麻煩在Java中的類

Question

我有點困惑，因爲我無法弄清楚我在這裏做錯了什麼。我做了幾乎所有我可以做的事情，但仍然無法正常工作。我現在無言如何從這裏前進。請幫助，我真的很感謝你的可能解決方案。由於

public class Example { 


public static void main(String[] args) { 


    String cafescan; 

    Scanner scan= new Scanner (System.in); 

     System.out.print ("Please enter the name of the cafe :"); 
     cafescan = scan.nextLine(); 

     Cafe naam = new Cafe(); 
     naam.name = (cafescan);//THIS WORKS FINE 
     Cafe thau = new Cafe(); 
     thau.location = (location1);//THIS IS WHERE ERROR IS 
       System.out.println (naam.setName()); 
      System.out.print (thau.setLocation()); 

在我Cafe.jave文件我有這樣的：

public class Cafe{ 
String name; 
String location; 



    public String setName(){ 

     name=name.substring(0, 1).toUpperCase() + name.substring(1).toLowerCase()+ " Cafe"; 
     return name; 
    } 

    public String setLocation(){ 
     char location1 = name.charAt(0); 
     //SWITCH IS SUPPOSED TO WORK ACCORDING TO FIRST ALPHABET OF cafescan 

     switch (location1) 
     { 
     case 'E': 
      System.out.println("Rosedale"); 
      break; 
     case 'M': 
      System.out.println ("Parkville"); 
      break; 
     case 'T': 
      System.out.println ("Towson"); 
      break; 
      default: 
       System.out.println("Baltimore"); 


     } 
     return location; 
    } 

}

幫我出大師:)

Answer 1

首先必須聲明LOCATION1。和他們讀，從您的掃描儀

String location1= scan.nextLine(); 

Answer 2

在main方法使咖啡對象如下：

Cafe naam = new Cafe(cafescan); 

修改您的網吧類，如下所示：

public class Cafe{ 
    String name; 
    String location; 


public Cafe(String name){ 
    setName(); 
    setLocation(); 
} 

public String setName(){ 

    name=name.substring(0, 1).toUpperCase() + name.substring(1).toLowerCase()+ " Cafe"; 
    return name; 
} 

public String setLocation() { 
    char location1 = name.charAt(0); 
    // SWITCH IS SUPPOSED TO WORK ACCORDING TO FIRST ALPHABET OF cafescan 

    switch (location1) { 
     case 'E': 
      System.out.println("Rosedale"); 
      location = "Rosedale"; 
      break; 
     case 'M': 
      System.out.println("Parkville"); 
      location = "Parkville"; 
      break; 
     case 'T': 
      System.out.println("Towson"); 
      location = "Towson"; 
      break; 
     default: { 
      System.out.println("Baltimore"); 
      location = "Baltimore"; 
     } 

    } 
    return location; 
} 

}
