我正在尝试完成一项家庭作业,并不断收到两个错误,无法弄清楚如何解决它们。这是代码:
import java.util.Scanner;
public class GoughAndreaProg5
{
public static void main (String[] args)
{
Scanner stdIn = new Scanner(System.in);
System.out.println("Enter a password that meets the following rules: ");
System.out.println("");
System.out.println("Is atleast 8 characters long");
System.out.println("Contains atleast 1 lower letter character");
System.out.println("Contains atleast 1 upper letter character");
System.out.println("Contains atleast 1 numeric digit");
System.out.println("Contains atleast 1 special character from the set: !@#$%^&*");
System.out.println("Does not contain the word \"and\" or the word \"end\"");
System.out.println("");
String myInput = stdIn.nextLine();
boolean digit = false;
boolean upperCase = false;
boolean lowerCase = false;
for(int x=0; x<myInput.length(); x++)
{
if (Character.isDigit(myInput.charAt(x)))
digit = true;
if(Character.isUpperCase(myInput.charAt(x)))
upperCase = true;
if(Character.isLowerCase(myInput.charA(x)))
lowerCase = true;
}
boolean validLength = true;
if (myInput.length() < 8)
{
System.out.println("Must be at least 8 characters long");
validLength = false;
}
boolean special = false;
if(myInput.indexOf('!') != -1 | myInput.indexOf('@') != -1 || myInput.indexOf('#') != -1 || myInput.indexOf('$') != -1 || myInput.indexOf('%') != -1 || myInput.indexOf('^') != -1 || myInput.indexOf('&') != -1 || myInput.indexOf('*') != -1)
special = true;
else //no special character
{
System.out.println("Must contain a special character");
}
boolean word = false;
if (myInput.indexOf("and") != -1 || myInput.indexOf("end"));
{
word = true;
System.out.println("Contains the string \"and\" or the word \"end\"");
}
if(!digit)
System.out.println("Must have a numeric digit");
if(!upperCase)
System.out.println("Must have an upper case");
if(!lowerCase)
System.out.println("Must hava a lower case");
//output valid or not
if (validLength && special && !word && upperCase && lowerCase && digit)
System.out.println("valid");
else
System.out.println("not valid");
} //end main method
public static void System.out.println(String inStr)
{
System.out.println(inStr);
} //end of alt string print method
} //end of class
错误是:
C:\Users\gougha\Documents\Park\Java Class\myJavaPgms\GoughAndreaProg5.java:76: error: '(' expected
public static void System.out.println(String inStr)
^
C:\Users\gougha\Documents\Park\Java Class\myJavaPgms\GoughAndreaProg5.java:76: error: <identifier> expected
public static void System.out.println(String inStr)
^
我已经尝试了所有我能想到的东西。我敢肯定这是一个简单的解决方法,但这对我来说太新了,我看不到。谢谢!
您的代码有几个编译错误
开始
public static void System.out.println(String inStr)
应该是(尽管您不使用它,所以我建议您删除此方法)
public static void println(String inStr)
然后
if (myInput.indexOf("and") != -1 || myInput.indexOf("end"));
应该
if (myInput.indexOf("and") != -1 || myInput.indexOf("end") != -1);
最后
if(Character.isLowerCase(myInput.charA(x)))
应该
if(Character.isLowerCase(myInput.charAt(x)))
