java - 字符串、模式匹配

Question

我可以这样构建字符串:

String str = "Phone number %s just texted about property %s";
String.format(str, "(714) 321-2620", "690 Warwick Avenue (679871)");

//Output: Phone number (714) 321-2620 just texted about property 690 Warwick Avenue (679871)

我想要实现的是相反的。输入将跟随字符串

电话号码 (714) 321-2620 刚刚发了关于 690 Warwick Avenue (679871) 特性的短信

我想从输入中检索“(714) 321-2620”和“690 Warwick Avenue (679871)”

谁能指点一下，如何在 Java 或 Android 中实现这一点？

提前谢谢你。

使用正则表达式:

String input = "Phone number (714) 321-2620 just texted about property 690 Warwick Avenue (679871)";
Matcher m = Pattern.compile("^Phone number (.*) just texted about property (.*)$").matcher(input);
if(m.find()) {
  String first = m.group(1); // (714) 321-2620
  String second = m.group(2); // 690 Warwick Avenue (679871)
  // use the two values
}

完整的工作代码:

import java.util.*;
import java.lang.*;
import java.util.regex.*;

class Main
{
  public static void main (String[] args) throws java.lang.Exception
  {
    String input = "Phone number (714) 321-2620 just texted about property 690 Warwick Avenue (679871)";
    Matcher m = Pattern.compile("^Phone number (.*) just texted about property (.*)$").matcher(input);
    if(m.find()) {
      String first = m.group(1); // (714) 321-2620
      String second = m.group(2); // 690 Warwick Avenue (679871)
      System.out.println(first);
      System.out.println(second);
  }
}
