Question

符号在那里是“;”，所以我不确定语法中的问题是什么。

//Vet Application
import java.io.PrintStream;

public class VetApp
{
public static void main(String[] paramArrayOfString)
{
Dog newDog1 = new Dog();
Dog newDog2 = new Dog(2, "Ruff");
System.out.println();

System.out.println();
newDog1.print();
System.out.println();
newDog2.print();

扫描程序localScanner =新扫描程序（System.in）;

System.out.print("What is the new breed of the first dog? ");
int i = localScanner.nextInt();
newDog1.setBreed(i);
System.out.println();
System.out.println();
newDog1.print();

System.out.print("What is the breed of the second dog? ");
i = localScanner.nextInt();
newDog2.setBreed(i);
System.out.println();
System.out.println();
newDog2.print();

System.out.print("What sound does the first dog make? ");
String str = localScanner.next();
newDog1.setSound(str);
System.out.println();
System.out.println();
newDog1.print();

（部分程序被省略）

以下是错误消息：

c:\jwork>javac VetApp.java
MontelWhite_VetApp.java:17: error: cannot find symbol
Scanner localScanner = new Scanner (System.in);
^

Scanner localScanner = new Scanner (System.in);
                           ^

2 errors

如果需要，我还有“Dog”类源代码。我错过/遗忘了什么？

Answer 1

您忘记添加java.util.Scanner的导入。因此，将其添加到您的类文件之上，如下所示：

import java.util.Scanner;
import java.io.PrintStream;

public class VetApp {
    /* Code omitted */
}
