你好,我是正则表达式的新手,我不知道我在做什么.这就是我寻求帮助的原因.
我有以下电话号码359878123456,我需要检查电话号码是否符合标准.
> 359是确切的扩展名
>第二个2号码是操作符号码,以下是3个号码之一：87,88,89
>字符串中的下一个数字是2到9之间的数字
>和最后6个数字是0-9之间的任何数字
另外,我可以在检查中允许以下数字.
> 0878123456 – 其中0更改359的值
> 00359878123456 – 其中00改变了值
这就是我所处的位置
import java.util.regex.Matcher;
import java.util.regex.Pattern;
public class ValidatePhoneNumber {
public static void main(String[] argv) {
String sPhoneNumber = "+35987";
//String sPhoneNumber = "605-88899991";
//String sPhoneNumber = "605-888999A";
Pattern pattern = Pattern.compile("^\\+([3][5][9]){[87],[88],[89]}");
Matcher matcher = pattern.matcher(sPhoneNumber);
if (matcher.matches()) {
System.out.println("Phone Number Valid");
}
else
{
System.out.println("Phone Number Not Valid");
}
}
}
EDITED>
我正在检查数字是否符合该标准,只打印该行.
这是我的代码.
public static void main(String[] args) throws IOException {
// Pattern pattern = Pattern.compile("((\\+|00)359|0)8[7-9][2-9]\\d{6}$"); //checks evaluation of phone number
Pattern p = Pattern.compile("^((\\+|00)359|0)8[7-9][2-9]\\d{6}$");
File inFile = new File ("phonebook.txt");
Scanner sc = new Scanner (inFile);
while (sc.hasNextLine())
{
String line = sc.nextLine();
if(line.matches("^((\\+|00)359|0)8[7-9][2-9]\\d{6}$")) // here that code doesn't work
{
System.out.println (line);
}
}
sc.close();
}
解决方法
import java.util.regex.*;
public class Test{
public static void main(String[] args){
String mob="+359878123456";
Pattern p2 = Pattern.compile("^((\\+|00)359|0)(\\-|\\s)?8[7-9][2-9](\\-|\\s)?\\d{3}(\\s|\\-)?\\d{3}$");
boolean b = p2.matcher("+359-878-123456").matches();
if(b) System.out.println("True1");
b = p2.matcher("+359 878 123 456").matches();
if(b) System.out.println("True2");
b = p2.matcher("+359-878-123-456").matches();
if(b) System.out.println("True3");
b = p2.matcher("+359-878123456").matches();
if(b) System.out.println("True4");
b = p2.matcher("00359-878123456").matches();
if(b) System.out.println("True5");
b = p2.matcher("0-878-123456").matches();
if(b) System.out.println("True6");
b = p2.matcher("+359878123456").matches();
if(b) System.out.println("True7");
b = p2.matcher("359878123456").matches(); // without + or 00
if(b) System.out.println("True8");
else System.out.println("FALSE8");
b = p2.matcher("123478123456").matches();
if(b) System.out.println("True9");
else System.out.println("FALSE9");
}
}
