do-while循环中的问题 [英] problem in do-while loop
问题描述
如果键入匹配，则循环不能停止.有人可以解决这个问题并告诉我我的错误吗?
如果能的话，请多谢！
<br />import java.io.*;<br /><br />public class A<br />{<br />public static void main(String args[]) throws IOException<br />{<br />BufferedReader stdin=new BufferedReader (new InputStreamReader(System.in));<br />//char n,p;<br />String name,pwd;<br />int n1;<br />int p2;<br /><br />System.out.println("\tWelcome to ");<br />System.out.println("*******SHINE IT Training Centre*******");<br />System.out.println("**Please login before u calculate**");<br /><br />do<br />{<br />System.out.println("Enter user name: ");<br />name=stdin.readLine();<br />n1=Integer.parseInt(name);<br />System.out.println("Enter password: ");<br />pwd=stdin.readLine();<br />p2=Integer.parseInt(pwd);<br /><br />//System.out.println("Incorrect input!!");<br />} while ((name!="2208")&&(pwd!="1234"));<br /><br /><br />System.out.println("Successful Login!!");<br /><br />}<br />}<br />
The loop cant be stop eventho the key-in matches. Can anyone fix this and tell me my mistake?
Greatly appreciate it if so! <br />import java.io.*;<br /><br />public class A<br />{<br />public static void main(String args[]) throws IOException<br />{<br />BufferedReader stdin=new BufferedReader (new InputStreamReader(System.in));<br />//char n,p;<br />String name,pwd;<br />int n1;<br />int p2;<br /><br />System.out.println("\tWelcome to ");<br />System.out.println("*******SHINE IT Training Centre*******");<br />System.out.println("**Please login before u calculate**");<br /><br />do<br />{<br />System.out.println("Enter user name: ");<br />name=stdin.readLine();<br />n1=Integer.parseInt(name);<br />System.out.println("Enter password: ");<br />pwd=stdin.readLine();<br />p2=Integer.parseInt(pwd);<br /><br />//System.out.println("Incorrect input!!");<br />} while ((name!="2208")&&(pwd!="1234"));<br /><br /><br />System.out.println("Successful Login!!");<br /><br />}<br />}<br />
推荐答案
更改
while((name！="2208")&& ;(pwd！="1234"));
到
同时((！name.equals("2208"))&&(！pwd.equals("1234" )));
或
而while(((n1！= 2208)&&(p2！= 1234));
;-P ;-P; -P ;-P
eigther change
while ((name!="2208")&&(pwd!="1234"));
to
while ((!name.equals("2208"))&&(!pwd.equals("1234")));
or
while ((n1!=2208)&&(p2!=1234));
;-P ;-P ;-P ;-P
