기본 Java 코드를 컴파일하는 중 오류가 발생했습니다.

Question

java를 처음 사용하였습니다. 책을 따라 코딩 연습. Heres는

내 코드 : 내가 컴파일 할 때

class Motorcycle { 


    //Three instance variables - make and color are strings. while a boolean refers to TRUE OR FLASE(in this case off or on) 
    String make; 
    String color; 
    boolean engineState; 

    void startEngine() { 
     if (engineState == true) 
      System.out.print("The engine is already on."); 
     else { 
      engineState = true; 
      System.out.print("The engine is now on."); 

     } 

    void showAtts() { 
     System.out.print("This motorcycle is a " + color + " " + make); 
     if (engineState ==true) 
      System.out.print("The engine is on."); 
     else System.out.print("The engine is off."); 

    } 
}

문제점을 지적 할 수 없습니다. 누구든지 나를지도하거나 힌트를 주시면 제발 할 수 있습니다.

Answer 1

그것은이 하나를 시도 오류없이 올바른 형식입니다 ..

public class Motorcycle { 

public static void main(String[] args) { 
    Motorcycle s=new Motorcycle(); 
    s.showAtts(); 
    s.startEngine(); 
} 

//Three instance variables - make and color are strings. while a boolean refers to TRUE OR FLASE(in this case off or on) 
String make; 
String color; 
boolean engineState; 

void startEngine() { 
    if (engineState == true) 
     System.out.println("The engine is already on."); 
    else { 
     engineState = true; 
     System.out.println("The engine is now on."); 

    } 
} 
void showAtts() { 
    System.out.print("This motorcycle is a " + color + " " + make); 
    if (engineState ==true) 
     System.out.println("The engine is on."); 
    else System.out.println("The engine is off."); 

} 

} 

Answer 2

중괄호 중 하나가 잘못된 위치에 있습니다. 해야합니다

class Motorcycle { 

//Three instance variables - make and color are strings. while a boolean refers to TRUE OR FLASE(in this case off or on) 
    String make; 
    String color; 
    boolean engineState; 

    void startEngine() { 
    if (engineState == true) 
     System.out.print("The engine is already on."); 
    else { 
     engineState = true; 
     System.out.print("The engine is now on."); 
    } 
    } 
    void showAtts() { 
    System.out.print("This motorcycle is a " + color + " " + make); 
    if (engineState ==true) 
     System.out.print("The engine is on."); 
    else System.out.print("The engine is off."); 
    } 
} 

Answer 3

방법 startEngine는 닫는 중괄호 중괄호가없는, 또 다른 예비 닫는 중괄호 당신은 showAtts() 방법 startEngine() 방법 내부에 정의 된 코드

Answer 4

의 끝 부분에있다. 메소드는 다른 메소드의 정의를 가질 수 없습니다.

이것은 중괄호가 잘못 배치되었을 수 있습니다. 그들을 정정하십시오.

Answer 5

class Motorcycle { 

    // Three instance variables - make and color are strings. while a 
    // boolean refers to TRUE OR FLASE(in this case off or on) 
    String make; 
    String color; 
    boolean engineState; 

    void startEngine() { 
     if (engineState == true) 
      System.out.print("The engine is already on."); 
     else { 
      engineState = true; 
      System.out.print("The engine is now on."); 

     } 
    } 

    void showAtts() { 
     System.out.print("This motorcycle is a " + color + " " + make); 
     if (engineState == true) 
      System.out.print("The engine is on."); 
     else 
      System.out.print("The engine is off."); 

    } 
}
