java.util.NoSuchElementException

I am getting this error. I saw the answer to the previously asked question but I was not satisfied with the answer. When I try this command after starting java-repl i typed the following commad which is:

PezDispenser pd = new PezDispenser("Yoda"); Thanks in advance

That could because there is no element PezDispenser. According to the documentation:

Thrown by various accessor methods to indicate that the element being requested does not exist.

Your expression should work fine if you defined a class PezDipsenser.

class PezDispenser {
     PezDispenser(String name) {
           /* . . . */
     }
     /* . . . */
}

class PezDispenser { public static final int MAX_PEZ = 12; private String mCharacterName; private String mPezCount;

PezDispenser(String characterName){ mCharacterName = characterName; mPezCount = 0; } public boolean isEmpty() { return mPezCount == 0; }

public String getmCharacterName(){ return mCharacterName; }

public void load() { mPezCount = MAX_PEZ; }

}

This code still isn't working? Whats the problem

The error message I get is:

ERROR: incompatible types: int cannot be converted to java.lang.String
    mPezCount = 0;
                ^
ERROR: incomparable types: java.lang.String and int
    return mPezCount == 0;
                     ^
ERROR: incompatible types: int cannot be converted to java.lang.String
    mPezCount = MAX_PEZ;

Does converting mPezCount to an int make it work?

class PezDispenser {
  public static final int MAX_PEZ = 12;
  private String mCharacterName;
  private int mPezCount; // Should be an "int".

 PezDispenser(String characterName){
    mCharacterName = characterName;
    mPezCount = 0;
  }
  public boolean isEmpty() {
    return mPezCount == 0;
  }

  public String getmCharacterName(){
   return mCharacterName;
  }

  public void load() {
    mPezCount = MAX_PEZ;
  }  
}
