Accessor method not returning the correct value in Java-CodePudding

I am testing a Class in Java and I have written an if-else statement to ensure that the value is between 0-4.5. If it is not, the accessor method should return 0 as a value. However, when I test a number that is out of range, whether above or below, it still prints that value instead of 0.

I am very new to Java, I appreciate any insight into where I may have gone wrong.

Below, I have my accessor and mutator method, as well as a test where the value is above the specified range:

public double getNumber()
{
    return this.num;
}

public void setNumber(double num)
{
    if(num >= 0.0 && num <= 4.5)
    {
        this.num = num;
    }
    else
        this.num = 0.0;
}



static void Test_setNumber()
{
    ClassName test = new ClassName(400.0);

    applicant.setNumber(460.5);

    double expected = 460.5;
    double actual = applicant.getNumber();
}

    public static class  ClassName{        
        private  double  num ;
        public ClassName() {            
        }       
        public double  getNumber() {
            return num;
        }
        public void setNumber(double  num) {                       
            if(num >= 0.0 && num <= 4.5) {
                this.num = num;
            }
            else
                this.num = 0.0;
        }                
    }   
    public static void main(String[] args) {
        ClassName test = new ClassName();
        test.num = 5.5;
        double expected = 0.0;
        
        double actual = test.getNumber();
        System.out.println(actual);
        
        test.setNumber(5.5);
        System.out.println(test.getNumber());
    }    
}

You should know when set and get the value num . result :

5.5
0.0

    ClassName test = new ClassName(5.0);

You have to sent in ClassName class's full code to let us see how you set in the value. I dont see how the class ClassName(double) call the setNum.
