java - 伊拉克电话号码的java正则表达式

Question

我需要一个正则表达式来匹配这个电话号码模式：

• 它总是以 07 开头
• 然后是这个范围内的数字（3-9）
• 它必须是 11 个字符

示例：07902848117

07796938209

07302819248

Answer 1

Try this, it should work.

"07[3-9][0-9]{8}"  

What this mean is,   
07 - it tries to find literally 07  
[3-9] - then followed by 3 to 9, only one time
[0-9] - then followed by 0 to 9  
{8} - text previous to this should has at least 8 characters.
