程序代码：import java.util.*;
import *;
public class H7323 {
/**
* @param args
*/
public static void main(String[] args) {
Scanner a = new Scanner(System.in);
System.out.println("请输入用户名：");
String name = a.next();
Scanner b= new Scanner(System.in);
System.out.println("请输入密码：");
int pin = b.nextInt();
if (name=="青"&&pin==123){
System.out.print("欢迎你，青！");
}else{
System.out.print("对不起，你不是青！");
}
}

程序代码：
我这里一直这样....
import java.util.Scanner;
public class H7323 {
public static void main(String[] args) {
Scanner a = new Scanner(System.in);
System.out.println("请输入用户名：");
String name = a.next();
Scanner b = new Scanner(System.in);
System.out.println("请输入密码：");
int pin = b.nextInt();
if ( "青".equals(name) && pin == 123) {
System.out.print("欢迎你，青！");
} else {
System.out.print("对不起，你不是青！");
}
}
}哪位大神知道咋回事不？
