Java中如何判断一个字符串的格式

/**
* check if the odivalue has a legal version format[0.0.0.0]
* @param odivalue:The odivalue extracted from SOAP
* @return :a boolean value,true or false
*/
public static boolean isCorrectVersion(String odivalue) {
// TODO Auto-generated method stub
Pattern pattern = Pattern.compile("[0-9]*" + "." + "[0-9]*" + "." + "[0-9]*" + "." + "[0-9]*");
Matcher isNum = pattern.matcher(odivalue);
if( !isNum.matches() )
{
return false;
}
return true;
}
采用java.util.regex.Matcher和java.util.regex.Pattern进行处理
