[英]user input validation java classes
This is my validation for user ID number, when testing, I entered an invalid string with a length less than 10 and it sets the input and doesn't execute the else statement. 这是我对用户ID号的验证,在测试时,我输入了长度小于10的无效字符串,它设置了输入并且不执行else语句。
private String phoneNum;
public personalInfo(String phNum) {
setPhoneNum(phNum);
}
public String getPhoneNum() {
return phoneNum;
}
public void setPhoneNum(String phNum) {
if (phoneNum.startsWith("05")&&(phoneNum.length()==10)){
phoneNum = phNum;
}
else throw new IllegalArgumentException ("Invalid Phone Number!");
}
your method looks like this... 你的方法看起来像这样...
public void setPhoneNum(String phNum) {
if (phoneNum.startsWith("05")&&(phoneNum.length()==10)){
phoneNum = phNum;
}
and there you are not validating the parameter, but the variable phoneNum
... 并且您没有验证参数,而是变量
phoneNum
...
do instead: 改为:
public void setPhoneNum(String phNum) {
if (phNum.startsWith("05")&&(phNum.length()==10)){
phoneNum = phNum;
}
You should be validating the value you that you are getting ( phNum
) and set it to the member variable phoneNum
. 您应该验证要获取的值(
phNum
),并将其设置为成员变量phoneNum
。
if (phNum.startsWith("05")&&(phNum.length()==10)){
phoneNum = phNum;
}
