我一直在苦苦挣扎4个小时,但我输入密码的字符串并没有检查长度条件。我知道我在做一些愚蠢的错误,但不幸的是我无法弄明白。最后,我决定在这里向专家们提问,请帮助我。
PS:我正在编写一个函数来验证密码长度为4到11个字符,包含一个大写字符,一个小写字符,一个数字和一个特殊字符。
public void validPassword(){
String password;
boolean con = true;
Pattern[] passRegex = new Pattern[4];
{
passRegex[0] = Pattern.compile(".*[A-Z].*");
passRegex[1] = Pattern.compile(".*[a-z].*");
passRegex[2] = Pattern.compile(".*\\d.*");
passRegex[3] = Pattern.compile("[A-Za-z0-9]*");
}
while(con){
System.out.println("Enter Your Password Using Correct Format:");
password = input.next();
if(password.length() < 4 && password.length() > 11){
System.out.println("Your Password Should Be 4 To 11 Characters Long");
}
if(!passRegex[0].matcher(password).matches()){
System.out.println("Your Password Must Contain Atleast One UpperCase Letter");
}
if(!passRegex[1].matcher(password).matches()){
System.out.println("Your Password Must Contain Atleast One LowerCase Letter");
}
if(!passRegex[2].matcher(password).matches()){
System.out.println("Your Password Must Contain Atleast One Digit");
}
if(passRegex[3].matcher(password).matches()){
System.out.println("Your Password Must Contain Atleast One Special Character");
}
else{
System.out.println("Your Password Is Correct");
con = false;
}
}
}
答案 0 :(得分:0)
你需要或在你的第一个条件不是和
if(password.length() < 4 || password.length() > 11){
不是
if(password.length() < 4 && password.length() > 11){
