架构师之正则表达式(三)-------替换数组.

1.前言.
   如题.可以用正则表达式的group搞,这里直接替换.
2.代码.

import java.util.regex.Matcher;
import java.util.regex.Pattern;

public class Test {
	public static void main(String[] args) {
		String[] params = new String[] { "11", "22", "33", "44" };
		String templateString = "aaaa##bbbb##CCC##dddd##";
		for (int i = 0; i < params.length; i++) {
			templateString = templateString.replaceFirst("##", params[i]);
		}
		System.out.println("结果:" + templateString);
	}
}
