//1.创建匹配模式
Pattern pattern = Pattern.compile("10\\.255\\.130\\.32|192\\.168\\.100\\.10");//匹配一个或多个数字字符
//2.选择匹配对象
Matcher matcher = pattern.matcher(str);
//与谁匹配?与参数字符串str匹配
int count = 0;
while (matcher.find())//matcher.find()用于查找是否有这个字符,有的话返回true
{
System.out.println("第" + (++count) + "次找到");
//start()返回上一个匹配项的起始索引
//end()返回上一个匹配项的末尾索引。
System.out.println(str.substring(matcher.start(),matcher.end()));

Java regularizes multiple IPs to find out the matching results
