Java格式化手机号和身份证号，中间使用星号*隐藏

package com.example.core.mydemo.java;

/**
 * renterMobile=111****1198
 * idNo=456666********5916
 */
public class HiddleStringTest {
    public static void main(String[] args) {
        String renterMobile = "11133331198".replaceAll("(\\d{3})\\d*(\\d{4})","$1****$2");
        System.out.println("renterMobile=" + renterMobile);

        String idNo = "456666199002175916".replaceAll("(\\d{6})\\d*(\\d{4})","$1********$2");
        System.out.println("idNo=" + idNo);

    }

}
