Java转换：char [] array - >串 [英] Java Converting: char[] array --> String

问题描述

如何将字符数组转换为字符串？


我有这个代码

  Console c = System.console（）; 
 if（c == null）{
 System.err.println（No console。）; 
 System.exit（1）; 
} 
 char [] password = c.readPassword（输入您的密码：）; 
  

我需要将其转换为String，才能验证

  if（stringPassword ==Password）{
 System.out.println（Valid）; 
} 
  

任何人都可以帮我吗？

$ b b

  char [] password = c.readPassword（输入您的密码：）; 
 String stringPassword = new String（password）; 
  

比较时，不要使用 == ，使用`.equals（）：

  if（stringPassword.equals（Password））{
  

How do you convert a character array to a String?
I have this code

Console c = System.console();
if (c == null) {
    System.err.println("No console.");
    System.exit(1);
}
char [] password = c.readPassword("Enter your password: ");

I need to convert that to a String so I can verify

if(stringPassword == "Password"){
    System.out.println("Valid");
}

Can anyone help me with this?

解决方案

Use the String(char[]) constructor.

char [] password = c.readPassword("Enter your password: ");
String stringPassword = new String(password);

And when you compare, don't use ==, use `.equals():

if(stringPassword.equals("Password")){
