    Default Variable length arguments and Ambiguity

    In this code I have taken an overloaded method named show() with vararg. One is having int type vararg and the other is having float type vararg. When the other vararg is float then no error is there. But when it is replaced by boolean the system is giving an error. The code for both is given below.
    //code with float vararg
    class A
    {
    	void show(int ...x)
    	{
    		System.out.println("show with int");
    	}
    	void show(float ...x)
    	{
    		System.out.println("show with float");
    	}
    }
    class B_float
    {
    	public static void main(String a[])
    	{
    		A ob=new A();
    		ob.show();
    	}
    }
     
    /code
     
    //code with boolean type vararg
    class A
    {
    	void show(int ...x)
    	{
    		System.out.println("show with int");
    	}
    	void show(boolean ...x)
    	{
    		System.out.println("show with float");
    	}
    }
    class B_bool
    {
    	public static void main(String a[])
    	{
    		A ob=new A();
    		ob.show();
    	}
    }

    the system is giving an error.
    Please copy the full text of the error message and paste it here. It has important info about the error.

    To wrap your code with code tags:

    [code]
    **YOUR CODE GOES HERE**
    [/code]

    to get highlighting and preserve formatting.
    If you don't understand my answer, don't ignore it, ask a question.

    Your overloaded method has ambiguous calls in class B_float and class B_bool. For the bool call to work you need to pass a bool in (as per the below)

    class B_bool
    {
    	public static void main(String a[])
    	{
    		A ob=new A();
    		ob.show(true);
    	}
    }
