    Default Need help with code

    Hi All

    I need some help with my code.

    public class MyInteger {
       private int value;
       public MyInteger(int number){
           value = number;
           System.out.println("Constructor created with value of " + value);
       }
       public int getValue(){
           return value;
       }
       public void setValue(int value){
           this.value = value;
       }
     
      public boolean isEven(){
          if(value % 2 == 0)
              return true; 
                      else 
              return false;
      }
      public boolean isOdd(){
          if(value % 2 != 0)
              return true;
          else
              return false;
      }
    }
     
    public class TestMyInteger {
        public static void main(String[] args){
            MyInteger integer1 = new MyInteger();
            integer1.setValue(55);
     
            MyInteger integer2 = new MyInteger();
            integer2.setValue(10);
     
            MyInteger integer3 = new MyInteger(99);
     
            System.out.println("integer1 is even " + integer1.isEven());
            System.out.println("integer1 is odd " + integer1.isOdd());
            System.out.println("integer2 is even " + integer2.isEven());
            System.out.println("integer2 is odd " + integer2.isOdd());
            System.out.println("integer3 is even " + integer3.isEven());
            System.out.println("integer3 is odd " + integer3.isOdd());
    }
    }
    I can't seem to get the value for integer1 and integer2 to pass with the setValue method. I get a runtime error stating the I need to have an int value for these two integers. Can someone help me out?

    thanks.

    Welcome to the forum! Please read this topic to learn how to post code in code or highlight tags and other useful info for new members.

    Please post your code correctly using code or highlight tags per the above link.

    --- Update ---

    You should be getting a compiler error like:
    Exception in thread "main" java.lang.Error: Unresolved compilation problems: 
    	The constructor MyInteger() is undefined
    	The constructor MyInteger() is undefined
     
    	at TestClass.main(TestClass.java:30)
    (and this is how you should post errors you want help with).

    The reason those errors occur is because the existing constructor MyInteger() requires an int argument. For example, if you changed:

    MyInteger integer1 = new MyInteger();

    to

    MyInteger integer1 = new MyInteger( 5 );

    the first error would be resolved. I don't know if that argument value is correct. I just used it as an example.
