java正则

public static Patter compile(String args):通过此方法取得Patter实例，并设置正则

public Matcher matcher(CharSequence input):为Matcher类实例化

public String[] split(CharSequence input):字符串拆分

public String pattern():返回正则表达式

import java.util.regex.Matcher;

import java.util.regex.Pattern;

public class Test {

    public static void main(String[] args) {
        String s1 = "DEF reference values true";
        String s2 = "DEF sex values female";
        String s3 = "DEF Array array1 values {3,4,5,6,5}";
        String s4 = "DEF Var name values Jack";
        String[] arr = { s1, s2, s3, s4 };
       
        String pat = "^DEF(Array|Var)?(.*?) values (.*)";
        Pattern p = Pattern.compile(pat);
        for (int i = 0; i < arr.length; i++) {
            Matcher m = p.matcher(arr[i]);
               //if(m.matches())是否匹配到

               if (m.find()) {
                String reg = m.group(2).trim();
                String regValue = m.group(3).trim();
                System.out.println(reg + "\tvalue: " + regValue);
              //替换 m.replaceAll("*");

            }
        }
    }
}

String类里支持正则表达式
