达式几乎可以用来匹配任何你想要的东西!

例如

import java.util.regex.*;

public class PatternExample {

    public static void main(String[] args) {
        String split = "The Lazy dog is running fast";
        Pattern pattern = Pattern.compile("(.*)(dog)(.*)");
        Matcher matcher = pattern.matcher(split);
        while (matcher.find()) {
            for (int i = 0; i <= matcher.groupCount(); i++){
                System.out.println(i + "->" + matcher.group(i));
            }
        }
    }
}

给予:

0->The Lazy dog is running fast
1->The Lazy 
2->dog
3-> is running fast

练习 2:没有正则表达式

public class PatternExample {

    public static void main(String[] args) {
        String split = "The Lazy dog is running fast";
        String word = "dog";
        String tmp = split;
        while (tmp.contains(word)){
            int x = tmp.indexOf(word);
            System.out.println(tmp.substring(0,x));
            System.out.println(word);
            tmp = tmp.substring(x+word.length());
        }
        System.out.println(tmp);
    }
}
