Array declaration in a class

[You Gin]

I'm faced with those two error messages while compilation for the simple class in which I'm declaring an array. Please advices why is it so.

Errors:
Description Resource Path Location Type
Syntax error on token ";", { expected after this token TwentyOneGame.java /TwentyOneGame/src line 15 Java Problem
Syntax error, insert "}" to complete ClassBody TwentyOneGame.java /TwentyOneGame/src line 24 Java Problem

Class:

class Arr {
	
     int[] anArray;              // declares an array of integers

    anArray = new int[3];      // allocates memory for 3 integers
      
    anArray[0] = 100; // initialize first element
    anArray[1] = 200; // initialize second element
    anArray[2] = 300; // etc.

}

Other than declarations, all other types of statements must be within an initializer, constructor, or method.

True. It's fine now:

class Arr {
	
	int[] anArray;              // declares an array of integers
	
	void dec() {  
    anArray = new int[3];      // allocates memory for 10 integers
		
	anArray[0] = 100; // initialize first element
    anArray[1] = 200; // initialize second element
    anArray[2] = 300; // etc.
    }
}

I cannot fully explain why your getting the errors that your getting, but I can
make what your doing work. Maybe someone in the membership is willing to
give a detailed explanation. Here is what I tried, which works BTW on my
machine.

HTH,
Jeff.

  

package arr;

public class Arr {

      int[] anArray;              // declares an array of integers  
    
Arr () {  
     anArray = new int[3];      // allocates memory for 3 integers  
         
     anArray[0] = 100; // initialize first element  
     anArray[1] = 200; // initialize second element  
     anArray[2] = 300; // etc.  
   
}    

    public static void main(String[] args) {
        Arr myArr = new Arr();
     System.out.println("anArray : " + myArr.anArray[0]);        
        
        
    }

}

....and there you have it, thank to Henry.
How could this have worked utilizing the default constructor though?

[You Gin]

Well, then I've changed the method to constructor

[Geoff Jefferson]

Actually you had no method at all.

[Rob Spoor]

In the third post there was method dec.

[Geoff Jefferson]

Sorry OP, there was a dec.
